1960 Turkish coup d'état
Some of the discontent came after 1954 and the government's response to the economic situation,  inflation was raising and there was an economic deficit. Instead of responding to the economic crisis the DP faced this situation with repression. For that reason their popularity started declining, which could be seen in the 1957 elections. As the DP witnessed their popularity dwindle, they began oppressing the opposition, mainly the RPP who had once again become their most influential opponent.
