After the party's victory in the 1848 March Revolution, it became power holder. The first government in the history of Hungary was formed from which the prime minister, Lajos Batthyány and five other ministers were members of the Opposition Party (Minister of Justice Ferenc Deák, Minister of the Interior Bertalan Szemere, Minister of Education József Eötvös, Minister of Finance Lajos Kossuth, Minister of Agriculture Gábor Klauzál). Two other ministers, István Széchenyi and Lázár Mészáros were independent and Pál Esterházy was a member of the Conservative Party.
