Bosnia and Herzegovina
Stećci are monumental medieval tombstones found primarily in Bosnia and Herzegovina, but also in Croatia, Serbia, and Montenegro. They’re enormous - some of them weigh as much as 30,000 kg (about 73,000 lbs), and are carved with motifs and symbols (such as farmers, warriors, dancers, suns, crosses, and trees) that are not well-understood today. Inscriptions were made in Bosnian Cyrillic.
The Bogomils were a sect of religious dualists who practiced in Bosnia and Herzegovina between the 10th and the 14th centuries. They were mostly peasants and had a wide peasant following. They denounce wealth, they have a horror of the Tsar, they ridicule their superiors, condemn the nobles and forbid all slaves to obey their masters. — COSMAS THE PRIEST Against the Bogomils Source: komarna.co.uk
