Alfonso XII of Spain

Alfonso XII was proclaimed king after a military coup led by General Mart

Alfonso XII's forces defeated the Carlist rebels, ending the Third Carlist War. This victory consolidated his rule and eliminated the Carlist challenge to the Bourbon monarchy, bringing peace to Spain after years of civil conflict.

Alfonso XII oversaw the adoption of a new constitution that established a constitutional monarchy with a bicameral parliament. The constitution provided a framework for political stability and alternation between two main parties, the Conservatives and Liberals.

Alfonso XII married Maria Christina of Austria, his second wife. This marriage produced the future Alfonso XIII and helped secure the Bourbon succession, ensuring the dynasty's continuity after the king's early death.

Alfonso XII died of tuberculosis at the age of 27, leaving his pregnant wife as regent. His death created a succession crisis, but his posthumous son Alfonso XIII was born later that year, ensuring the continuation of the Bourbon monarchy.
