The events of the summer of 1974 dominate the politics on the island, as well as Greco-Turkish relations. Around 150,000 settlers from Turkey are believed to be living in the north—many of whom were forced from Turkey by the Turkish government—in violation of the Geneva Convention and various UN resolutions. Following the invasion and the capture of its northern territory by Turkish troops, the Republic of Cyprus announced that all of its ports of entry in the north were closed, as they were effectively not under its control.[citation needed]
