On 22 December 1995, Ottó Stekler (husband of fellow politician Mária Seres) and his followers left the Green Party of Hungary (MZP) to form the MSZZP in Nyíregyháza.

In the 1998 parliamentary election, the MSZZP was able to set up a regional list in Szabolcs-Szatmár-Bereg County and obtained the 0.05 percent of votes, thus won no seats.

Previously the party activists also tried to disturb the campaign speech of Gábor Demszky, the Mayor of Budapest, by throwing a cake at his face.

The MSZZP also released a video record which claimed system-wide counterfeiting of proposal coupons took place at the Hungarian Socialist Party (MSZP) headquarters.

Protesting against the electoral system, MSZZP activists burned their proposal coupons in front of the Hungarian Parliament Building.
