Explanations:The Tughlaq dynasty was a significant ruling family of the Delhi Sultanate in the 14th century. The dynasty was established by Ghiyas ud din Tughlaq, who ruled from 1320 to 1325 AD. His son, Muhammad bin Tughlaq, succeeded him and ruled from 1325 to 1351 AD. Muhammad bin Tughlaq is known for his ambitious but often controversial policies, which included the transfer of the capital from Delhi to Daulatabad and the introduction of token currency.
Following Muhammad bin Tughlaq, his cousin Firuz Tughlaq ascended to the throne in 1351 AD and ruled until 1388 AD. Firuz Tughlaq's reign is marked by significant administrative reforms and public works. He was a patron of learning and the arts, and he constructed numerous canals, mosques, and other public buildings. His reign is often considered a period of stability and prosperity within the Tughlaq dynasty.
Understanding the timeline of the Tughlaq dynasty is crucial for correctly identifying the ruler of Delhi during a specific period. The question asks about the ruler from 1351 to 1388 AD, which aligns with Firuz Tughlaq's reign. Ghiyas ud din Tughlaq and Muhammad bin Tughlaq ruled before this period, and Rajab is not a known ruler of the Delhi Sultanate during this time.
It is important to note that the Tughlaq dynasty was part of the broader Delhi Sultanate, which was a significant political entity in medieval India. The dynasty's rulers played a crucial role in shaping the political and cultural landscape of the region during their reigns. Familiarity with the key figures and their contributions is essential for students preparing for competitive examinations that cover Indian history.
