William Walker
http://en.wikipedia.org/wiki/William_Walker_(soldier)"William Walker (May 8, 1824 – September 12, 1860) was an American filibuster who attempted to conquer several Latin American countries in the mid-19th century. He appointed himself president of the Republic of Nicaragua in 1856 and ruled from that year to 1857. He was executed by the government of Honduras in 1860."
Come on guys! He appointed HIMSELF the president of Nicaragua!
"In the role-playing game GURPS' book Alternate Earths, one of the alternate Earths mentioned has its point of divergence in the moment where Walker decided to revoke Vanderbilt's Transit Company's charter. In this alternate Earth, Walker decides to support it, and as a result he remains as the president of Nicaragua, conquers most of Central America and supports the Confederacy in the American Civil War, which ends with the victory of the South and the official secession of the United States of America into two different countries."
