It wasn’t until I visited Bulgaria that I realized what a challenging history it’s had. It lies between the River Danube (with Romania) to the north, the Black Sea to the east, Greece and Turkey to the south and Serbia and Macedonia to the west. Historically, its borders have always been under threat and, over the centuries, they have expanded and contracted. 5000 years ago, they were invaded by the Thracians who came from Asia, bringing the Bronze Age with them. The Romans, coming up from the south, staked their claim to the country in the 1st century AD. In AD 300, the Emperor Constantine moved his capital to nearby Byzantium, renamed it Constantinople and Bulgaria, inevitably, became part of his Empire. By the 9th century, Bulgaria had converted to Greek Orthodox Christianity.
