Supplex Libellus Valachorum

Supplex Libellus Valachorum Transsilvaniae (Latin for Petition of the Romanians of Transylvania) is the name of two petitions sent by the leaders of the ethnic Romanians of Transylvania to the Holy Roman Emperor Leopold II, demanding equal political rights with the other ethnicities of Transylvania and a share of the Transylvanian Diet proportional to their population. The first Supplex was sent in March 1791 by Ignațiu Darabant, the Greek Catholic bishop of Oradea, to the State Council of Vienna.
