Romanians are a Romance-speaking ethnic group and nation native to Central, Eastern, and Southeastern Europe. Romanians share a common culture, history, ancestry and language and live primarily in Romania and Moldova. There is a debate regarding the ethnic categorisation of the Moldovans, concerning whether they constitute a subgroup of the Romanians or a completely different ethnic group. The origin of the Romanians is also fiercely debated, one theory suggests that the ancestors of Romanians are the Daco-Romans, while the other theory suggests that Romanians are mainly the Thraco-Romans and Illyro-Romans from the inner Balkan Peninsula, who later migrated north of the Danube.
