Juan Antonio de Urbiztondo

Juan Antonio de Urbiztondo y Eguía (7 January 1803, San Sebastián – 26 April 1857, Madrid) was a Spanish military and the marquis of La Solana. In 1814 he became a knight's page in the Spanish Army, fought against the government of Trienio Liberal, and then became the inspector of the Royalist Volunteers. Madrid historians mentioned Urbiztondo's participation to a dispute at the Royal Palace of Madrid, which involved the Duke of Cádiz, the Duke of Valencia and Joaquín Osorio y Silva-Bazán (who was killed by Urbiztondo).

In 1833 he was imprisoned at Mérida due to the accusation that he is supposed-to-be connection to Carlism, but he managed to escape to Portugal.

Expedition against the Sultanate of Sulu

In December 1850, Urbiztondo led a naval expedition to the Sulu Archipelago. They visited several islands, causing destruction and casualties. Upon reaching Jolo, they faced hostility from Sultan Mohammad Pulalun Kiram and failed to obtain any concessions. Unable to invade the fortified city, they sailed to Tunkil and conducted a raid, resulting in more casualties and destruction.

In April 1851, the Sultan of Sulu signed a treaty with Spain recognizing Spanish sovereignty over the Sulu Sultanate and its dependencies. The treaty also allowed Spain to establish a trading factory and a naval station in Jolo.
