Tahmasp I (Persian: طهماسب یکم, romanized: Ṭahmāsb or تهماسب یکم Tahmâsb; 22 February 1514 – 14 May 1576) was the second shah of Safavid Iran from 1524 until his death in 1576. He was the eldest son of Shah Ismail I and his principal consort, the Mawsillu princess Tajlu Khanum. Tahmasp ascended the throne after the death of his father on 23 May 1524. The first years of Tahmasp's reign were marked by civil wars between the Qizilbash leaders until 1532, when he asserted his authority and began an absolute monarchy. He soon faced a long-lasting war with the Ottoman Empire, which was divided into three phases. The Ottoman sultan, Suleiman the Magnificent, tried to install his own candidates on the Safavid throne. The war ended with the Peace of Amasya in 1555, with the Ottomans gaining sovereignty over Iraq, much of Kurdistan, and western Georgia. Tahmasp also had conflicts with the Uzbeks of Bukhara over Khorasan, with them repeatedly raiding Herat. In 1528, at the age of fourteen, he defeated the Uzbeks in the Battle of Jam by using artillery. Tahmasp was a patron of the arts and was an accomplished painter himself. He built a royal house of arts for painters, calligraphers and poets. Later in his reign, he came to despise poets, shunning many and exiling them to the Mughal court of India. Tahmasp is known for his religious piety and fervent zealotry for the Shia branch of Islam. He bestowed many privileges on the clergy and allowed them to participate in legal and administrative matters. In 1544 he demanded that the fugitive Mughal emperor Humayun convert to Shi'ism in return for military assistance to reclaim his throne in India. Nevertheless, Tahmasp still negotiated alliances with the Christian powers of the Republic of Venice and the Habsburg monarchy who were also rivals of the Ottoman Empire. Tahmasp's succession was disputed even before his death; after his death a civil war erupted, causing the deaths of most of the royal family. His reign, spanning nearly fifty-two years, was the longest of any Safavid ruler. While contemporary Western accounts were critical of him, modern historians recognize Tahmasp as a courageous and capable commander who preserved and expanded his father's empire. His reign marked a pivotal shift in Safavid ideological policy: he ended the Turkoman Qizilbash tribes' veneration of his father as the Messiah and instead established himself as a pious and orthodox Shia king. Tahmasp also initiated a long-term process, later continued by his successors, to diminish Qizilbash influence in Safavid politics. This was achieved by introducing a "third force" composed of Islamized Georgians and Armenians.
Name "Tahmasp" (Persian: طهماسب, romanized: Ṭahmāsb) is a New Persian name, ultimately derived from Old Iranian *ta(x)ma-aspa, meaning "having valiant horses." The name is one of the few instances of a name from the epic poem Shahnameh (The Book of Kings) being used by an Islamic-era dynasty based in Iran. In the Shahnameh, Tahmasp is the father of Zaav, the penultimate shah of the mythical Persian Pishdadian dynasty.
Background
Tahmasp was the second shah of the Safavid dynasty, a family of Kurdish origin, who were sheikhs of a Sufi tariqa (school of Sufism) known as the Safavid order and centred in Ardabil, a city in the northwestern Iran. The first sheikh of the order and eponym of the dynasty, Safi-ad-din Ardabili (d. 1334), married the daughter of Zahed Gilani (d. 1301) and became the master of his father-in-law's order, the Zahediyeh. Two of Safi-ad-Din's descendants, Shaykh Junayd (d. 1460) and his son, Shaykh Haydar (d. 1488), made the order more militant and unsuccessfully tried to expand their domain.
