Map - Municipality of Tolmin (Občina Tolmin)

The Municipality of Tolmin (Občina Tolmin) is a municipality in northwestern Slovenia. Its seat and largest settlement is Tolmin.

In ancient times the area was inhabited by the Illyrians and then by the Romans. In the 6th century the Slavs, ancestors of present-day Slovenes, settled the area.

Until 1420 it belonged to the Patriarchate of Aquileia, when it was acquired by the Republic of Venice. In 1514 it became a possession of the Habsburgs, who gave it as fief to the Coronini-Cronberg family. Medieval documents testify to a long series of uprisings, culminating in the Tolmin peasant revolt of 1713. That particular insurgence spread from Tolmin County to the Vipava Valley, Karst, and Brda, and further on to northern Istria. The uprising was mercilessly crushed by the imperial army and its eleven leaders were beheaded.

In the 16th century, the area became part of the County of Gorizia and Gradisca. During the World War I, Tolmin served as a base for the victorious breach of the Soča/Isonzo Front. Occupied by Italian troops at the end of 1918, it was part of the Kingdom of Italy between 1918 and 1943 (nominally to 1947) as a commune of the Province of Gorizia (as Tolmino), except during the period between 1924 and 1927, when the Province of Gorizia was abolished and annexed to the Province of Udine. and between 1943 and 1945 of the Nazi German Operational Zone Adriatic Coast. In 1945 it was liberated by the Yugoslav Partisans and in 1947 it was officially annexed to Yugoslavia. Since then, it has been an integral part of Slovenia.
