Prior to World War I, the Medal of Honor was it. The Distinguished Service Cross and the Navy Cross were added in 1918. The Silver Star started out as a citation star on the campaign ribbon in WWI, but became a full medal in the 30’s. The Distinguished Flying Cross was established in the 20’s and the Bronze Star and Air Medal are World War II additions.

Thanks, I was hoping somebody would fill-in the facts on when the other awards were adopted.
