 Upon his return, Parchevich engaged in diplomacy with the ultimate goal of ensuring the Liberation of Bulgaria from Ottoman rule. Receiving papal support, Parchevich visited the royal courts of Europe and advocated the formation of an anti-Ottoman alliance which would drive out the Ottoman Turks from the Balkans. Parchevich was received by the courts of the Austrian Empire, the Polish – Lithuanian Commonwealth, the Republic of Venice, the principalities of Wallachia and Moldavia, and Pope Innocent X himself. There, he requested backing for an anti-Ottoman campaign which would lead to the liberation of the Balkans, and "most of all, of the great Bulgarian Empire".
