Heads of Agreement (1981)

The Heads of Agreement was a 1981 document proposing a solution to the Guatemalan claim to Belizean territory. Created in February and signed on 11 March 1981 in London, the agreement sought to propose future bases for negotiations between the United Kingdom, Belize and Guatemala over the dispute. The document's rejection created a national security crisis in Belize in March and April 1981.
