The Fourth of July is referenced or celebrated by characters in numerous Harry Turtledove works with a point of divergence after 1776. It is rarely relevant to the plot or helpful in defining the nature of any particular timeline.
Fourth of July in The Valley-Westside WarEdit
More than a century after the atomic war of 1967, people of The Valley - one of countless tiny nation-states arising from the former United States - still celebrated the Fourth of July with fireworks. Liz Mendoza noticed that Dan of the Valley referred to himself as an American, rather than a Valley man, when he talked of heated topics such as the Fourth of July or the Russians.
