Declarations of War
The following table shows the timeline of the several declarations of war [2] among the belligerent powers.
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; Australia, Canada, Newfoundland, New Zealand and South Africa. At that time, the United Kingdom of Great Britain and Ireland also included the entire island of Ireland.
- ^ Entries on a yellowish background refer to severed diplomatic relations only, not to actual declarations of war
