A Just Russia formed on 28 October 2006 as a merger of three parties, namely Rodina, the Russian Party of Life and the Russian Pensioners' Party. Of these, the nationalist Rodina was the largest, having won 9% of the popular vote in the 2003 Duma elections. At the time of the merger, Rodina had 37 seats in the Duma. The Party of Pensioners had gained 3% of the vote, failing to cross the 5% election threshold and also been weakened by infighting in its leadership. The social-democratic Party of Life led by Sergey Mironov was still relatively young and had won only one regional election.
