Two thousand functionaries of the Bavarian People's Party were rounded up by police in late June 1933, and that party, along with the national Catholic Centre Party, ceased to exist in early July. Vice Chancellor Franz von Papen meanwhile negotiated the Reichskonkordat Treaty with the Vatican, which prohibited clergy from participating in politics.[15] Kershaw wrote that the Vatican was anxious to reach agreement with the new government, despite "continuing molestation of Catholic clergy, and other outrages committed by Nazi radicals against the Church and its organisations".[16]
