Abdul Reza Pahlavi was a member of Iran's Pahlavi dynasty. He was a son of Reza Shah and a half-brother of Mohammad Reza Pahlavi.

Reza Shah Pahlavi was an Iranian military officer and the founder of the Pahlavi dynasty. As a politician, he previously served as minister of war and prime minister of Qajar Iran and subsequently reigned as Shah of Pahlavi Iran from 1925 until he was forced to abdicate after the Anglo-Soviet invasion of Iran in 1941. He was succeeded by his eldest son, Mohammad Reza Shah. A modernizer, Reza Shah clashed with the Shia clergy, but also introduced many social, economic, and political reforms during his reign, ultimately laying the foundation of the modern Iranian State. Therefore, he is regarded by many as the founder of modern Iran.
