Irish Reunification
As mentioned by Data in TNG’s third season episode “The High Ground,” the Republic of Ireland and Northern Ireland bring an end to a century of violence and British influence to become a united nation in its own right in 2024.
We’re probably closer to the chance of Scottish independence happening sometime soon rather than that in our own timeline, but according to Data, reunification wasn’t just a step on the path to a more globalized Earth in terms of a planetary society, the event was a notable example of terrorism as a successful political instrument.
