Abbas the Great

Abbas I (Persian: عباس یکم, romanized: Abbâs-e Yekom; 27 January 1571 – 19 January 1629), commonly known as Abbas the Great (Persian: عباس بزرگ, romanized: Abbâs-e Bozorg), was the fifth Safavid shah of Iran from 1588 to 1629. The third son of Shah Mohammad Khodabanda, he is generally considered one of the most important rulers in Iranian history and the greatest ruler of the Safavid dynasty.

Although Abbas would reign over Safavid Iran at its military, political and economic height, he came to the throne during a period of instability in the empire. Under the ineffective rule of his father, the country was riven with discord between the different factions of the Qizilbash army, who killed Abbas' mother and elder brother. Meanwhile, Iran's main enemies, its archrival, the Ottoman Empire, and the Uzbeks, exploited this political chaos to seize territory for themselves. In 1588, one of the Qizilbash leaders, Murshid Quli Khan, overthrew Shah Mohammed in a coup and placed the 16-year-old Abbas on the throne. However, Abbas soon seized power for himself.

Under his leadership, Iran developed the gholam system where thousands of Circassian, Georgian, and Armenian slave-soldiers joined the civil administration and the military, thus creating a new strata in Iranian society, this was initiated by his predecessors but significantly expanded during his rule. This allowed Abbas to eclipse the power of the Qizilbash in the civil administration, the royal house, and the military. These actions, as well as his reforms of the Iranian army, enabled him to fight the Ottomans and Uzbeks and reconquer Iran's lost provinces, including Kakheti, whose people he subjected to widescale massacres and deportations. By the end of the 1603–1618 Ottoman War, Abbas had regained possession over South Caucasus and Dagestan, as well as swaths of Western Armenia and Mesopotamia. He also took back land from the Portuguese and the Mughals and expanded Iranian rule and influence in the North Caucasus, beyond the traditional territories of Dagestan.

Abbas was a great builder and moved the empire's capital from Qazvin to Isfahan, and transformed the city into a masterpiece of Safavid architecture. In his later years, following a court intrigue involving several leading Circassians, Abbas became suspicious of his own sons and had them killed or blinded.
