Final answer:
Reza Shah and Muhammad Reza Shah were rulers of Iran during the 20th century. The Shah was supported by the United States and Western oil companies, while traditionalist Muslim leaders and those who resented Western influence did not support him.
Step-by-step explanation:
Reza Shah and Muhammad Reza Shah were rulers of Iran during the 20th century. Reza Shah, also known as Reza Pahlavi, came to power in 1923 and implemented modernization reforms, including granting voting rights to women. However, his authoritarian rule and close ties to foreign powers led to public discontent. Muhammad Reza Shah, his son, took over in 1941 and continued his father's policies with the backing of the United States and Western oil companies. While he implemented some reforms, he faced opposition from traditionalist Muslim leaders and liberal Iranians who sought more political freedom and equal distribution of wealth.
Support for the Shah came primarily from the United States and Western oil companies, who saw him as a stable ally and protector of their interests. The Shah received economic and military aid from the US in exchange for political support. On the other hand, many Iranians, especially traditionalist Muslim religious leaders and those who resented Western influence, did not support the Shah. They viewed his regime as oppressive, corrupt, and favoring foreign interests over the needs of the Iranian people.
