Wallachia

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 (Greater Wallachia) and Oltenia (Lesser Wallachia). 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.

Wallachia began to form as a principality around the 13th century, following the gradual unification of several smaller Romanian political entities. By 1330, the state had consolidated following Basarab I's victory in the Battle of Posada against the Kingdom of Hungary, ushering in a period of relative independence. In 1417, Wallachia was forced to accept the suzerainty of the Ottoman Empire for the first time; this suzerainty lasted until the mid-19th century. However in general Wallachia was able to preserve autonomy within the Empire as well as experience interruptions to Ottoman rule brought about by local rulers such as Vlad the Impaler and Michael the Brave and later external powers such as the Polish–Lithuanian Commonwealth and the Russian Empire.

In 1859, Wallachia united with Moldavia to form the United Principalities, which adopted the name Romania in 1866 and officially became the Kingdom of Romania in 1881. Later, following the dissolution of the Austro-Hungarian Empire and the resolution of the elected representatives of Romanians in 1918, Bukovina, Transylvania and parts of Banat, Crișana, and Maramureș were allocated to the Kingdom of Romania, thereby forming the modern Romanian state.
