The Alied Powers is the friends the Axis Power is the enemy. The Alied Powers were allies with 50 nations including Britian, France, Australia, Canada, and Mexico. The Axis Powers were allied with 6 other nations including Hungary, Rumania, Thailand, and Bulgaria. Over time the Soviet Union and Hitler signed a secret agreement. When Hitler took over Britian he also tried to take over the Soviet Union too. His plan didn’t work out that well and the Soviet Union won instead of Hitlers army. So the Soviet Union joined the Allied powers.
