Louis I, King (portugal) : All Data
Louis I was the King of Portugal who reigned from 1861 to 1889. During his tenure, Portugal was involved in several significant conflicts. One of the most important wars that occurred during his rule was the War of the Two Brothers, which took place from 1864 to 1865. This conflict was a civil war between the liberal forces of King Pedro V and the absolutist forces of his brother, Miguel. Another notable conflict was the British Ultimatum of 1890, which occurred after Louis I's reign but had its roots in the colonial disputes between Portugal and Britain during his rule.
