I can't remember, so it can't be important

Hey, there are quite a few things missing from that timeline! Here’s a non-comprehensive addendum:

1899-1902 – The Philippine-American War

1910 – Jim Jeffries’ loss to Jack Johnson causes race riots

1916 – The Everett Massacre

1919 – The Omaha Race Riot

1919-1921 – The First Red Scare and the Palmer Raids

1920’s – Invasions of various Central American countries on behalf of American corporations

1929 – The Crash of '29 begins the Great Depression with a bang

1932 – Forced eviction of the Bonus Marchers

1931-1937 – The Scottsboro Boys' Trials

1937 – The Battle of the Overpass

1942 – Executive Order 9066 leads to internment of Japanese and Japanese-Americans

1947 – Congress overrides President Truman’s veto of the Taft-Hartley Act

1948 – Supreme Court upholds prayer in schools

I have no problem in taken pride in a job well done, but a little introspection helps keep one from getting smug and self-satisfied, especially when some of the accomplishments are dubious at best...
