What happened
Over roughly ten years, from about 1195 to 1205, Temujin built his power through a mixture of diplomacy, generosity, and calculated force. He defeated in turn the Tatars, the Kereits of his former ally Toghril, the Naimans, and the Merkids, absorbing their warriors into his own following rather than simply destroying them, a practice that let his army grow with every victory. His break with his childhood friend and rival Jamukha, who commanded his own coalition of tribes, was one of the decisive struggles of this period. By 1205 the major rival confederations that had once made the steppe ungovernable had all been broken or absorbed.
Why it matters
This decade converted Temujin from a minor chief with a handful of followers into the unrivaled power on the steppe, setting up the 1206 kurultai that would formalize his rule and give him the title Genghis Khan. Absorbing defeated warriors instead of simply killing them gave him the manpower base that later conquests depended on.
How we know
The Secret History of the Mongols is the primary narrative for this decade of campaigns; the World History Encyclopedia's account draws on it and later Persian and Chinese chronicles.
