Macedonia is a geographical and historical region of the Balkan Peninsula in Southeast Europe. Its boundaries have changed considerably over time; however, it came to be defined as the modern geographical region by the mid-19th century. Today the region is considered to include parts of six Balkan countries: all of North Macedonia, large parts of Greece and Bulgaria, and smaller parts of Albania, Serbia, and Kosovo. It covers approximately 67,000 square kilometres (25,869 sq mi) and has a population of around five million. Greek Macedonia comprises about half of Macedonia's area and population.

North Macedonia, officially the Republic of North Macedonia, is a landlocked country in Southeast Europe. It shares land borders with Greece to the south, Albania to the west, Bulgaria to the east, Kosovo to the northwest and Serbia to the north. It constitutes approximately the northern third of the larger geographical region of Macedonia. Skopje, the capital and largest city, is home to a quarter of the country's 1.83 million people population. The majority of the residents are ethnic Macedonians, a South Slavic people. Albanians form a significant minority at around 25%, followed by Turks, Roma, Serbs, Bosniaks, Aromanians and a few other minorities.
