The history of the area is closely connected with the
Osek Monastery. Between 1196 and 1197,
Cistercian monks arrived from
Mašťov and founded the monastery. The monastery complex grew over time to become the economic and social hub of the region. In 1278, it was looted by Brandenburg troops. The village of Osek was founded shortly before the monastery. Until the early 14th century, the inhabitants of the village made a living mainly by cattle breeding. In the 14th century, mining of silver and tin developed. In 1421 and then again in 1429, the monastery was burned down by the
Hussites and many monks were killed. The property of the monastery was gradually dismantled, and in 1580 it was abolished by Emperor
Rudolf II. Osek was acquired by the
Prague archbishopric and the monks were forced to leave for
Zbraslav Monastery. The dissolution of the monastery was annulled in 1614 by
Pope Paul V. During the
Thirty Years' War, the Osek estate was confiscated by Protestants and sold to several buyers. In 1626, the monastery was returned to the Cistercians and began to regain its glory, which fully developed in the 18th century. The monastery was abolished in 1950 and restored in 1991. ==Demographics==
