Chak, a Punjabi word, is the land revenue settlement/assessment circle marking a contiguous block of land. The word Chak comes from Chakar referring to a wheel in Punjabi, specifically a wheel associated with a water well. Historically there was one water well allotted per village and every village number allotted as per water-well wheel.[1] Now the individual chak circles have come to be associated with the name of the village founded within the revenue circle. Chak circles are based on the British Raj era revenue collection system. To enhance the government revenue during the British Raj, new canals were built to bring the barani (rainfed) areas under cultivation by introducing the irrigation to the bangar (upland) areas of Punjab region. Block of contiguous land irrigated by the specific Rajwaha were given a unique chak number each. The migrant farmers were brought in to settle into those newly irrigated areas around the core of new villages [which started out as dhanis]. Those new villages were called by the same name as their corresponding irrigation circle chak number. Government left it to those residents to give "chaks" a proper village name later. In due time, the term "chak" became synonymous with the term "village".[2]
Chaks are found mainly in the bagar tract on the tri-junction of Haryana, Rajasthan and Punjab region. Chak, the administrative revenue assessment circle or division, is also called the Chakla, which is not to be confused with the other types of Chaklas.[3]
