The Foreign Office was formed in
1782 to oversee Britain's foreign affairs, which had previously been co-administered by
the Southern and Northern Departments of the Secretary of State. In addition to foreign
affairs, the Foreign Office was also responsible for British protectorates like
Cephalonia.
As the territory of the British empire shifted, the responsibility boundaries between
the Foreign and Colonial Offices were not always clear. As regards
HBC Governor J. H. Pelly's inquiry about the
Oregon Territory treaty,
Benjamin Hawes suggested to
Lord Grey that the issue should be forwarded to the Foreign Office. The Foreign Office was
merged into the Foreign and Commonwealth Office in
1968.
