Between 1889 and 1939 Britain created security for itself through alliances, rearmament, or appeasement (either alone or in some combination). The existing literature emphasizes the role of geopolitics, domestic characteristics, and individual idiosyncrasies to explain Britain's choices.

Supporters and opponents understood that how Britain secured itself would create internal winners and losers. Supporters and opponents also recognized that any changes in the security strategy would have domestic redistributional consequences. I apply this model to Britain and use a longitudinal controlled comparison over three periods: 1889—1914, 1914—1919, and 1919—1939.
