North Macedonia
The Ottoman Empire was originally a small city-state in Turkey. The city-state grew, and it invaded Adrianople in 1354. From there, it expanded and took over Turkey. Constantinople, the capital of the Byzantine Empire, did not get invaded by the Ottomans until 1453. After the Battle of the Maritsa River, the Ottomans conquered southern Serbia and Macedonia. Macedonia was under Ottoman Rule until 1913.
