The Arthashastra of Chanakya refers to it along with Vanga, Pundra and Kamarupa. This geographical idea continues with some of the ancient texts. Gauda and Vanga are sometimes used side by side. Shashanka, the first important king ofancient Bengal who is believed to have ruled between 590 AD to 625 AD, had his capital at Karnasubarna, south-west of Baharampur, headquarters of Murshidabad district. The Chinesemonk, Xuanzang travelled from the country of Karnasubarna to a region in Orissa ruled by Shashanka. There is mention of Pundravardhana being part of Gauda in certain ancient records. of the Muslim ruins of Dakhil Darwaza at Gaur, West Bengal. Evidence seems to be discrepant regarding links of Gauda with the Rarh region. While Krishna Mishra, in his Prabodha-chandrodaya, mentions that Gauda rashtra includes Rarh and Bhurishreshthika, identified with Bhurshut, in Hooghly and Howrah districts, but the Managoli inscription of the Yadava king Jaitugi I distinguishes Lala from Gaula. According to Jain writers of the thirteenth and fourteenth centuries, Gauda included Lakshmanavati in present-day Malda district. The Pala emperors were referred to as Vangapati and Gaudesvara. Sena kings also called themselves Gaudesvara. From then Gauda and Vanga seem to be interchangeable names for the whole of Bengal. In the early Muslim period the name Gauda came to be applied to Lakhanavati in Malda district. In the narrower sense Gauda is the territory between the river Padma and Bardhamana region. But in course of time it embraced much wider area. In the Satpanchasaddeshavibhaga, the seventh patala of Book III, Shaktisangama Tantra Gauda is said to have extended from the vanga country up to Bhuvanesha.
Gaur/Gour, as it is spelled mostly in modern times, refers to Lakhnauti the ruined city located on the India-Bangladesh border. Most of the former citadel is located in present-day the Malda district of West Bengal, India, while a smaller part is located in Nawabganj District of Bangladesh. This city was on the east bank of the Ganges river, 40 kilometers downstream from Rajmahal. Howeverver, the current course of the Ganges is far away from the ruins.
