Michael the Brave ( or Mihai Bravu , ; 1558 – August 9, 1601) was the Prince of Wallachia (1593–1601), of Transylvania (1599–1600), and of Moldavia (1600). He united the three principalities under a single rule for a short period of time. During his reign, which coincided with the Long War, these three principalities forming the territory of present-day Romania and the Republic of Moldova were ruled for the first time by a single Romanian leader, although the union lasted for less than six months. He is regarded as one of Romania's greatest national heroes.
