social groups. Although he himself was of Iranian Mazanderani descent, his government carried out an extensive policy of Persianization trying to create a single, united and largely homogeneous nation, similar to Mustafa Kemal Atatürk's policy of Turkification in Turkey after the fall of the Ottoman Empire. Early life Reza Shah Pahlavi was born in the town of Alasht in Savadkuh County, Mazandaran Province, in 1878, to son of Major Abbas-Ali Khan and wife Noush-Afarin. His mother was a Georgian Muslim immigrant from Georgia (then part of the Russian Empire), whose family had emigrated to Qajar Iran when it was forced to cede all of its territories in the Caucasus following the Russo-Persian Wars several decades prior to Reza Shah's birth. His father was a Mazanderani, commissioned in the 7th Savadkuh Regiment, and served in the Siege of Herat in 1856. Abbas-Ali died suddenly on 26 November 1878, when Reza was barely 8 months old. Upon his father's death, Reza and his mother moved to her brother's house in Tehran. She remarried in 1879 and left Reza to the care of his uncle. In 1882, his uncle in turn sent Reza to a family friend, Amir Tuman Kazim Khan, an officer in the Persian Cossack Brigade, in whose home he had a room of his own and a chance to study with Kazim Khan's children with the tutors who came to the house. When Reza was sixteen years old, he joined the Persian Cossack Brigade. In 1903, when he was 25 years old, he is reported to have been guard and servant to the Dutch consul general Fridolin Marinus Knobel. He also served in the Imperial Army. His initial career started as a private under Qajar Prince Abdol-Hossein Farman Farma's command. Farman Farma noted that Reza had potential and sent him to military school where he gained the rank of gunnery sergeant. In 1911, he gave a good account of himself in later campaigns and was promoted to First Lieutenant. His proficiency in handling machine guns elevated him to the rank equivalent to captain in 1912. By 1915, he was promoted to the rank of Colonel. His record of military service eventually led him to a commission as a brigadier general in the Persian Cossack Brigade. He was the last commanding officer of the Brigade, and the only Iranian commander in its history, succeeding to this position the Russian colonel Vsevolod
