The Qajar dynasty was probably one of the weakest in Iran's history. After the World War I, Russia and Britain entered a fierce power struggle in Iran. The Qajar court was corrupt and deeply under influence of foreign missionaries. The last Qajar king was only a teenager when Reza Khan who was the commander of a Kazak brigade trained by Russians marched with his troops from Qazvin to Tehran on Feb, 18, 1921. Four days later he seized key locations of the capital almost with no resistance and forced the government to resign. Ahmad Shah appointed Seyyed Ziaoddin Tabatabayi as the Prime Minister and Reza Khan started to silence opposition groups as the minister of war in Gilan and Khorasan. Four years later the Qajar dynasty was overthrown and Reza khan was put on the throne by the British; yet deposed and replaced by his son in 1941.
