Thomas Douglas, 5th Earl of Selkirk (1771-1820), was a Scottish nobleman known for his efforts in promoting settlement in North America. He is best remembered for establishing the Selkirk Settlement in present-day Manitoba, Canada, which aimed to provide a new home for Scottish immigrants facing hardship. Selkirk was also involved in the fur trade and played a significant role in the early development of the Hudson's Bay Company. His vision for a prosperous agricultural community contributed to the growth of the region, and his legacy continues to influence Canadian history today.
