Details of The oldest country in Europe:
San Marino, which separated from Rome in 300 AD, is the oldest nation in Europe despite having a land area of only 24 square miles and a population of barely 35,000. Unlike the rest of Europe, it has maintained the same lands, the same administration, and the same form of official control since 300 AD.
