King Amadeo I was a monarch from the House of Savoy who ruled as the King of Spain from 1871 to 1873. He was born on May 30, 1845, in Turin, Italy, and was the son of King Victor Emmanuel II of Italy. His reign was marked by political instability and challenges, leading to his abdication after just two years. Amadeo's ascension to the Spanish throne was largely due to the desire for a constitutional monarchy following the Spanish Civil War. Despite his efforts to unify the country, he faced opposition from various factions, ultimately resulting in his departure from Spain in 1873.
