- There is some good food for thought at Vanport, Oregon
- Native American peoples of Oregon
- History of Oregon#Racial discrimination
- Racism in the United States
- Segregation in Seattle (a stub)
- Hells Canyon Massacre (an article begging to be expanded).
- I would also look through Category:Racism and Category:Racism in the United States and Category:History of racial segregation in the United States and especially Category:History of racism in the United States to see if there are similar articles and to see how they are organized.
- Based on an initial look through those articles and categories, it seems like the practice has been to build articles related to a topic like "Racism in [state or country]" and then create a category like "History of racism in [state or country]" for those articles to live in, rather than building a "Racism in X" article.
- this article about Japanese immigrants in Oregon. There is probably more good stuff on race relations, and references to sources, at the Oregon Encyclopedia. This article on Japantown in Portland, for example, is right up your alley!
- this article, in which someone describes "Portland's African-American culture -- a black culture distinct from ones found in the Bay Area and Chicago".
- African Americans in Oregon, or even African Americans in Portland, Oregon.
Chinese Americans especially in the building of the railroads.
- The Racist History of Portland, the Whitest City in America
- Oregon Encyclopedia on Black Exclusion Laws
- We should make at least a stub on Oregon ballot measure 14 (2002) which finally removed racist language from the constitution
