Due to an uncertain incident with the Turks, Cincar Marko's family had to flee to north Serbia where they settled in Valjevo where they were engaged in trade.[3]
Cincar Marko joined the uprising against Ottomans from its very start. He fought on the River Drina, stopping incursions from Bosnia. During the siege of Šabac he was at the head of bećari („lads“, men who still had no families).[4] He took part in the Battle of Mišar (1806) and one of the battles around Loznica.[5]
That same year Miloš Obrenović made him the duke of Šabačka Posavina, with its center in the town of Šabac. This duty he performed until his death in 1822. He was buried in the old town cemetery.[7]
Cincar Marko had two sons – Konstantin “Kosta” and Milan – and a daughter, Elena. All of them took the surname Cincar-Marković after their illustrious father. Cincar Marko's grandson was General Dimitrije Cincar-Marković (1849–1903), chief of staff of the Serbian army, the Prime Minister (1902/3), senator (member of the Upper House – Senat), and his great-grandson was dr Aleksandar Cincar-Marković (1889–1947), diplomat and cabinet minister in interwar Yugoslavia.

"According to local traditions, the exoduses from Niçë and Llëngë led to the establishment of two new Vlach villages north-west of Lake Ohrid, on Mount Jablanica. First Gorna Belica (Biala di ni sus) was established, high on the unseen slopes of Jablanica, and shortly afterwards Dolna Belica (Biala di n gios/Kimpu), down in the foothills.... The close relations between Gorna and Dolna Belica and the older Vlach villages of Niçë and Llëngë (a relationship akin perhaps to that between a metropolis and its colonies) is probably attested by the intermarriage and family connections which developed among them."; pp. 468-469.
