Some Roma may have been slaves of the Mongols or the Tatars, or they may have served as auxiliary troops in the Mongol or Tatar armies. However, most of them migrated from south of the Danube at the end of the 14th century, some time after the founding of Wallachia. By then, the institution of slavery was already established in Moldavia and it was possibly established in both principalities. After the Roma migrated into the area, slavery became a widespread practice among the majority of the population. The Tatar slaves, smaller in numbers, were eventually merged into the Romani population.
