located at a distance of about 15 km from Kadapa. After the death of Ambadeva, the Kakatiya king Prataparudra II ruled until the early 14th century. Prataparudra was defeated by Muslims in the reign of Khalji emperor Alla Uddin. Later in the mid-14th century, Hindus of Vijayanagar dynasty drove the Muslims out of Warangal and subsequently Kadapa and ruled for around two centuries till they were defeated by the Gulbarga sultans. The most illustrious ruler during this time was Pemmasani Thimma Nayudu (1422 CE) who developed the region and constructed many tanks and temples here. Muslims of Golkonda conquered the region in 1594 when Mir Jumla II raided Gandikota fort and defeated Chinna Thimma Nayudu by treachery. Marathas took over the city in 1740 after defeating the Nawab of Kurnool and Cuddapah. Hyder Ali and Tipu Sultan also ruled the city (1784-1792) before it fell in the hands of Nizam by the Treaty of Seringapatam in 1792. Tipu's grandmother, Hyder Ali’s mother Fatima Fakhr-un-Nisa was the daughter of Mir Muin-ud-Din, the governor of the fort of Kadapa. Later the British took control of Kadapa District in 1800 CE. Although the town is an ancient one, it was probably extended by dilazak Neknam Khan, the Qutb Shahi commander, who called the extension as "Neknamabad". The name "Neknamabad" was used for the town for some time but slowly fell into disuse and the records of the 18th century refer to the rulers not as "Nawab of Kadapa". Except for some years in the beginning, Kadapa District was the seat of the Mayana Nawabs in the 18th century. With the British occupation of the tract in 1800 CE, it became the headquarters of one of the four subordinate collectorates under the principal collector Sir Thomas Munro. In 2004, Kadapa was recognised as a municipal corporation.
