Rurik

Rurik arrived in Novgorod in 862, summoned by tradition to bring order where local rule had failed. He reigned until his death in 879, leaving behind an infant son, Igor, and a kinsman, Oleg, to serve as regent. That moment of succession set in motion the Rurik dynasty, which would govern Kievan Rus' and its scattered principalities, then the Tsardom of Russia itself, until Feodor I died in 1598. The line stretched across more than 700 years, making this Varangian chieftain the root of the Russian monarchy—a founder not by blood spilled but by an invitation extended.
