How can you ignore obvious facts? It was GC leadership trying to change the basic properties of the republic.
Whilst Turkey was busy trying to undermine it!
And as for you other question:
The period from 21 December 1963 to 10 August 1964 was the most violent phase of the Cypriot conflict. Both communities estimate that several hundred of their members were wounded. In addition, several hundred were kidnapped and temporarily held hostage until exchanges were arranged. Official records show that 191 Turk-Cypriots were known to have been killed and 173 are still missing and now presumed dead. On the Greek-Cypriot side, 133 are known to have been killed and 41 are still missing and presumed dead. It is probable, however, that the figures for Turkish-Cypriot deaths include some who were killed accidentally by their own hand or by other Turk-Cypriots. Greek-Cypriot deaths are probably understated. There are indications that some casualties, for propaganda reasons, were never publicly announced. Also, casualties among Greek Army soldiers in Cyprus are not included in the Cyprus Government's figures. It may be more prudent therefore to accept that approximately 350 Turk-Cypriots were killed in this period while about 200 Greek-Cypriots and mainland Greeks were killed.
And that is just the 63-64 period where the violence was at its worst.
