Alvear, Carlos M

(1789-1852) fought for the Spanish Army during the Napoleonic Wars, but on the side of revolutionaries during the War of Independence. He had a long political fight with Rosas and attempted to unite Argentina, Bolivia, Paraguay, Uruguay and Chile into one large republic, asking Simón Bolivar to be its first president. He was later named Argentina’s first ambassador to the United States, a move by Rosas to get Alvear out of his way.
