Milivoje Petrović Blaznavac

Milivoje Petrović Blaznavac (; 16 May 1824 – 5 April 1873) was a Serbian general and politician who served as regent from 1868 to 1872, as well as head of government from 1872 to 1873.

Initially a police officer under the leadership of local governor Jovan Obrenović, he began his political career in 1842 during the rebellion led by Toma Vučić Perišić. Between 1842 and 1855, Blaznavac served as a confidant of Stevan Knićanin in multiple capacities, during which time he climbed the ranks of the army. He would continue his ascent with the help of Ilija Garašanin after Knićanin's death in 1855.

After Prince Milan came of age in August 1872, Blaznavac shortly served as head of government before his sudden death in April 1873. Taking advantage of the regency, Ristić promulgated a new constitution in 1869 which gave greater power to the National Assembly. This way, he outmaneuvered Blaznavac and minimized the influence of the officer corps who were loyal to him. Ristić was also successful in curbing Blaznavac's staunchly pro-Austrian foreign policy and creating deeper ties to Russia, with the goal of balancing between the two. as well as his Prime Minister in late 1872, which however turned out to be short-lived.

Personal life Blaznavac was married to Katarina Konstantinović, former fiancée of Prince Mihailo Obrenović. Blaznavac was a suitor for Katarina's hand even before Prince Mihailo began to show an interest in her. The two had a son named Vojislav Blaznavac, a cavalry Colonel.
