Which happened first: fall of nanjing, italy invades ethiopia, germany annexes the sudetenland? fall of nanjing italy invades ethiopia germany annexes the sudetenland

The correct answer is Italy invades Ethiopia

The Fall of Nanjing happened in 1938 after a four months battle. Sudetenland was also annexed by Hitler in 1938. Invasion of Ethiopia happened during the Second Italo-Ethiopian war in 1935, which is 3 years before the other two events, even though the war with Ethiopia did last until 1939, which is four years after the invasion began.
