Territorial evolution of Romania information

The territorial evolution of Romania (Romanian: Evoluția teritorială a României) includes all the changes in the country's borders from its formation to the present day. The precedents of Romania as an independent state can be traced back to the 14th century, when the principalities of Moldavia and Wallachia were founded. Wallachia during its history lost several portions of its territory, either to the Ottomans or the Habsburgs. However, this land would be later essentially recovered in its entirety. Moldavia, on the other hand, suffered great territorial losses. In 1774, the Habsburgs invaded Bukovina and annexed it one year later, and in 1812, the Russian Empire took control of Bessarabia. Both territories were later exposed to powerful colonization policies. The principalities declared unification in 1859 as the Principality of Romania. This new state sought independence from the Ottoman Empire's vassalage, and in 1878, it fought a war against it alongside Russia. However, the latter would annex Southern Bessarabia, which was recovered decades before. Romania received Northern Dobruja as compensation, and would wage a war for the southern part against Bulgaria in 1913.

The now kingdom of Romania had great territorial ambitions which, once they were promised by the Entente, dragged Romania to World War I in 1916. Initially, it suffered a defeat leading to the loss of its Carpathian mountain passes and Dobruja in 1918. During this period, the union of Bessarabia with Romania was achieved. As the Central Powers weakened and pressure from the Entente (especially from France) increased, Romania reentered the war the same year. The Entente turned out to be the winner and Romania regained its lost territories after its initial defeat, as well as Bukovina and Transylvania. During this period, the country reached its maximum territorial extension, being known as Greater Romania.

However, Romania's neighbors were not satisfied with the new borders. Romania relied on regional alliances and protection from France and the United Kingdom at the west. However, soon Nazi Germany defeated France, causing great concern in the country. Since it was already apparent that the West could no longer protect Romania, the Soviet Union occupied Bessarabia, Northern Bukovina and the Hertsa region in 1940 after an ultimatum that Romania was forced to accept. The king, Carol II, was alarmed and sought the help of Germany to protect Romania's territory, but it forced the country to cede Northern Transylvania to Hungary and Southern Dobruja to Bulgaria. The king lost all his popularity, causing Ion Antonescu's rise to power. He officially joined Axis and demanded territories from Yugoslavia after its invasion, specifically Banat and the Timok Valley. This, however, never happened. In 1941, the Axis invaded the Soviet Union, allowing the recovery by Romania of its lost territories plus Transnistria, which was placed under military–civil administration. Nevertheless, this operation failed, and after the overthrow of Antonescu, Romania changed sides in 1944 and fought against the Axis, thus losing Bessarabia and Northern Bukovina once again to the Soviet Union. This made possible the recovery of Northern Transylvania by the country.

A communist government with Soviet backing was fully installed in the country in 1947. The Soviet Union had occupied several Romanian islands in the Danube Delta and the Black Sea, being this a territorial change which was made official in 1948. One of these islands was the Snake Island, which caused a dispute over the maritime borders between the now democratic Romania and Ukraine in 2009 in which Romania gained 80% of the disputed zone.

Nowadays, nationalists and other Romanian groups seek the territorial expansion of their country, especially through Bessarabia and Northern Bukovina.
