The originally Italian leasing-system in which the lease was called colonia and the tenant (-farmer) colono (pi. coloni) involved only the westernmost fringes of Slovenia. It was considered to be a relation governed by civil law and combining tenancy and social contract. It was abolished in 1945 and 1947 respectively. In 1953 a research team of the Slovene Ethnographic Museum visited the Goriška Brda region and, besides other activities, gathered evidence on how the population of this region had experienced the colonia system and what it had been like according to their perception. The information then gathered on the colonia (or pars quota) leasing-system is summarized in this article.
