Muhammad bin Tughlaq was the Sultan of Delhi from 1325 to 1351. He is known for his ambitious and innovative policies, which included attempts to expand his empire and improve administration. However, many of his ideas were poorly executed, leading to widespread discontent and failure. One of his most notable projects was the relocation of the capital from Delhi to Dolatabad, which caused great hardship for the people. Despite his intelligence and vision, his reign is often remembered for its challenges, including economic difficulties and military setbacks, which ultimately weakened his rule.
