 Prince Milan, together with his Foreign Minister Čedomilj Mijatović, formalized his relations with Vienna, by preparing and signing the "Secret Convention" in 1881, a document unknown both to the Serbian parliament and the wider public, that put Serbian foreign policy under Austrian tutelage.This was a major point of disagreement between the Prince and his Prime Minister, and in order to avoid any further lack of loyalty from Čedomilj Mijatović, Piroćanac took the office of Foreign Minister to himself, leaving Mijatović solely the post of finance minister.Nevertheless, Mijatović provoked another scandal, during the bankruptcy of l’Union Générale from Paris, by granting them consent to realize a set of state bonds for the railway loan.
