, Kickapoo, and Tonkawa. Several Native American sites have been found, including around Lavon Lake and Sister Grove Creek. Both the county and the county seat were named after Collin McKinney (1766-1861), one of the five men who drafted the Texas Declaration of Independence and the oldest of the 59 men who signed it.


Civil War

Like many counties in North Texas, Collin County voted against secession from the United States. This is mainly due to the relatively weak hold of slavery in Collin County and the influence of James W. Throckmorton, who had represented Collin County in both the Texas Senate and the Texas House of Representatives. Nonetheless, Collin County sent men to fight for the Confederacy with Throckmorton leading his own company of mounted riflemen.

Politics

Like most suburban Texas counties, Collin County has consistently supported Republican candidates in presidential and congressional elections since the 1960s. The last Democrat to win the county was native Texan Lyndon Johnson in 1964. By the 2020s, Collin County had become considered competitive in national elections due to demographic and voting trends, though it remains Republican-leaning. In down-ballot races, Republicans hold all of the county-level offices and all but one of the county's seats in the state legislature. Despite its Republican lean, Collin County has trended leftward, as

Colleges and universities

Collin College opened its first campus on Highway 380 in McKinney in 1985. The college has grown to seven campuses/locations—two in McKinney and two in Plano and as well as Frisco, Allen, Rockwall, Wylie, Farmersville, and Celina. Collin College's official service area includes all of Collin County. Dallas Baptist University also has an extension site in Frisco, DBU Frisco, as well as the University of North Texas's extension side, UNT Frisco. The majority of the University of Texas at Dallas campus in Richardson, Texas lies within Collin County. While the main campus' address is officially within the jurisdiction of Richardson and Collin county, approximately one-third of the college is physically located within the border of Dallas county.


Transportation

With the Red Line operated by Dallas Area Rapid Transit (DART) ending with its northern terminus at Parker Road Station in Plano, most of Collin County is not served by any public transit agencies as of 2023. The Texoma Area Paratransit System (TAPS) transit service provided bus routes for a short period from 2013 until Collin County bus service was suspended in 2015. The North Central Texas Council of Governments (NCTCOG) in a 2022 meeting discussed the possibility of expansion of the Red Line corridor from Plano through Allen to McKinney. Either the Red Line or Silver Line could be extended north. While the Red Line could be expanded further north into Allen, Allen is currently unable to levy the 1% sales tax required to become a DART member city.
