Christian Community of Universal Brotherhood (CCUB) (Russian: Христианская Община Всемирного Братства) was the main spiritual and economic organization of Canadian Doukhobors from the early 20th century until its bankruptcy in 1938. In its corporate form, it was an instrument that allowed its followers, known as Community Doukhobors, to have a form of collective ownership of the lands that they lived and worked on, as well as of agricultural and industrial facilities.
The name of the Christians of the Universal Brotherhood was used by the Doukhobors to describe themselves even before they left Russian Empire in 1899. It appears, for example, in Leo Tolstoy's article (April 1898).
Once in Canada, the Doukhobor immigrants started to use the name of The Christian Community of Universal Brotherhood to identify themselves as a group even before the group leader Peter Verigin joined them in the late 1902.
Throughout the years, the name appeared to be attached to the overall social and economic organization of the Community Doukhobors (i.e., those who owned land and other means of production as a community). It became the official name of the organization when it was officially incorporated in 1917, and remained in use until its bankruptcy in 1937 and the following liquidation.
When several thousand Doukhobors refugees arrived to Saskatchewan from Russian Transcaucasian provinces in 1899, the main issue facing this largely peasant community was, what form of settlement, land ownership, and overall economic organization to choose. At one end of the range of possibilities, the settlers could become individual homesteaders, each family living on and farming its allotment of 160 acres (0.65 km2), as envisioned in Dominion Lands Act and encouraged by the Canadian authorities. At the other end of the range, people could live in multi-family villages, collectively owning their amalgamated land grants and other resources, and just as collectively working on them and owning the fruits of their work, as was later practiced e.g. in kibbutzim. There were, of course, also many intermediate options - as, e.g. in a typical 19th century Russian peasant community, where land was owned collectively, but partitioned (and regularly repartitioned) among families for individual farming.
