I have some ideas for you.

World War II: The War opens massively early with the Spanish Civil War when Germany openly supports Fascist Spain and declares war on their enemies, thus prompting Britain and/or France to support Spain.

Another WWII idea: Japan decides not to bomb Pearl Harbor, leading America to not join the war until later, or not at all.

WWII: The Molotov-Ribbentrop Pact is not signed, so that the Soviet would stay out of World War II until Germany conquered Poland and then went after the USSR. Thusly the war would fare much worse and possibly longer due to delayed Soviet participation.

Prehistory: Woolly mammoths manage to survive by fleeing northwards, perhaps to Alaska of Siberia, or even nearer to the Pole.

Prehistory: The Indus River Civilization is attacked by a disease in its early stages.

Prehistory: The Agricultural Revolution does not happen as more wild beast begin to appear. so that more people hunt.
