Ba (Ljig)
Ba is a village in the municipality of Ljig in Central Serbia. According to the 2002 census, the village has a population of 605 people. It lies under the Suvobor mountain.
In World War II, Ba was a stronghold of Serbian royalist Chetnik movement. Between 25 and 28 January 1944, Chetniks led by Draža Mihailović organized the Ba Congress in the village. That was the reason that the village was neglected by post-war Communist authorities.
