Jovović was born in Kosić near Danilovgrad in today's Montenegro. During World War II he fought for the Yugoslav Army in the Fatherland, and was a member of the Bjelopavlić Chetnik brigade. At the time when World War II started, he was serving in Strumica, near the Yugoslav border with Greece. For his part in the April War he was honoured with a medal. When the war was over, he came back to his birthplace, Kosić in Bjelopavlići. As of July 1941 he took part in antifascist war against Italy. With Kosić's Partisan unit he participated in the battle of Pljevlja, and later commanded that unit. He later fought for the Chetniks, under the command of Bajo Stanišić. As of September 1944, he was part of the delegation led by Dušan Vlahović and Jakov Jovović, that was sent from Kotor across the Adriatic Sea to Taranto to negotiate with the British. There they were informed about Allied change of support in favor of Partisans as a result of the Tehran Conference and stayed in Italy throughout the remainder of the war. Jovović spent his time in Italy in several immigration camps. He was surrounded by the people tied to the intelligence service operations. On one such occasion, he met Randolph Churchill, of whom he reportedly did not hold a very high opinion.
At that time, he found out that the Catholic Church had been hiding Ante Pavelić inside the Vatican under a false name. Jovović conceived the idea of finding and executing Pavelić due to the persecution and genocide of Serbs under his rule. Jovović was known as the founder of the Serbian Orthodox community “Saint Sava”, and one of the founders of the Organisation of Fighters “Draža Mihailović” as well as the member of the Board of the “Njegoš” association. While living in Argentina and running a successful hotel enterprise that he owned, he received tips about Pavelić's whereabouts in Argentina. Jakov Jovović began the assassination plans, but Blagoje himself agreed to carry them out. In this, they were joined by Milo Krivokapić. The assassination was scheduled to take place on April 9, 1957, on the eve of the Independent State of Croatia's anniversary celebration, but they decided to delay the attack by a day. On April 10, at 9 PMlocal time, 16 years after the founding of the Independent State of Croatia, Pavelić suspected someone was following him as he walked down a street, so he turned back and fired several shots towards Jovović, who started running after Pavelić and fired five shots, two of which hit Pavelić who then, according to Jovović, staggered, bent and begged for mercy. The assassination attempt is described in detail by Jovović in the following excerpt from the book “Two Bullets for Pavelić” : Pavelić never fully recovered from the sustained injuries. He was also suffering from diabetes and he finally died on 28 December 1959 in Madrid, Spain.
