Malik Sarwar was an eunuch of common birth, possibly a slave of African descent, in the Delhi Sultanate.
He played an important role in the accession of Muhammad Shah to the throne of Delhi, and was appointed the wazir and awarded the title of Khwaja-i-Jahan.
He later made Malik Sarwar the governor of the eastern provinces, awarding him the title of Sultan-ush-Sharq (sultan of the east).
Malik Sarwar continued to play an important role in the politics surrounding the throne, and in the accession of Mahmud Shah.
Mahmud appointed Malik Sarwar to his earlier position of the governor of the eastern provinces, and dispatched with him a large army, with twenty elephants.
