Editing Washtenaw County, Michigan (section)

===Early colonization===
The earliest histories mention French trappers and traders conducting trade in the area at the Potawatomi Trail and Pontiac Trail crossings of the Huron River, and later English then American settlers. The first successful settlement was established at the present site of [[Ypsilanti, Michigan|Ypsilanti]] about 1809 by French traders.{{sfn|Chapman|1881|pp=116–124}}

In 1822, the [[Legislative Council of Michigan Territory]] government defined the name and boundaries of the county, but attached it to [[Wayne County, Michigan|Wayne County]] for revenue, taxation and judicial affairs. Four years after the first platting out of the county, Washtenaw was established as a separate self-administered county by an act of the Michigan Territorial Legislature, in 1826.{{sfn|Chapman|1881|pp=116–124}} It was attached for administrative purposes to Wayne County until (before 1829) when county government was seated. [[Ingham County, Michigan|Ingham]] and other counties were formed from portions of territorial Washtenaw County.

Swamps were drained to lower the water table. The swamp northwest of the I-94 and US-23 intersection, and areas within Waterloo Recreation Area still appear as they did to early settlers. As productive farms became established, the local deer herds grew. In the 1820s and 1830s, the events surrounding the independence of [[Greece]] from [[Turkey]] inspired construction of Greek Revival buildings, and the names of townships, towns, and children.

The "frostbitten convention" was held at Ann Arbor, the county seat, in 1835. Statehood was delayed because Michigan claimed the [[Toledo, Ohio|Toledo Strip]], which was also claimed by [[Ohio]]. Following resolution of the [[Toledo War]] (1835–1836), in which Michigan Territory ceded its claim to Toledo in exchange for most of the Upper Peninsula (from the [[Porcupine Mountains]] eastward), Ohio withdrew its objection and Michigan became a state on January 26, 1837.

The convention also decided to move the capital from Detroit to a point further away from the Canadian border. After considering many existing communities, the delegates decided to build an entirely new capital city, which became [[Lansing, Michigan|Lansing]]. The [[University of Michigan]], founded at Detroit in 1817, was moved to [[Ann Arbor]] in 1839 as a consolation for the city not being named the new state capital, as it had sought. The university subsequently became and remains Washtenaw County's largest employer.

In 1849, the Michigan State Normal School (now [[Eastern Michigan University]]) was established in Washtenaw's oldest settlement, [[Ypsilanti, Michigan|Ypsilanti]]. It was elevated to collegiate status c. 1891 as Michigan State Normal College. The name was changed in 1956 to Eastern Michigan College, which was elevated to university status in 1959.
