Parts of the land that is today known as Russia was populated by various East Slavic peoples from before the 9th century. The first states to exert hegemony over the region were those of the Rus' people, a branch of Nordic Varangians who entered the region occupied by modern Russia sometime in the ninth century, and set up a series of states starting with the Rus' Khaganate circa 830. Little is known of the Rus' Khaganate beyond its existence, including the extent of its territory or any reliable list of its khagans (rulers).
