Mahabad (, ), also Romanized as Mihābād and Muhābād and formerly known as Savojbolagh, is a city and capital of Mahabad County, West Azerbaijan Province, Iran. At the 2006 census, its population was 168,000 in 31,000 families. The city lies south of Lake Urmia in a narrow valley 1,300 metres above sea level. Name Mahabad first became the name of the city after World War I, during the reign of the Pahlavi shah (king) Reza Shah (). Before that, it was known as Savojbolagh, a Persian corruption of the Turkic word soghuk bulak (meaning "cold spring"). The Kurdish version was Sablagh. History Savojbolagh is first attested in the 16th century, during the Safavid era. Mukri Kurds participated in several wars between Safavid dynasty and Ottoman Empire, and gained more predominance. In 17th century AD, Savojbolagh became the seat of Mukri principality (known as Mukriyān in Sorani Kurdish and Mokriyān in Persian). Many believe Budaq Sultan Mukri, who built Savojbolagh's congregational mosque is the founder of the current town. Republic of Mahabad Mahabad was the capital of the short-lived Republic of Mahabad, which was declared independent on January 1, 1946 under the leadership of Kurdish nationalist Qazi Muhammad. The republic received strong support from the Soviet Union, which occupied Iran during the same era. It included the majority Kurdish-speaking towns of Bukan, Piranshahr, Sardasht and Oshnavieh. After an agreement brokered by the United States, the Soviets agreed to leave Iran, and sovereignty was restored to the Shah in 1947. The Shah ordered an invasion of the Republic of Mahabad shortly afterwards, the leaders of the republic including Qazi Muhammad were arrested and executed. Qazi Muhammad was hanged on 31 March 1947. At the behest of Archibald Roosevelt Jr., who argued that Qazi had been forced to work with the Soviets out of expediency, U.S. ambassador to Iran George V. Allen urged the Shah not to execute Qazi or his brother, only to be reassured: "Are you afraid I'm going to have them shot? If so, you can rest your mind. I am not." Roosevelt later recounted that the order to have the Qazis killed was likely issued "as soon as our ambassador had closed the door behind him," adding with regard to the Shah: "I never was one of his admirers."
