Baron Yesugai Naran, called Ucla
Yesugai Naran was born in the high Altay Mountains in the spring of 1200 A.D.
His father was part of a tribe known as the Naiman, and part of a group of Naimans who sided with Temujin during a war and became part of Genghis's personal guard.
Yesugai's mother was a Nestorian Christian, and since his father was gone to war with Genghis most of the time, Yesugai was raised as such.
Yesugai grew up as a typical Mongol. He learned to ride before he could walk, use a bow and hunt. During the summer they moved up high into the mountains to escape the heat and during the winter they moved into the valleys to stay out of the winds. He helped his family tend to their goats, sheep and horses. He enjoyed a diet of boiled mutton, aaruul (dried curds), milk and yoghurt. His favorite food was marmot cooked with a stone and mutton inside. He also liked vegetables when they could be found.
When he reached the age of sixteen, he entered into the service of the Khan under General Subetai. His first campaign was against the Merkit in 1216 along the river Chu .
