A main source of tension now is the status of Moldova. The conflict over Moldova, or Bessarabia, is not new. It has been ongoing between Romania and Russia for over a century, due to Russia's strategic interests in the region conflicting with Romania's goal of a unified pan-Romanian state. Bessarabia, now known to most of the world as Moldova, was originally a region within Moldavia; Romania was forced to hand it over to Russia at the 1870s Congress of Berlin. It was briefly regained, then retaken by the Soviet Union after World War II. Romanians may view Moldova as being "stolen" by Russia. Romania regained the territory at the end of World War I, only to lose it again at the end of World War II. At the time of the fall of the Soviet Union, the Romanian language (under the controversial name of the "Moldovan language") with a Latin script was mandated as the official language of Moldova, causing conflict with non Romanian-speaking regions (namely, Gagauzia and Transnistria). However, Moldova opted against rejoining Romania at the time, claiming that it had a separate national identity (see: Moldova–Romania relations; movement for the unification of Romania and Moldova). Romanians may view Moldovans as being victims of forced Russification and brainwashing.
