Roma, some of whom were Turkish-speaking Muslims, was still occurring. Slavery period Romani in Wallachia and Moldavia were, from their arrival in the region, enslaved, a situation which continued until the emancipations of the mid-19th century. The institution of Romani slavery also existed in Transylvania, especially in fiefdoms which had undergone a period of control by Wallachian or Moldavian princes, but the majority of Transylvanian Roma were not slaves. One child of a former Roma slave, Ștefan Răzvan, briefly achieved power in Moldavia, ruling as Voivod for part of the year 1595. The economic contribution of slavery in the Danubian principalities was immense, yet no economic compensation was ever paid to freed slaves. The current state of social and economic exclusion in Romania has its roots in the ideology and practice of slavery, and therefore its effects are still felt today. Public discussion of Roma slavery remains something of a taboo in modern Romania, no museum of Roma history exists, nor are there any monuments or memorials to slavery. Textbooks and the Romanian school curriculum either minimise this and other aspects of Roma history or exclude it entirely. Slavery in Wallachia and Moldavia The institution of slavery in Wallachia and Moldavia predated the arrival of the Roma in the region, and was at that time principally applied to groups of Tatars or Cumans resident in the territory. Although initially all the Roma were owned by princes, groups of Roma were very quickly transferred to monasteries or boyars, creating the three groups of Roma slaves; princely slaves, monastery slaves and boyar slaves. Any Gypsy without a master would automatically become a princely slave, and any foreign-born Romani passing through the prince's dominion risked being enslaved. The Tatar component of the slave population disappeared in the second half of the 15th century, fusing into the more numerous Roma population. during this period, the Roma were organised into bands composed of 30-40 families. These bands were delineated by profession and named for the nature of their economic activity, examples include gold-washers (aurari), bear-baiters (ursari), musicians (lăutari), and spoon-makers (lingurari). Slavery in the Danubian Principalities did not generally signify that Romani or Tatar slaves were forced remain on the property of their owners, most Roma remained nomadic but were tied to their owners by certain obligations. Slaves made up the lowest category of society, below the serfs, differing from the latter not in the
