Kurdish lawmakers on Wednesday said they would end their boycott of parliament and take their oath of office this weekend.
Selahattin Demirtas, chairman of the pro-Kurdish Peace and Democracy Party said the decision was taken to work for peace in the country.
The party led the boycott after the June parliamentary elections when some of their candidates were barred from taking their seats because of their alleged involvement in terrorist activities.
Turkey's large Kurdish minority has been long been demanding increased political recognition in the country.
Kurdish militant rebels of the outlawed Kurdistan Workers Party based in northern Iraq, meanwhile, have stepped up their attacks inside Turkey, sparking Turkish military bombing raids against their bases.
The government has blamed the PKK for an explosion last week in the capital, Ankara, that killed several people.
The United States, the European Union and Turkey consider the PKK a terrorist organization.
The PKK's took up arms in its fight for Kurdish autonomy in the region in 1984. Some 45,000 people have died in the conflict.
