George VI Technically Fought Himself

During World War II, British King George VI was at war with Nazi Germany as king of the United Kingdom but at peace with it as king of neutral Ireland. Ireland's 1936 External Relations Act left him a limited role in foreign affairs, under which he formally accredited German diplomats on the Irish government's advice. After British India split into the independent dominions of India and Pakistan in August 1947, George became king of both, and the Indo-Pakistani War later that year technically put him at war with himself.
