[edit] Notes
- ↑ The British Empire was the common term for the United Kingdom and its overseas possessions at this time. The term refers to the colonies it controlled, to the Indian Empire, which, while not officially designated a colony, was functionally indistinguishable from one, and the British Dominions - former colonies which were self-governing in most respects but whose foreign policy was controlled by London; Canada, Australia, Newfoundland, New Zealand and South Africa.
- ↑ Entries on a yellowish background refer to severed diplomatic relations only, not to actual declarations of war
