Tensions remained high during the Cold War, as the Greek minority was subjected to repressive measures (along with the rest of the country's population). Although a Greek minority was recognized by the Hoxha regime, this recognition only applied to an "official minority zone" consisting of 99 villages, leaving out important areas of Greek settlement, such as Himara. People outside the official minority zone received no education in the Greek language, which was prohibited in public. The Hoxha regime also diluted the ethnic demographics of the region by relocating Greeks living there and settling in their stead Albanians from other parts of the country. Relations began to improve in the 1980s with Greece's abandonment of any territorial claims over Northern Epirus and the lifting of the official state of war between the two countries. In the post Cold War era relations have continued to improve though tensions remain over the availability of education in the Greek language outside the official minority zone, property rights, and occasional violent incidents targeting members of the Greek minority.
