Firuz Shah Tughlaq (reigned 1351–1388 CE) was a ruler of the Tughlaq dynasty and one of the most prominent sultans of the Delhi Sultanate. He came to power after the death of Muhammad bin Tughlaq and is remembered for focusing on public welfare, infrastructure, and administration rather than military conquest. Though he restored some stability after a period of chaos, Firuz's reign saw the beginning of the Sultanate’s decline, with increasing provincial autonomy, weakening central control, and rising Hindu resistance in the Deccan. He practiced religious intolerance more openly than his predecessors, especially toward Hindus and Shi‘ites. After his death, the Tughlaq dynasty rapidly lost power, leading to fragmentation and eventually paving the way for Timur’s invasion in 1398.
