Wallachia is a geographical region of modern-day Romania, as well as one of the two historical Romanian principalities that laid the foundation for the establishment of the modern Romanian state. 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.
