FTP, name this man who rallied the Qizilbash to become the founder and first shah of the Safavid Dynasty in Iran.  
This ruler emerged victorious in a battle at Marv, killing Muhammad Shaybani, whose skull he had made into a bejeweled drinking goblet. Early in his career, he defeated Farrukh-Yasar, who had slain his father Haidar. He appointed Shams al-Din as his vizier, even though he was a member of the rival faction of White Sheep Turks. Despite having acquired technology through alliance with the Venetians, he considered it cowardly to employ artillery in battle and instead relied on cavalry, which resulted in his greatest military defeat and the occupation of his capital Tabriz. That policy was reversed by his son Tahmasp I, who succeeded him, after he'd been crushed at the Battle of Chaldiran by the force ►of Selim the Grim in 1514.
