King Thibaw of Myanmar tried to strike a pact with Italy and Germany. These reasons were enough for the British to feel alarmed. They declared war against King Thibaw when he levied a fine on the Bombay-Burma Trading Corporation, a British company. This led to a war being declared against Burma.
King Thibaw surrendered and was imprisoned by the British to ensure that he would not be able to rise against the British or have any contact with his subjects.
