Prior to 1962, the area was a part of the Falkland Islands Dependencies and as such was administered by the
Governor of the Falkland Islands. The British Antarctic Territory was established as a separate
British overseas territory in 1962. From 1962 to 1990, the Governor of the Falkland Islands also held the office of high commissioner for the territory. In 1990, administration of the BAT was transferred to a separate commissioner based in London. Between 1998 and 2024, the commissioner of the BAT also served as
Commissioner of the British Indian Ocean Territory. ==List of high commissioners and commissioners==
