I want to know the answer to the following question:
When was Reza Shah forced to abdicate in Iran?
All the background I'm provided with is that "In 1941, Reza Shah was forced to abdicate in favor of his son, Mohammad Reza Pahlavi, and established the Persian Corridor, a massive supply route that would last until the end of the ongoing war.". Is that enough to answer the question?
Answer: yes
