Born March 23, 1964, in Dunaevtsy, Ukrainian SSR, Soviet Union, he studied in Riga on the history faculty, and then in the Moscow Institute of Jurisprudence.

The following year his ambitions of party leadership led him into conflict with the communist leader Gennady Zyuganov.

Semigin made several attempts to seize power from Zyuganov, including organisation of separate CPRF congress.

In the Duma, Semigin moved to the Rodina faction, and at the same time founded his own party Patriots of Russia.
