The province of Assam was invaded about 1224 A.D., by a band of Ahoom or Shan adventurers; who conquered the country, parcelled out its territory, and subjected the population to a vassalage approximating to that in force under the feudal system of Europe. By this arrangement the whole body of cultivators were divided into different portions, called Khels, varying from one thousand to five thousand cultivators each. They were governed by officers of various grades: those called Borahs, possessing authority over twenty ghoots or sixty paicks; Sykeahs, over one hundred ghoots or three hundred paicks; and Huzarees, over one thousand; with one superior officer denominated a Kheldar, who was generally a nobleman, or person connected with the royal family. But in recent times this arrangement has been modified, and Borahs, Sykeahs, and Hazarees have exercised authority over a much smaller number of persons. The Kheldars collected the revenue and exercised jurisdiction in petty criminal offences. Owing to the backward state of society in Assam, and its almost utter destitution of commerce and manufactures, the revenue was seldom paid in money, but mostly in personal labour: all public buildings, roads, bridges, &c., were constructed out of the funds of labour at the command of the Government; and the services of all public functionaries, clerical, medical, military, and judicial, were paid in the same manner. To facilitate this arrangement, the community were divided into threes, (or in some parts of Assam fours) each division being called a ghote; and if one of the three served the state throughout the year, the other two were excused the payment of money, revenue, or produce. From artisans and manufacturers, who were subjected to a higher taxation than other classes, money was taken occasionally; but more frequently the tax was levied in produce.
