Traces of prehistoric settlements have been found in the Cadore area and it is assumed that the first settlements were established between the VI and VII centuries by populations from the Val Pusteria, that sheltered here to avoid the barbarian invasions. In the XIII century, a particular subdivision and land management was implemented, the "Regole" (rules), which, in turn, entrusted to the head of each village a period of decisions. In the XIII century, the local authorities imposed a series of "regole" (a regulation of the lands), later cancelled by Napoleon, while in the XV century the area submitted the domain of the Serenissima Republic of Venice. After a short period of Napoleonic government and Austrian domain, the Cadore area was annexed to the Kingdom of Italy.
