How did the romanov dynasty start?

The Romanov dynasty began in 1613 when Mikhail Romanov was elected Tsar of Russia by a national assembly known as the Zemsky Sobor. This followed a period of political instability and civil strife known as the Time of Troubles, which followed the death of the last Rurikid tsar, Feodor I. Mikhail's election marked the restoration of a stable monarchy, and his family ruled Russia for over three centuries until the abdication of Tsar Nicholas II in 1917 during the Russian Revolution. The Romanovs played a significant role in expanding and modernizing Russia throughout their reign.
