Wallachian officials adopted the Regulamentul Organic, which engendered a period of reforms that provided for the westernization of the local society.

Wallachia or Walachia is a historical and geographical region of modern-day Romania. It is situated north of the Lower Danube and south of the Southern Carpathians. Wallachia was traditionally divided into two sections, Muntenia and Oltenia. Dobruja could sometimes be considered a third section due to its proximity and brief rule over it. Wallachia as a whole is sometimes referred to as Muntenia through identification with the larger of the two traditional sections.

Regulamentul Organic was a quasi-constitutional organic law enforced in 1831–1832 by the Imperial Russian authorities in Moldavia and Wallachia. The document partially confirmed the traditional government, including rule by the hospodars, and set up a common Russian protectorate which lasted until 1854. The Regulament itself remained in force until 1858. Conservative in its scope, it also engendered a period of unprecedented reforms which provided a setting for the Westernization of the local society. The Regulament offered the two Principalities their first common system of government.
