As the Zomi lacked a formal writing system in the past, the story of Tedim mostly depends on oral tradition.
Establishment of Tedim is ascribed to Gui Mang II, a powerful prince from the then ruling Guite family in the region (c. 1600).
At the time of Mang Suum II, son of Pum Go, the allied force of the Pawihangs began their advance in the region and attacked Tedim.
