Which quick wars were there with a notable historical impact? I can think of the Austro-Prussian War of 1866 and the Franco-Prussian War of 1870-1871, but which other wars would qualify for this? One could think of the Western Front campaign in WWII in 1940, but that was just one campaign in a much larger and longer war.
I want to focus on countries that were roughly peer competitors to one another rather than grossly mismatched, such as with the 1983 US invasion of Grenada or the 1990-1991 Gulf War, where the power mismatch between the warring sides was extraordinarily uneven.
