The '''British Empire''' was a global empire acquired and ruled by the [[Kingdom of Great Britain]] (or, from 1801 the United Kingdom of Great Britain and Ireland, called "Great Britain" or "Britain" in historical studies). After 1945 the Empire collapsed and most former colonies joined the loosely organized "British Commonwealth," and many—including Canada and Australia—kept the monarch as their nominal head of state. | The '''British Empire''' was a global empire acquired and ruled by the [[Kingdom of Great Britain]] (or, from 1801 the United Kingdom of Great Britain and Ireland, called "Great Britain" or "Britain" in historical studies).
