along a route that became known as the Cherokee Trail. The area of county was officially opened to white settlement following negotiations with the Cheyenne and Arapaho in the 1858 Treaty of Fort Laramie, by which time the area was part of the Nebraska Territory. The first U.S. settlers arrived that same year in a party led by Antoine Janis from Fort Laramie. Janis, who had visited the area near Bellvue in 1844 and proclaimed it "the most beautiful place on earth", returned to file his official claim and helped found the first U.S. settlement in present-day Colorado, called Colona, just west of Laporte. Nearly simultaneously, Mariano Medina established Fort Namaqua along the Big Thompson River just west of present-day Loveland. The first irrigation canals were established along the Poudre in the 1860s. In 1862 the settlement established by Janis became a

established an outpost near Laporte that was designated as Camp Collins. A devastating flood in June 1864 wiped out the outpost, forcing the Army to seek a better location. At the urging of Joseph Mason, who had settled along the Poudre in 1860, the Army relocated its post downstream adjacent to Mason's land along the Overland stage route. The site of the new post became the nucleus of the town of Fort Collins, incorporated in 1873 after the withdrawal of the Army. By that time, Mason and others had convinced the Colorado Territorial Legislature to designate the new town as the county seat. In 1870, the legislature designated Fort Collins as the location of the state agricultural college (later

), although the institution would exist only on paper for another 9 years while local residents sought money to construct the first campus buildings. In 1873, Robert A. Cameron and other members of the Greeley Colony established the Fort Collins Agricultural Colony, which greatly expanded the grid plan and population of Fort Collins.


Railroads

One of the primary goals of the early citizens of the county was the courting of

The first railroad finally arrived in the county in 1877 when the Colorado Central Railroad extended a line north from Golden via Longmont to Cheyenne. The town council of Fort Collins designated right-of-way through the center of town (and through the campus of the unbuilt college) for the line, creating a contentious issue to this day.

Agriculture

The early growth of agriculture, which depended highly on direct river irrigation, experienced a second boom in 1902 with the introduction of the cultivation of

In the following decade, the sugar beet industry brought large numbers of German emigrants from the Russian Empire to the county. The neighborhoods of Fort Collins northeast of the Poudre were constructed largely to house these new families. A significant increase in the agricultural productivity of the region came in the 1930s with the construction of the Colorado Big Thompson Project following the

Politics

Larimer was long a Republican stronghold. Between 1920 and 2004, the only Democratic presidential candidate to win a majority of votes in the county was Lyndon Johnson in 1964. However, increasing urbanization, as well as the influence of Colorado State University, caused the Republican margins to decline steadily in the 1990s and early 2000s. In 2008,
