Its members were mostly middle-class citizens and peasants. For a long time it was a faction of the Resolution Party and then of the Left Centre under the name of Szélsőbal.
The party participated the 1865 before becoming permanently independent in April 1868. The leaders were Ignác Helfy and Ernő Simonyi. Ignác Helfy were the leader at the time of the 1869 election, but he wasn't ever a party president. József Madarász were the leader of the party in the 1872 election. And Dániel Irányi would be the last leader of the party, who managed the merger with the Party of Independence.
