In 1812, the Franciscan Bulgarian Roman Catholic Bishop of Chiprovtsi decided, as a result of an epidemic in the city, to move his seat to the village of Cioplea (presently part of Bucharest). The locality was a new center for the Bulgarian community in Wallachia, but opposition from the local Orthodox hierarchy allowed the move to be completed only after 1847. Following the end of the Crimean War, the Danubian Principalities came under the supervision of several European powers, ending Russian tutelage and its "Regulamentul Organic" administration. The two countries were instead awarded "ad hoc" Divans. On November 11, 1857, on Costache Negri's proposal, Moldavia's Divan regulated an end to religious discrimination against non-Orthodox Christians, a measure which mostly benefited the resident Roman Catholics and Gregorian Armenians.
