Two parties closed pre-1963

When Turkey entered the multi-party phase after 1950, the Nation Party (Millet Partisi), which was then formed, was clsoed by the Ankara Criminal Court of First Instance in 1954. Another party, the Democrat Party (DP), was closed by the Ankara Civil Court of First Instance after the government was overturned by the army on 27 May 1960.

And those that were not closed down...
