Are the czars of past dynasties a family?

Not a family, because Russia is also divided into different dynasties, and the czars of each dynasty come from different families. Of course, the royal family is related by blood.

Ivan IV, a lyrical dynasty before Romanov Dynasty, began to use the title of "Tsar" in 1547.

Lulik dynasty was the first dynasty in the ancient Russian country to rule the Eastern Slavs. It is roughly equivalent to parts of eastern Europe, Ukraine and Belarus in Russia today. Kiev Ross was founded by Wali people from northern Europe and Sweden, and its leader was named Ryurik, so it was called the lyric dynasty. Since 882 AD, it has established its capital in Kiev, so it is also called Kiev Ross. 1598 After the death of fyodor Ivanovich, the last czar of the Liurik dynasty, the most important branch of this dynasty was cut off.

Peter I of Romanov Dynasty proclaimed himself emperor in order to make Europe recognize Russia as a European monarchy.

Romanov dynasty (1613-1917) was the second and last dynasty that ruled Russia, and it was also the most prosperous dynasty in Russian history. Russia has developed from an isolated small country in Eastern Europe to one of the world powers.

The famous Queen Catherine II, the wife of Peter III Fedorovici of Romanov Dynasty in Russia, is related to and descended from Ryurik Dynasty in Russia.
