Michael the Brave (Mihai Viteazul) was the Prince of Wallachia from 1593 to 1601, Prince of Moldavia in 1600, and the de facto ruler of Transylvania in 1599-1600. Known for unifying the three principalities under his rule, Michael's reign marked the first time in history that Wallachia, Moldavia, and Transylvania were united under a single leader. This achievement, although brief, has made him a legendary figure in Romanian history.

Michael's desire to free the regions from Ottoman influence led to several military campaigns against the Turks. His victories gained him recognition and support from other European powers, but also many enemies. After his assassination in 1601, the united principalities quickly fell apart. However, his efforts laid the groundwork for the modern Romanian state, and his legacy is celebrated for its impact on Romanian nationalism and identity. Michael the Brave is considered a symbol of courage, a defender of Christianity in Eastern Europe, and a key figure in the long struggle for independence and unity in Romania.
