Tughlaq dynasty (c. 1320–1410 CE)

The Tughlaq dynasty's reign formally started in 1320 in Delhi when Ghazi Malik assumed the throne under the title of Ghiyath al-Din Tughluq after defeating Khusrau Khan at the Battle of Lahrawat.

During Ghazi Malik's reign, in 1321 he sent his eldest son Jauna Khan, later known as Muhammad bin Tughlaq, to Deogir to plunder the Hindu kingdoms of Arangal and Tilang (now part of Telangana). His first attempt was a failure. Four months later, Ghiyasuddin Tughlaq sent large army reinforcements for his son asking him to attempt plundering Arangal and Tilang again. This time Jauna Khan succeeded and Arangal fell, it was renamed to Sultanpur, and all plundered wealth, state treasury and captives were transferred from the captured kingdom to the Delhi Sultanate.The Muslim aristocracy in Lukhnauti (Bengal) invited Ghiyasuddin Tughlaq to extend his coup and expand eastwards into Bengal by attacking Shamsuddin Firoz Shah, which he did over 1324–1325 CE, after placing Delhi under control of his son Ulugh Khan, and then leading his army to Lukhnauti. Ghiyasuddin Tughlaq succeeded in this campaign.

After his father's death in 1325 CE, Muhammad bin Tughlaq assumed power and his rule saw the empire expand to most of the Indian subcontinent, its peak in terms of geographical reach. He attacked and plundered Malwa, Gujarat, Lakhnauti, Chittagong, Mithila and many other regions in India. His distant campaigns were expensive, although each raid and attack on non-Muslim kingdoms brought new looted wealth and ransom payments from captured people. The extended empire was difficult to retain, and rebellions became commonplace all over the Indian subcontinent. Muhammad bin Tughlaq died in March 1351 while trying to chase and punish people for rebellion and their refusal to pay taxes in Sindh and Gujarat.

After Muhammad bin Tughlaq's death, the Tughlaq empire was in a state of disarray with many regions assuming independence; it was at this point that Firuz Shah Tughlaq, Ghazi Malik's nephew, took reign. His father's name was Rajab (the younger brother of Ghazi Malik) who had the title Sipahsalar. His mother Naila was a Punjabi Bhatti princess (daughter of Rana Mal) from Dipalpur and Abohar according to the historian William Crooke. The southern states had drifted away from the Sultanate and there were rebellions in Gujarat and Sindh, while "Bengal asserted its independence." He led expeditions against Bengal in 1353 and 1358. He captured Cuttack, desecrated the Jagannath Temple, Puri, and forced Raja Gajpati of Jajnagar in Orissa to pay tribute. He also laid siege to the Kangra Fort and forced Nagarkot to pay tribute. During this time, Tatar Khan of Greater Khorasan attacked Punjab, but he was defeated and his face slashed by the sword given by Feroz Shah Tughlaq to Raja Kailas Pal who ruled the Nagarkot region in Punjab.
