Rurik

According to tradition, Rurik sent his lieutenants Askold and Dir to raid Constantinople. While the historicity is uncertain, this event is associated with the first Rus' attack on the Byzantine Empire, highlighting early Rus' expansion.

According to the Primary Chronicle, Rurik, a Varangian chieftain, was invited by Slavic and Finnic tribes to rule over them. He established his capital at Novgorod, founding the Rurik dynasty that would rule Kievan Rus' and later the Tsardom of Russia until 1598.

Rurik consolidated his rule over Novgorod and the surrounding territories, suppressing a rebellion led by Vadim the Bold. He established a centralized authority that became the basis for the early Russian state.
