Galdan Boshugtu Khan

Galdan Boshugtu Khan built the last great steppe empire and was destroyed by the Kangxi emperor in person. He was a son of the Dzungar ruler, recognised as a reincarnate lama as a child and sent to Tibet, where he studied under the fifth Dalai Lama for years - an unusual education for a conqueror and one he used, since the religious authority he brought back was part of his claim. When his brother was murdered in 1670 he returned to the steppe, gave up his vows, took the khanate and the title Boshugtu, meaning blessed by heaven. He unified the western Mongols, took the oasis cities of the Tarim basin, and by the 1680s controlled the trade routes across Central Asia with an army using matchlocks and light artillery obtained through Russia. His war with the eastern Khalkha Mongols drove them to submit to the Qing for protection, which is how Outer Mongolia entered the Chinese empire. Kangxi then led three campaigns against him personally, taking artillery across the Gobi with a supply system that was the real achievement, and broke his army at Jao Modo in 1696. Galdan died the following year, deserted, possibly by his own hand. The Dzungar state survived him until 1755, when the Qianlong emperor destroyed it and its people almost entirely. The Qing account of the campaigns was written to present Kangxi as a warrior emperor and should be read that way, but the logistics were real: grain carried by camel across desert to feed tens of thousands, which is why the Dzungars could not simply retreat forever as steppe armies had always done before. Firearms and supply trains ended the strategic advantage of the steppe, and Galdan is the point where that becomes visible.
