Map of Minnesota Territory, 1850, Mitchell and Cowperthwait

Only one year after the publication of this map, the United States government took possession of this native Sioux territory when the Treaty of Traverse des Sioux was signed. Dakota Sioux and Ojibwe tribes had primarily inhabited the Minnesota territory; though, the indigenous people felt compelled to sign away millions of acres of their land due to US military actions in the past. In fact, the construction of Fort Ripley was completed in 1849, which allowed the United States government to protect what they claimed to be "their" frontier land in Minnesota. Throughout the 1850s, European immigrant populations began to soar in this territory, while indigenous people ceded to their reservations. 

Samuel Augustus Mitchell (1792-1868) turned his attention to mapmaking in the 1830s, due to his dissatisfaction with available school maps. He developed a map publishing business that would make him and later his son the most prominent American map publishers of the nineteenth century. By collaborating with prominent mapmakers and engravers of the day, such as James H. Young and Henry S. Tanner, Mitchell ensured that the maps he published were of the highest quality. During the 1850s, he partnered with Thomas, Cowperthwait, & Company to publish his A New Universal Atlas and his General Atlas. In 1860, his son Samuel Augustus, Jr, joined the company and he ensured that the Mitchell name remained an important one well into the 1880s.

Thomas, Cowperthwait, and Company was founded sometime in the early 1800s by Joseph Thomas and Hulings Cowperthwait. It operated under this name until 1853. The following year the company name changed to Cowperthwait, Desilver, and Butler. However, this configuration only lasted for about a year, before it became H. Cowperthwait & Company in 1856. After 1860, it appears the company experienced several more alterations, before ceasing publication at the end of the century.
