On the death of Fíroz Sháh III., the king's servants seated his grandson, Ghiásu-d-dín, on the throne, and gave him the title of Fíroz Sháh IV. He was the son of the prince Fat'h Khán; and, being quite a youth, became addicted to indolence, giving himself up to pleasure and sensual amusements. As the people consequently suffered oppression, Malik Ruknu-d-dín, the Viceroy, put him to death, in A. Hij. 791, A.D. 1387, and hung up his head in front of the darbár. His reign lasted six months and five days.*
