Kerman (Persian: كرمان‎, also Romanized as Kermān, Kermun, and Kirman; also known as Carmania) is the capital city of Kerman Province, Iran. At the 2011 census, its population was 821,374, in 221,389 households, making it the 10th most populous city of Iran.
It is the largest and most developed city in the Kerman Province and the most important city in South-East Iran. It is one of the largest cities of Iran in terms of area. Kerman is famous for its long history and strong cultural heritage. The city is home to many historic mosques and Zoroastrian fire temples. Kerman is also on the list of the recent world's 1000 cleanest cities. Kerman is also a former capital of Iran, a position that it held during several periods. It is located on a large, flat plain, 1,036 km (643 mi) south of Tehran, the capital of Iran.
Kerman was founded as a defensive outpost, with the name Behdesīr, by Ardeshir I, founder of the Sassanid Empire, in the 3rd century AD. After the Battle of Nahāvand in 642, the city came under Muslim rule. At first the city's isolation allowed Kharijites and Zoroastrians to thrive there, but the Kharijites were wiped out in 698, and the population was mostly Muslim by 725. Already in the eighth century the city was famous for its manufacture of cashmere wool shawls and other textiles. The Abbasid Caliphate's authority over the region was weak, and power passed in the tenth century to the Buyid dynasty, which maintained control even when the region and city fell to Mahmud of Ghazna in the late tenth century. The name Kerman was adopted at some point in the tenth century.
Kerman was under the Seljuk Turks in the 11th and 12th centuries, but remained virtually independent, conquering Oman and Fars. When Marco Polo visited the city in 1271 it had become a major trade emporium linking the Persian Gulf with Khorasan and Central Asia. Subsequently, however, the city was sacked many times by various invaders. Kerman expanded rapidly during the Safavid Dynasty. Carpets and rugs were exported to England and Germany during this period.
In 1793 Lotf Ali Khan defeated the Qajars and in 1794 captured Kerman. But soon, he was besieged in Kerman for six months by Agha Mohammad Khan. When the city fell to Agha Mohammad Khan, angered by the popular support that Lotf Ali Khan had received, all the male inhabitants were killed or blinded, and a pile was made out of 20,000 detached eyeballs and poured in front of the victorious Agha Muhammad Khan. The women and children were sold into slavery, and the city was destroyed over ninety days.
The present city of Kerman was rebuilt in the 19th century to the northwest of the old city, but the city did not recover to its former size until the 20th century.

Abū Saʿīd Mirza (Chagatay/Persian: ابو سعید میرزا‎) was the son of Muḥammad son of Miran Shah son of Amir Timur (Herat, 1424–1469), and was a Timurid Empire ruler in Transoxiana, Khurasan and the southern Caspian region, what is today parts of Turkmenistan, Kazakhstan, Uzbekistan, Iran, Azerbaijan and Afghanistan and member of the Timurid dynasty.
Abū Saʿīd was the great-grandson of Timur, the grandson of Miran Shah, and the nephew of Ulugh Beg. He was the grandfather of Babur, by his son Umar Sheikh Mirza, the founder of the Mughal Empire in South Asia. As a young man his ancestry made him a principal in the century-long struggle for the remnants of Timur's empire waged between Timur's descendants, the Black Sheep Turkomans, and the White Sheep Turkomans (1405–1510).

He raised an army but failed to gain a foothold in Samarkand or Bukhara (1448–1449); established his base at Yasi and conquered much of Turkestan in 1450. In June 1451, he captured Samarkand with the aid of the Uzbek Turks under Abūl-Khayr Khān, thus securing rulership of the eastern part of Timur's Empire, Transoxiana. He fought an inconclusive war with Mirza Abul-Qasim Babur bin Baysonqor of Khorasan in 1454; and took advantage of his cousin Jahan Shah's capture of Herat late in 1457 to capture it for himself in 1458, thus acquiring the rest of Timur's heartland and becoming the most powerful of the Timurid princes in central Asia. He defeated an alliance of three other Timurid princes at the Battle of Sarakhs in March 1459, and conquered eastern Iran and most of Afghanistan by 1461, agreeing with Jahan Shah to divide Iran between them; when the White Sheep Turkoman chieftain Uzun Hasan attacked and killed Jahan Shah, Abu Sa'id spurned Uzun Hasan's peace offer and answered Jahan Shah's son's request for aid.

Captured (on 11 February 1469 [NS]) by Uzun Hasan with a small force at the calamitous Battle of Qarabagh (in modern Republic of Azerbaijan) during a campaign against the Ak Koyunlu (White Sheep) Turkomans, he was handed over to Yadgar Muhammad Mirza on 17 February 1469, who executed him, ostensibly in retribution for Abū Sa'id's execution of Yadgar Muhammad Mirza's grandmother Gawhar Shad, who had been intriguing against him.
