Lord Rama divided, during his lifetime, his vast kingdom among his brothers and sons. His son, Kush succeeded to the south Kosala with its capital at Ayodhya. The old city of Sultanpur which lay on the right bank of the Gomti is said to have been called Kusapura or Kusabhavanpur, having been named after Kusa, who is locally believed to have founded it. Kusa appears to have extended the Aryan ideals and institutions to the Vindhya region. The story of his marriage with a Nag princess testifies that he propagated Vedic culture among aborigines. Afterwards the central power of Kosala became weak and Dirghayajna, the ruler of Ayodhya, was subdued by Bhima, one of five Pandavas in the Mahabharat War (Mahabharata, Sabhaparva). A few generations later, in the period of king Para, Ayodhya was occupied by the king Divakara of Sravasti branch, founded by Rama's second son, Lava. The District then began to be ruled over by the Kosala kings from their capital at Sravasti. The tract of river Gomti around the village Dhopap (pargana Chanda, tehsil Kadipur) is described as Dhutpap in Visnu Puran. The original town was situated on the left bank of the Gomti. It is said to have been founded by Kusa, son of Rama, and to have been named after him Kusapura or Kusabhavanpur.
This ancient city has been identified by General Cunnigham with the Kusapur mentioned by Hiuentsang, the Chinese traveller. He states that there was in his time a dilapidated stupa of Ashoka and that Buddha taught here for six months. There are Buddhist remains still visible at Mahmoodpur, a village, 8 km distant to the north-west of Sultanpur.
The town subsequently fell into the hands of Bhars, who retained it until it was taken from them by Musalmans in the 12th century. About seven hundred and fifty years ago, it is said, two brothers, Sayid Muhammad and Sayid Ala-ud-Din, horse dealer by profession, visited eastern Avadh and offered some horses for sale to Bhar Chieftains of Kusabhavanpur, who seized the horses and put the two brothers to death. This came to the ear of Ala-ud-Din Khilji, who would not allow such an outrage to pass unpunished. Gathering a mighty force, therefore, he set out for Kusabhavanpur and took revenge by killing most of the Bhars by strategem adopted after a long drawn siege. Kusabhavanpur was reduced to ashes and the town of Sultanpur, so called from the rank of the victor, rose upon its ruins.
This town was finally raised to the ground during the military operations connected with the reoccupation of the province in consequence of the inhabitants having been concerned in the murder of British officers at the outbreak of the freedom struggle of 1857. Before annexation a military station and cantonment were established on the right bank of the river in a village then known as Girghit but more commonly called by officials Sultanpur or Chhaoni Sarkar and by the rustic population Kampu or the Cam.
The present town of Sultanpur has been developed at this site. In this city there are two parks, one maintained by Soldiers', Sailers' and Airmen's board and other privately maintained known as Chimanlal Park. Alibrary called Vinayak Mehta Library Trust Association and contains over 10,000 books.
