The Mughal Empire, also known as the Gurkani Empire or Babur's Timurid Empire is a large Islamic Empire primarily based around the eastern parts of the former Timurid Empire controlling the territories of the Indian Subcontinent, established and ruled by Muslim dynasty of Chagatai Turko-Mongol origin from Central Asia. The dynasty, though Turko-Mongol, is ethnically Persianate in terms of culture.
The Mughal dynasty is the direct descendant dynasty of the Timurid dynasty. Cousin dynasties to Mughal empire are dynasties surrounding the Central Asia that are all ruled by the descendants of Timurid dynasty. Hence, as the tradition marks, the descendants of Timurid dynasties adopt 'Baig/Beg' or 'Bey' as their surname along with a dynastical suffix or prefix such as 'Mirza' in the case of Mughals and 'Beg-zada' in the case of Tatars.
