In 1871, the Association for Serb Liberation and Unification was founded by members of the United Serbian Youth and other patriots from all over the Yugoslav lands. The "Association" established boards in Cetinje, Novi Sad, and Belgrade. Parallelly, the "Main Board" existed in Kragujevac. This organization was founded in 1871, and was active from the beginning of 1872. It was specially established for Šumadija to work on plans for an uprising. Kragujevac was the most sophisticated of the provincial Serbian cities, and had an intelligentsia second only to Belgrade. The city was also a center of opposition, and in the early 1870s a group of oppositionists gathered around socialist Jevrem Marković. Among notable members of the Main Board for Serb Liberation were artillerist Sava Grujić, artillerist Pavle Šafarik, officer Radomir Putnik, merchant Jaša Marković, Jevrem Marković, and others. Milivoje Blaznavac, the leader of the Serbian Regency, a legitimist and political conservatist, decidedly refused proposals and plans of the United Serbian Youth, regarding the organization's project unrealistic and impracticable; that Turkey was still strong and that Russia was against an uprising in the Balkans, and that the organization also had subversive intent against the regency. Blaznavac and Jovan Ristić were alarmed by the establishment of the revolutionary organizations in Cetinje and Belgrade. The statute of the Main Board for Serb Liberation was made in the second half of December 1871, likely after the meeting between Jevrem Marković and Blaznavac. The members of the Main Board were chosen in January 1872. In the beginning of 1872, Ljubomir Durković wrote Štatut, in which it is explained that "the Main Board for Serb Liberation was established by Serb patriots with the intention to through organized uprising destroy the Turkish lordship over the Serb lands...". The second article states that this is possible to accomplish "only when Serbia enters in the absent war" and that therefore "the uprising will inflame under the flag of Milan Obrenović IV". This is a reflection of Blaznavac's demands that he managed to impose through groups of active officers on which he had considerable influence. Further, resources for realization of the program and organizational structure of the society is specified. In January 1872, the organization sent a letter to officer Jevrem Velimirović. In 1872, Jevrem Marković with the help of local representatives part of secret local boards of the Main Board established boards in Niš and Leskovac. A local board was established in Pirot the same year as well. In April 1872 the Central Board of the organization began its project of military use for an uprising. Jevrem Marković was planned to be appointed main commander of the rebel bands in Bosnia and Herzegovina. In 1872 a revolutionary assembly was held in Novi Sad under the leadership of Svetozar Marković, the younger brother of Jevrem Marković. The organization sought to contact like-minded radicals in Romania and Greece. Their initiatives, however, did not work out. When Jovan Ristić fell out in early November 1873, new Interior MinisterAćim Čumić permitted for more freedom of press, leading the group of Liberals and leftists in Kragujevac that had earlier founded a cooperative printing venture to start a Radical newspaper. Among the founders were Grujić and Šafarik.
