Final answer:
Italy invaded Ethiopia in the 1930s during Benito Mussolini's efforts to expand Italian territory and power, leading to Ethiopia's conquest in 1936.
Step-by-step explanation:
The correct match between a nation and another nation that it invaded in the 1930s, according to the options provided, is Italy invading Ethiopia. This significant historical event occurred when Italian forces, under the leadership of dictator Benito Mussolini, invaded Ethiopia in October 1935, seeking to expand their territory and assert dominance in East Africa. Despite Ethiopia's resistance and an appeal to the League of Nations, by 1936 Italy had successfully conquered Ethiopia, undermining the authority of the League of Nations and contributing to the destabilization of the international order that preceded World War II.
