Wallachia or Walachia is a historical and geographical region of modern-day Romania. It is situated north of the Lower Danube and south of the Southern Carpathians. Wallachia was traditionally divided into two sections, Muntenia and Oltenia. Dobruja could sometimes be considered a third section due to its proximity and brief rule over it. Wallachia as a whole is sometimes referred to as Muntenia through identification with the larger of the two traditional sections.

Voivode, also spelled voivod, voievod or voevod and also known as vaivode, voivoda, vojvoda or wojewoda, is a title denoting a military leader or warlord in Central, Southeastern and Eastern Europe in use since the Early Middle Ages. It primarily referred to the medieval rulers of the Romanian-inhabited states and of governors and military commanders of Ukrainian Cossacks, Hungarian, Balkan, Russian people and other Slavic-speaking populations.
