What I know about Washington State History

What I know about Washington. Well I dont know that much, I know it was settle a long time ago and I'm doing a research about it so by the time that I'm done with the research I will know exacly when it was settle and who settled it. And there is always something that represents the state for example California is represented by the brown bear so Washington is represented by Mount Rainier and a green flag of the president Washington. Washington was settle by indians and then the white people came and took over so now they own washington. And they did their own laws and they took the indians and african americans as slaves. Well that's what I think it happened and a guess too. But like I said I will know all that by the time I fished with this research and reading a book that I'm reading abouts Washington. So will tell you more about it when I finish my research and when I finish reading my book.
