The Third Carlist War was a conflict in Spain that took place from 1872 to 1876. It was fought between the supporters of Carlos VII, who claimed the Spanish throne, and the government loyal to Isabella II and her successors. This war was part of the larger Carlist Wars, which were rooted in disputes over the Spanish monarchy and issues of regional autonomy. The war primarily occurred in the northern regions of Spain, particularly in Catalonia and Navarre. It ended with the defeat of the Carlist forces, leading to the consolidation of the Spanish monarchy under the Bourbon dynasty. The conflict had significant social and political implications for Spain, shaping its future governance.
