All digression-
Indians already on the rez; not involved in the homestead lands. This period of unrest and KKK was 1930-1939 (Alberta Homestead lands were opened 1905, and some were taken up as late as 1950s by veterans under an act of 1942). At this time payment was required but it was term and very low.
The railroads and government brought in a large number of Ukrainians in the 1920s and 1930s to homestead but the first Ukrainians and Poles came about 1900, some in groups. The region around Edmonton and north and east was often called "Little Ukraine" and is noted for its onion dome Orthodox churches.

The first colony of Blacks in Alberta came about 1916, mostly from Tulsa, OK area, and settled at Amber Valley-Pine Valley, Alberta. A few have remained and there is a small museum. A few individuals came, perhaps the best known is a cowboy, later rancher, John Ware.
Since 1950, Jamaicans, Africans, etc. have come to the cities, no organized opposition, and have integrated well.
