The constitution of 1960 could not function properly because Greekcypriot society(inspired by Eoka) were seeking ENOSIS CONTRARY TO WHAT HAVE BEEN SIGNED IN THE AGREEMENT OF ESTABLEMENT of the republic of Cyprus. Imagine UNDER such an environment HOW could the Turksihcypriots accept to COOPERATE with these people who rejected what they have signed in 1960 as a Independent sovereign NATION ?
ENOSIS idea begun in 1955 by the EOKA the extremist Organisations which demanded an immediate withrawal of the British Forces in Cyprus despite all Information of adverse negative consequenses this action could have!. Let me remind you that also countries like Hong Kong were also under British Control but they did not acted with stupidity and fanatism like what EOKA Did. Hong kong got his independence in 1996 and now it is considering one of the main financial serrvices provider in the world.
