Biography.
Unzaga was born in Málaga, Spain, the son of a well-known Basque family. He served in the Italian war of 1735 and went to Havana in 1740, where he was appointed lieutenant governor of Puerto Príncipe, Cuba (now Camagüey) and later of Santiago de Cuba. During the Seven Years' War he defended Havana against a British siege, in 1762.
Unzaga accompanied Alejandro O'Reilly to New Orleans in 1769 to put down the Rebellion of 1768 by French and German colonists objecting to the cession of Louisiana to Spain via the Treaty of Fontainebleau (1762). Following the formal establishment of the cabildo (council), Unzaga became governor on December 1, 1769. In 1775, he married Elizabeth St Maxent, the first daughter of Gilbert Antoine de St. Maxent, the wealthiest man in Louisiana.
Unzaga was noted for allowing open trade. During the summer of 1776, he secretly helped Patrick Henry and the Americans by privately delivering five tons of gunpowder from the king's stores to Captain George Gibson and Lieutenant Linn of the Virginia Council of Defense. The gunpowder was moved up the Mississippi under the protection of the flag of Spain, and was used to thwart British plans to capture Fort Pitt in Pennsylvania.
From June 17, 1777, to December 10, 1782, Unzaga served as Captain General of Venezuela. In 1783 he became governor of Cuba, where one of his first actions was ordering a halt to the unrestrained cutting of cedar trees. As Governor of Cuba and Captain General of Havana, a position he would hold until 1785, in April of 1783 he received the visit of Prince William of England, the future King William IV, with whom he reached preliminary agreements for the Treaty of Paris (1783). Later he continued to attend to the requests for help from George Washington and Robert Morris to finally achieve the birth of the United States of America. After his retirement, he returned to his native Málaga, where he occupied as Lieutenant General the General Command of the coasts of the kingdom of Granada. Their residences would serve as the consular agency of the United States of America in Málaga after the port of Málaga started free trade with the United States of America.
