place searching for the right capital, leaving behind his representative at each stage to rule the colonized land. Then he went up the Burhidihing river and established a province at Lakhen Telsa. Then he came back down the river and established his rule at Tipam. In 1236 he moved to Mungklang (Abhoipur), and in 1240 down the Brahmaputra to Habung (Dhemaji). In 1244 he went further down to Ligirigaon (Song-Tak), a few miles from present-day Nazira, and in 1246 to Simaluguri (Tun Nyeu), a place downstream from the present-day Simaluguri. Finally in 1253 he built himself his capital city at Charaideo near present-day Sibsagar town. The capital of the Ahom kingdom changed many times after this, but Charaideo remained the symbolic center of Ahom rule. With the help of local recruits, he established three large farms for sali rice cultivation, called Barakhowakhat, Engerakhat and Gachikalakhat''. In 1268 Sukaphaa died. At the time of his death, his kingdom was bounded by the Brahmaputra River in the west, the Disang River in the north, the Dikhow River () in the south and the Naga Hills in the east. Even though Sukaphaa treated the people of the Patkai hills very severely on his way to the Brahmaputra valley, his approach to the population in Assam was conciliatory and non-confrontational. He married the daughters of Badaucha, the Moran Chief and Thakumatha, the Barahi chief and established cordial relations with them. As he began establishing his domain, he avoided regions that were heavily populated. He encouraged his soldiers as well as members of the Ahom elite to marry locally. A process of Ahomisation (whereby locals who adopted Ahom methods of wet rice cultivation and statecraft were accepted into the Ahom fold) bolstered the process of integration. The local Borahi and the Moran people, speakers of Tibeto-Burman languages, addressed Sukaphaa's people as "Ha-Cham", that later on developed into "Assam" or "Ahom" (see Etymology of Assam), the name of the kingdom; and "Ahom", the name of the people. Memorial December 2, Assam celebrates as the Sukaphaa Divas, or Asom Divas (Assam Day). An award is given by State Govt. that day to a prominent personality.
