'Prince Barbak'), known by his regnal title as Ghiyāsuddīn Bārbak Shāh (Bengali: গিয়াসউদ্দীন বারবক শাহ, Persian: غياث الدين باربک شاه), was the Sultan of Bengal in 1487 and the founder of the Sultanate's Habshi dynasty.
[1] During the reign of Jalaluddin Fateh Shah of the Bengali Muslim Ilyas Shahi dynasty, some Abyssinian eunuch slaves ended up in important and influential positions in the royal court, many as paiks (palace guards).
Barbak was a eunuch and was one of the increasingly powerful of the Abyssinian palace guards, eventually being promoted to commander of the palace-guards.
[3] Shahzada Barbak took power in 1487 and started what was to become a Habshi dynasty of rulers in Bengal.
[5] His reign was short-lived, being murdered roughly in the same year as his coronation by Saifuddin Firuz Shah, an Abyssinian eunuch who was loyal to the Ilyas Shahi dynasty and was commander of the army.
