However, when tensions increased in 1963 over Cyprus, the Turkish government again invoked a ban against Greek language education, and appropriated community property held by Greeks on the island. In 1964 Turkey closed the Greek-speaking schools on the island again. Furthermore, with the 1964 Law On Land Expropriation (No 6830) the farm property of the Greeks on the island was taken away from their owners. These policies, better economic options elsewhere, presence of a larger Greek community in Greece, fear and pressure, resulted in an exodus of the Greek population from the isle. The migrants retain Turkish citizenship but their descendants are not entitled to it. Greeks who left the island in the 1960s, often sold their properties, at particularly low prices, to their Turkish neighbours, which reflected the situation of duress under which they had to leave.
