Carlism (; ; ; ) is a traditionalist and legitimist political movement in Spain seeking the establishment of a separate line of the Bourbon dynasty on the Spanish throne. This line descended from Don Carlos, Count of Molina (1788–1855), and was founded due to dispute over the succession laws and widespread dissatisfaction with the Alfonsine line of the House of Bourbon. The movement was at its strongest in the 1830s but had a revival following Spain's defeat in the Spanish–American War in 1898, when Spain lost its last remaining significant overseas territories of Cuba, Guam, the Philippines, and Puerto Rico to the United States.
