The commune consists of 6,600 inhabitants living in two villages: Bystra and Sidzina. The foundation of the former settlement is not very well documented, whereas the latter was founded in 1563 by king Sigismund August. In 1655 the peasants of Sidzina received official letter of gratitude from king John Casimir for their victory in the local battle against the Swedish military unit. The village witnessed numerous acts of heroism (partisans) and tragedies (pacifications) during the Second World War.
