In a parallel universe visited by the Third Doctor, the American Confederation was a nation state established following the victory of the Confederate States of America in the American Civil War during the 1860s.
The American Confederation was led by a president, who represented the Americas on the Conclave, a super cabinet designed to ensure world peace. It was composed of the leaders of the parallel Earth's five continents. The acting president after I-Day was a Floridian man named Sandobal. (PROSE: The Face of the Enemy)
