From the Introduction: "The Republic of North Macedonia is a small, landlocked country in southeastern Europe. [...] As of March 27, 2020, it is the newest member of NATO. Formerly one of Yugoslavia's six constituent republics, North Macedonia became independent in 1991 and largely avoided the violence that devastated other parts of the region. Its multiethnic population includes Slavic Macedonians (estimated to comprise about 65% of the population, although precise figures are disputed) and Albanians (an estimated 25%), as well as Turkish, Roma, Serb, Bosniak, and other minority groups. The country embraced a Euro-Atlantic foreign policy orientation early on and became the regional front-runner for membership in the European Union (EU) and NATO. By the 2000s, however, North Macedonia's Euro-Atlantic integration had lagged due to a seemingly intractable bilateral dispute with neighboring Greece (an EU and NATO member) over use of the name 'Macedonia.' Some analysts contend that North Macedonia's loss of a clear EU and NATO membership perspective contributed to a period of reform drift and democratic backsliding that began in the late 2000s and culminated in a protracted political crisis from 2015 to 2017."
