Reza Shah’s Ten Commandments
The Majlis, convening as a Constituent Assembly, declared him the Shah (King) of Iran on 12 December 1925, pursuant to the Constitution of Iran. Three days later, on 15 December, he took his imperial oath and thus became the first shah of the Pahlavi dynasty. At this time he was 47 years old. Reza Shah's coronation took place much later, on 25 April 1926. It was at that time that his son, Mohammad Reza Pahlavi, was proclaimed the Crown Prince of Persia – to rule after his father.
