In 1206, after having gathered all the Mongolian tribes under its authority, Gengis Khan founds the first Mongolian Empire. This one can then begin its extension. Helped of his/her sons, Gengis khan conquers China of North, Iran, the south of Russia and Afghanistan. With its death (1227), its empire is divided into four between its grandson Batu and its sons Djaghataï, Ogoday and Toluy. Those decide a new offensive and seize Korea before attacking Russia of North, the Ukraine, then Hungary.
In 1258, Hulagu, the son of Toluy, conquers the caliphate of Baghdad and Syria, but, overcoming by the Mamelukes of Egypt, it evacuates Syria, preserving Iraq and Persia. In 1279, whole China is annexed by the large Kubilay khan, which restores the unit of the country and founds the dynasty of Yuan. Strongly influenced by the culture of their subjects, the successors of Kubilay convert with Buddhism. But they lose any contact with the Mongolian world, which approached Turkish civilization. They must soon face the rising of the Chinese. In 1368, the last Mongolian emperor is driven out of Beijing.
