Located in Oregon's mid-Willamette Valley, French Prairie is bounded by the Willamette River to the north and west, the Pudding River to the east, and the remnants of Lake Labish (Lac labiche) to the south. In the 1800s, the five major towns of French Prairie were Butteville, Champoeg, St. Paul, St. Louis, and Gervais. Frenchman Pierre Charles Fournier de Saint Amant, who visited Oregon in the early 1850s, was one of the first to use a version of the term "French Prairie" in print, referring to the area as les prairies françaises.

French Prairie takes its name from the bi-cultural French Canadian and Indian families who re-settled the area in the 1830s. These French-Indian settlers were important historical actors in Euro-American colonization of the region, which began with the fur trade in the 1810s. French Prairie was originally the home of the Ahantchuyuk Kalapuyans, an aboriginal people whose numbers declined precipitously during 1830s and 1840s as a result of disease and Euro-American emigration.

During the early 1840s, the French Canadian men who settled in French Prairie attended debates about the organization of a community government. Wary of the bureaucratic and taxation burdens imposed by a more complex governmental apparatus, they largely supported a limited governmental structure. Nevertheless, in May 1843 at Champoeg, a half dozen or so of the leading French Canadians joined with their American neighbors in voting to form a provisional government. Eventually, the French Canadians who did not vote for the new government reached a compromise with their American neighbors due to their long-standing influence in the valley and their position as landholders.

Champoeg was largely washed away in the flood of 1861, and a year later the original townsite from the mid-1800s was officially abandoned. Following the devastating flood, the town of St. Paul became the major focus of settlement in the northern section of French Prairie. From the late 1800s through the 1910s, the author's great-great-grandparents, Adolphe and Marguerite Jette, ran several related businesses at the relocated Champoeg (Newellsville).

At the turn of the twentieth century, a statewide heritage movement developed to commemorate the history of the Oregon Provisional Government. The Oregon Historical Society and the Oregon Pioneer Association, which included many descendants of the French-Indian settlers of French Prairie, supported this effort. In May 1901, the State of Oregon unveiled a historical marker at Champoeg to commemorate the May 1843 vote. From 1901 through 1958, the state progressively secured title to 159 acres encompassing the original townsite at Champoeg and developed the area into the Champoeg State Park. Through the mid-1900s, Champoeg Day, commemorating the history of the Oregon Provisional Government at Champoeg, was a popular local event.

Today the Champoeg State Heritage Area, considered a "gateway" to the Willamette Valley, hosts a visitor center, historic sites, campsites for travelers, and bicycle trails. The area sponsors outdoor and nature activities and educational and historical programs for visitors and students. Although the history of French Prairie is now less prominent in the state's collective memory, the staff and volunteers at Champoeg Park and the Friends of Historic Champoeg educate visitors and students about the area's history, including the role of the French-Indian settlers in the early 1800s.
