The abolition of slavery was carried out following a campaign by young revolutionaries who embraced the liberal ideas of the Enlightenment. The earliest law which freed a category of slaves was in March 1843, which transferred the control of the state slaves owned by the prison authority to the local authorities, leading to their sedentarizing and becoming peasants. During the Wallachian Revolution of 1848, the agenda of the Provisional Government included the emancipation ("dezrobire") of the Roma as one of the main social demands. By the 1850s the movement gained support from almost the whole of Romanian society, and the law from February 1856 emancipated all slaves to the status of taxpayers (citizens).
