Zíá-Barní, the author of this history, and an earnest well-
Ghiyásu-d dín Balban ascended the throne in 662* H. He was one of the Shamsí slaves, and belonged to the band of Turk slaves which was known as “The Forty.” * * * Before he became king the glory of the State had greatly declined from what it had been in the days of Sultán Shamsu-d dín, who was the equal of the Sultán of Egypt, and the compeer of the kings of 'Irák, Khurásán, and Khwárizm. For thirty years after him, during the reigns of his sons, the affairs of the country had fallen into confusion through the youth and sensuality (of his immediate successors), and through the mildness and humility of Sultán Násiru-d dín. The treasury was empty, and the royal court had but little in the way of wealth and horses. The Shamsí slaves had become Kháns, and divided among them the wealth and power of the kingdom, so that the country was under their control.
During the ten years after the death of Sultán Shamsu-d dín four of his children sat upon the throne. They were young and unequal to the duties of government. Their lives were passed in pleasure and neglect of their duties. The Turk slaves, called “The Forty,” thus obtained power in the government of the country, and grew in strength and dignity. The free-born maliks and noble officials who had served the Shamsí throne with honour and renown were all removed.
