The United States established a consulate in British Honduras (now Belize) on March 3, 1847. Prior to independence Belize had been a British colony since 1862, changing its name to Belize from British Honduras in June 1973.
In the 1960s the United States sought and ultimately failed to mediate a dispute
between Belize and Guatemala over contested Belizean
territory dating back to an 1859 treaty between Imperial
Spain and Great Britain.
