Italian Peninsula
Modern-day Countries in this region
Bronze Age
The Bronze Age on the Italian Peninsula marked the emergence of complex societies, driven by advancements in metallurgy, agriculture, and trade. The period saw the rise of early cultures such as the Terramare in northern Italy and the Apennine culture in central and southern Italy. These societies built settlements near rivers and fertile plains, utilizing bronze tools and weapons that improved their agricultural productivity and craftsmanship.
Coastline Changes
Important changes to the coastlines throughout History.
Iron Age
The period saw the emergence of distinct cultural groups, most notably the Villanovan culture in northern and central Italy, which is considered the precursor to the Etruscans. The Villanovans were skilled metallurgists, known for their cremation burials and urnfields, and their settlements began to show signs of early urban planning.
In southern Italy and Sicily, contact with Greek colonists introduced Hellenic cultural elements. By the late Iron Age, Greek settlements emerged, creating a fusion of local Italic and Greek traditions that would profoundly influence the region's history.
The Italics, a collection of Indo-European tribes, also began to migrate into the peninsula during this period. Groups such as the Latins, Samnites, and Umbrians settled in various regions, each developing unique languages, traditions, and governance structures.

Antiquity
Antiquity marked the zenith of cultural, political, and military development on the Italian Peninsula, driven by the dominance of the Etruscans, Greeks, and eventually the Romans. The period began with the flourishing of the Etruscan civilization (c. 8th-3rd century BCE) in central Italy. The Etruscans built sophisticated cities, developed advanced engineering techniques, and played a critical role in the cultural and technological evolution of early Rome. Their influence is evident in Roman religious practices, urban planning, and art.
The Greek colonies in southern Italy and Sicily, collectively known as Magna Graecia, thrived during this period, bringing Hellenic culture, philosophy, and architecture to the peninsula. Cities such as Syracuse, Tarentum, and Naples became centers of learning and trade, fostering interactions between Greek, Italic, and Etruscan peoples.
By the late 6th century BCE, the city of Rome began its rise. Initially ruled by kings, Rome transitioned to a Republic in 509 BCE, laying the foundations for one of history’s greatest empires. During the Republic, Rome expanded its influence across the Italian Peninsula through military conquest and strategic alliances. By the 3rd century BCE, Rome defeated the Etruscans, Samnites, and Greek colonies, uniting the peninsula under its control.
The Roman Empire (27 BCE-476 CE) brought unprecedented prosperity and unity to the Italian Peninsula, turning it into the political, economic, and cultural center of the Mediterranean world. Rome’s infrastructure-roads, aqueducts, and monumental architecture-transformed the region. Latin became the lingua franca, and Roman law, governance, and citizenship created a cohesive identity across diverse populations.
However, repeated invasions by Germanic tribes, internal political strife, and economic decline eroded Roman power. By 476 CE, the fall of the Western Roman Empire marked the end of Antiquity on the Italian Peninsula, ushering in the Early Middle Ages.

Western Roman Empire
Barbarian Invasions
Early Middle Ages
When the Western Roman Empire fell in 476 AD, the Italian Peninsula fell to Odoacer, who declared himself king. However, Odoacer’s reign was short-lived as he was soon overthrown by the Ostrogoths, led by Theodoric the Great, who established their kingdom over Italy. The Eastern Roman Empire, or Byzantine Empire, under Emperor Justinian I launched the Gothic War (535-554 AD) in an attempt to reconquer Italy. Though ultimately successful, the Byzantine reconquest left the peninsula devastated, with much of its infrastructure and urban life in ruin. The war was far more destructive than the earlier Barbarian invasions, leaving Italy a shadow of its former splendor.
Byzantine control in Italy proved fragile. In the late 6th century, another Germanic people, the Lombards, invaded Italy. Over the course of the next few decades, the Lombards gradually conquered most of the peninsula, leaving only Latium and Romagna under Byzantine control. The remnants of Byzantine rule in the region also gave rise to the Republic of Venice, which became a significant maritime power. During this period, the Christian Church emerged as a dominant force in Italy.
By the 8th century, Charlemagne’s Frankish Empire annexed the Lombard Kingdom, and the Italian Peninsula became divided into three main parts: northern Italy, which was the Kingdom of Italy under Frankish control; Latium and surrounding regions, which were left under the Pope’s control, forming the foundation of the Papal States; and the south, where Lombard Kingdoms remained autonomous and the Byzantines still held some coastal territories.
Sicily and Sardinia had different fates. Sardinia fragmented into several local kingdoms known as the Judicates, while Sicily, initially a Byzantine territory, fell to the Arabs in the 9th century, who established the Emirate of Sicily.
By the end of the Early Middle Ages, in 986, the Kingdom of Italy became one of the core territories of the Holy Roman Empire, a new political entity that replaced the older Frankish Empire.
Frankish Partitions
The Frankish Kingdom was partitioned and reuinited several times as the Frankish rulers used to divide their territories equally among their heirs. This lead also to a number of wars and revolts.

High Middle Ages
During the High Middle Ages, Italy became increasingly fragmented. The Kingdom of Italy, once part of the Holy Roman Empire, slowly disintegrated into a patchwork of independent communes and maritime republics, particularly after the reign of Emperor Frederick Barbarossa in the 12th century. His efforts to consolidate control over northern Italy were met with resistance from local Italian rulers, culminating in the formation of the Lombard League, an alliance of northern Italian cities that successfully defeated Barbarossa at the Battle of Legnano in 1176. The Papal States, under the authority of the Pope, gained more stability and power in central Italy, consolidating their control over the region. However, the territories of Romagna began to fragment into smaller, autonomous communes, each vying for independence or influence.
The Italian communes often became the domain of powerful local families, such as the Medici of Florence, who would go on to play a significant role in the politics of Italy.
In southern Italy, the Normans emerged as the dominant force. After conquering the Lombard kingdoms, they drove the Byzantines out of the region and eventually took control of Sicily. By the late 11th century, the Normans had established the Kingdom of Sicily (which controlled both Sicily and southern Italy), which became a prosperous and culturally diverse state, blending Latin, Greek, and Arab influences. However, following the death of the Norman king in 1194, the kingdom passed into the hands of the Hohenstaufen dynasty, and later the Angevins. After the rebellion of 1282, the Kingdom of Sicily was divided into the Kingdom of Naples, under Angevin control, and the Kingdom of Sicily, which came under the influence of the Aragonese.
Meanwhile, the Aragonese extended their power over Sardinia, bringing an end to the age of the Judicates and effectively incorporating the island into their domains.
At the end of this period, San Marino emerged as an independent polity. Claiming to be the oldest surviving republic in the world, San Marino maintained its independence despite the shifting political landscape of the Italian Peninsula. The small republic, nestled in the Apennine Mountains, managed to avoid the wars and conquests that swept across Italy during this era, thanks to its strategic diplomacy and geographic isolation.

High Middle Ages
Late Middle Ages
The Late Middle Ages in Italy were marked by increasing political and social instability, alongside the rise of powerful city-states and regional entities. The Papal States continued to exert control over central Italy, while in the north, the old kingdom of Italy had fragmented into various city-states. Cities such as Florence, Venice, and Milan became increasingly independent, governed by merchant elites and noble families.
In the 14th century, Italy also saw the rise of significant cultural and artistic movements, with the Italian Renaissance beginning to take shape in cities like Florence, Rome, and Venice. This cultural flourishing was not matched by political unity, however, as these city-states were often in conflict with each other. The territorial fragmentation, combined with the arrival of foreign powers seeking to control parts of Italy, set the stage for the Italian Wars (1494-1559), a series of conflicts that involved France, Spain, and the Holy Roman Empire.
In the south, the Kingdom of Naples remained a target for various foreign powers. The region was embroiled in battles for control, particularly between the Angevins, the Aragonese, and later the Spanish. In Sicily, the Aragonese had established dominance following the revolt of the Sicilian Vespers in 1282, and by the 15th century, Spain had gained significant influence over the entire southern peninsula.
By the late 15th century, Italy had become a patchwork of small kingdoms, republics, and principalities, each vying for power, but none able to unite the peninsula under a single rule. The lack of unity would continue to hinder the development of a unified Italian state until the 19th century.
Late Middle Ages
Late Middle Ages
European wars of religion
Were a series of wars in Europe (and the overseas possessions of European countries) the 16th, 17th and early 18th that started after the Protestant Reformation. Although the immediate causes of the wars were religious, the motives were complex and also included territorial ambitions.
Italian Wars
Were a series of conflicts covering the period between 1494 to 1559, fought mostly in the Italian peninsula, but later expanding into Flanders, the Rhineland and the Mediterranean Sea. The primary belligerents were the Valois kings of France, and their Habsburg opponents in the Holy Roman Empire and Spain.
Early modern period
The Italian Wars (1494-1559), fought between France, Spain, the Holy Roman Empire, and Italy's various states, left much of the peninsula under foreign occupation. By the mid-16th century, Spain emerged as the dominant power in Italy, controlling most of the southern peninsula, including Naples and Sicily, as well as Lombardy and Sardinia while the Papal States maintained control over central Italy. The Republic of Venice, although a major maritime power, saw its influence waning as the Ottomans grew more powerful in the eastern Mediterranean.
The War of Spanish Succession (1701-1714) and the Treaty of Utrecht (1713) shifted the balance of power in Italy, with much of northern Italy falling under Austrian Habsburg control.
At the same time the many independent communed, republics and domains of northern and central Italy slowly merged in few major states like the Grand Duchy of Tuscany, the Kingdom of Sardinia, the Republic of Venice, the Republic of Genoa, and the Duchy of Modena and Reggio.
Early modern period
War of the Spanish Succession
The death of childless Charles II of Spain in November 1700 led to a struggle for control of the Spanish Empire between his heirs, Philip of Anjou and Charles of Austria, and their respective supporters. It was a global war, with fighting taking place in Europe, Asia, and America. At the end of the war, Philip II, who was the successor chosen by Charles II as a descendant of Charles' paternal half-sister Maria Theresa, became King of Spain and of its overseas empire. The Spanish possessions in Europe were partitioned between various European Monarchies.
Early modern period
War of the Polish Succession
Was a major European conflict sparked by a Polish civil war over the succession to Augustus II of Poland.
War of the Austrian Succession
Was a European conflict caused by the succession to the Habsburg Domains. Maria Theresa succeeded her father Charles VI, and the opposition to female inheritance of the throne was a pretext for starting a war. It was a global conflict that saw fight in Europe, Asia, America and Africa.
French Revolutionary and Napoleonic Period (1789-1815)
In 1796 French forces invaded northern Italy, defeating the Austrian Empire and other local powers. By 1800, much of northern Italy had been reorganized into satellite republics under French influence, such as the Cisalpine Republic and the Ligurian Republic. The Kingdom of Naples also fell to French forces in 1806, and the Bourbon monarchy was replaced by a French-friendly regime.
Napoleon implemented sweeping reforms across the peninsula, including legal and administrative changes that mirrored those in France. The Napoleonic Code was introduced in much of Italy, replacing feudal laws with more modern legal systems.
Following Napoleon's defeat, the Congress of Vienna (1815) redrew the map of Europe. Most of the territories that had been under French control, including the Papal States, Naples, and Lombardy, were returned to their previous rulers or placed under new monarchies, thus restoring the pre-revolutionary order.
San Marino managed to retain its independence even during Napoleon's campaigns. Napoleon respected the tiny republic’s sovereignty, describing it as a "model republic." San Marino avoided annexation and even provided refuge to political exiles during this turbulent period.
French Revolutionary and Napoleonic Wars
Were a series of conflicts between France and several European monarchies between 1792 and 1815. They encompass first the French Revolutionary Wars against the newly declared French Republic and from 1803 onwards the Napoleonic Wars against First Consul and later Emperor Napoleon Bonaparte. They include the Coalition Wars as a subset: seven wars waged by various military alliances of great European powers, known as Coalitions, against Revolutionary France - later the First French Empire - and its allies.

19th Century
The Restoration period that followed Napoleon’s downfall saw a return to conservative monarchies across Europe, including Italy. The Congress of Vienna re-established Austrian control over much of northern Italy, while the Kingdom of Sardinia-Piedmont emerged as the most powerful state in the north. However, the concept of a unified Italian nation began to take shape, particularly under the influence of the Risorgimento, a movement that sought to unify the various states and regions of Italy into a single nation.
The process of unification was slow and fraught with conflict. In the 1830s and 1840s, a series of uprisings and revolutions occurred throughout the peninsula, fueled by nationalist and liberal ideas. These early revolutions were crushed by conservative forces, particularly the Austrian Empire, which maintained control over northern Italy.
In the 1850s and 1860s, the Kingdom of Sardinia, with the help of France, began to push against Austrian control in northern Italy. In 1859, Sardinia’s victory over Austria in the Second Italian War of Independence paved the way for the annexation of Lombardy and parts of central Italy. In 1860, Garibaldi's famous Expedition of the Thousand led to the conquest of Sicily and southern Italy, which were then incorporated into the Kingdom of Sardinia. The Kingdom of Italy was formally proclaimed in 1861, with Victor Emmanuel II as its first king. However, not all regions were immediately unified. Rome and the surrounding Papal States remained under papal control until 1870, when Italian forces captured the city, completing the unification process. This also marked the end of the Papal States and the establishment of Rome as the capital of a unified Italy.
San Marino supported the Risorgimento movement by offering refuge to Italian nationalists such as Giuseppe Garibaldi. Despite its small size, the republic was recognized for its contributions to Italian unification, and in return, its independence was formally guaranteed by the Kingdom of Italy in the 1862 treaty. Pope Pius IX refused to recognize the new Italian state and declared himself a "prisoner in the Vatican," beginning the so-called "Roman Question," a political standoff between the Papacy and the Italian government that would last until the 20th century.

German Unification Wars
Were a series of wars that resulted in the creation of the German Empire under Prussian leadership in 1871.
From 1900 to the End of World War II
The early 20th century in Italy was marked by the consolidation of the newly unified state and the growing tension of the First World War. Despite achieving unification, Italy faced economic challenges, social unrest, and regional divisions. The industrial revolution had transformed northern Italy, while southern Italy remained largely agrarian and underdeveloped, leading to widespread poverty and dissatisfaction. In the 1910s, Italy entered World War I on the side of the Allies, hoping to gain territory from Austria-Hungary. The war proved to be costly, and the social and economic consequences were severe. The post-war period saw the rise of political extremism, with the Socialist and Fascist movements gaining strength.
Fascism, led by Benito Mussolini, rose to power in 1922, with Mussolini becoming Prime Minister and dictator. Mussolini’s regime sought to restore Italy to its former glory, emphasizing nationalism, militarism, and the centralization of power. Mussolini invaded Ethiopia in 1935, hoping to build a new Roman Empire, but his efforts strained relations with other European powers. When World War II broke out in 1939, Italy initially allied with Nazi Germany, but Mussolini’s regime was increasingly weakened as the war dragged on. In 1943, after a series of military defeats, Mussolini was overthrown and arrested, and Italy began to negotiate peace with the Allies. In 1945, Italy was liberated by Allied forces, and the Fascist regime was officially dismantled.
In 1929, the Lateran Treaty was signed between the Vatican and Benito Mussolini’s fascist government, resolving the "Roman Question." The treaty established the Vatican City State as an independent sovereign entity, making it the smallest country in the world. The Vatican remained neutral during World War II, but it was also a center for diplomatic activity and a refuge for Jews and political exiles fleeing persecution.
San Marino remained neutral during both World Wars, despite its proximity to key battlefields. During World War II, it provided refuge to thousands of displaced persons and remained largely unscathed, though it was briefly occupied by German forces in 1944 before being liberated by the Allies.
World War I
Was a global conflict between two coalitions, the Allies (primarily France, the United Kingdom, Russia, Italy, Japan, and the United States) and the Central Powers (led by Germany, Austria-Hungary, and the Ottoman Empire). It was mainly caused by the competition of the western countries over domain in Europe and in the rest of the world with their colonial empires. The war ended with the defeat of the Central Powers. The war also caused the Russian Revolution and the ensuing Russian Civil War.
Austria-Hungary Fragmentation
1900-1945
World War II
Was a global conflict that lasted from 1939 to 1945 (it started sooner in certain regions) between the Axis Powers (mainly Germany, Japan and Italy) and the Allies (mainly the Soviet Union, the U.S.A., the U.K., China and France). It was the war with more fatalities in history. The war in Asia began when Japan invaded China on July 7, 1937. The war in Europe began when Germany invaded Poland on September 1, 1939. The war ended with the complete defeat of the Axis powers, which were occupied by the Allies.
World War II
Cold War Period
Following World War II, Italy became a republic in 1946 after a referendum abolished the monarchy. The country was severely weakened by the war, but the post-war period also marked the beginning of Italy’s recovery and its integration into Western Europe. Italy became a founding member of the North Atlantic Treaty Organization (NATO) in 1949 and the European Economic Community (EEC) in 1957, signaling its alignment with the West during the Cold War.
Politically, Italy experienced significant instability, with frequent changes in government and the rise of both left-wing and right-wing extremism. The Italian Communist Party became one of the largest in Western Europe, but Italy remained firmly within the Western bloc, despite the strong presence of the Communist Party. During the 1970s, Italy faced the "Anni di Piombo)", a period of intense political violence from both far-left and far-right groups.
Economically, Italy experienced a "miracle" in the 1950s and 1960s, as it became one of the world’s leading industrial nations. The economic boom, however, was uneven, and regional disparities between the industrialized north and the underdeveloped south persisted. Italy's economy was further boosted by its involvement in the European Economic Community and later the European Union.
Cold War
Post-Cold War Period (1990-2010)
The 1990s saw the dismantling of Italy's post-war political structure, which had been dominated by the Christian Democrats and the Italian Communist Party. In the early 1990s, widespread corruption scandals involving leading political figures led to the fall of the old political order and the rise of new political parties, most notably the Forza Italia party, led by media mogul Silvio Berlusconi. Berlusconi’s populist and media-savvy approach reshaped Italian politics, with him serving as Prime Minister for several terms.
Italy also played a significant role in the creation of the European Union's single currency, the Euro, and continued to be a prominent member of European and international organizations. However, Italy faced economic challenges, including high levels of public debt, a slow economic recovery after the global financial crisis, and rising unemployment, particularly among youth.
2010s and 2020s
The 2010s and 2020s were characterized by significant social, political, and economic challenges for Italy. The aftermath of the global financial crisis of 2008 left Italy with a sluggish economy and ongoing struggles with public debt and unemployment. In the political arena, Italy experienced frequent changes in government, with coalition governments becoming the norm. The rise of populist movements, including the Five Star Movement and the League, marked a shift in the political landscape, with these parties pushing for reforms, challenging the European Union, and advocating for stronger national sovereignty.
