The Wallachian Revolution of 1848 was a Romanian liberal and Romantic nationalist uprising in the Principality of Wallachia. Part of the Revolutions of 1848, and closely connected with the unsuccessful revolt in the Principality of Moldavia, it sought to overturn the administration imposed by Imperial Russian authorities under the Regulamentul Organic regime, and, through many of its leaders, demanded the abolition of boyar privilege. Led by a group of young intellectuals and officers in the Wallachian Militia, the movement succeeded in toppling the ruling Prince Gheorghe Bibescu, whom it replaced with a Provisional Government and a Regency, and in passing a series of major progressive reforms, first announced in the Proclamation of Islaz.
