In 1991, since Turkey's election system had two large election thresholds post-1980 (10% nationwide and 15% local thresholds) and since the centre-left was divided into two parties (SHP and DSP), social democrats and democratic left groups had little power in parliament. Between 1991 and 1995, Turkey was ruled by the coalition of centre-right DYP and center-left SHP (later, the SHP joined the CHP). The Islamists returned with a new party, the Welfare Party (Refah), while the nationalist MHP took advantage of the disillusionment felt by former supporters of the Refah Party and the constant bickering of ANAP and DYP.
