Kot derived from the Sanskrit term 'Kotta' meaning fort. The chief of the Kotta was called 'Kottapala'. Hindu-Buddhist writings, copperplate and pillar inscriptions refer to Kottapala as the head of a fort. In the local dialect the term 'Kottapala' was transformed first to 'Kotpala' and then to 'Kotala'.

Many place names in Bangladesh either begin with or end in kot, eg kotalipara of Gopalganj, Sahar Vidyakot under Gazipur, Mangalkot in Naogaon, Koterpar in Chittagong, Vardhankot in Bogra and so on. Many artefacts have been unearthed in Kotalipada and there is the least doubt about its antiquity. There exist the remains of a walled fort in Sahar Vidyakot village on the bank of the Sitalakhya. A shallow ditch externally surrounds the wall. It is gathered that at times artifacts were found there also. Kotalipada also was surrounded by high earthen wall. It can, therefore, be guessed that Kotalipada also was once a fort.

Kots were located in strategically important places. Some scholars consider the Kots to be centres of local administration in those days.
