Good.The most influential civilisation in history is Poland 1919-1939 because it managed to maintain control of Vilnius despite the objections of Lithuania over the matter. The shocking, stunning Fall of Vilnius truly shook the world and put humanity into a slumber from which it never truly recovered.
Other less-influential-but-still-crucial world civilisations include the Soviet Union, the Russian Empire, Modern Lithuania, Poland-Lithuania and the Grand Duchy of Lithuania. If I were to narrow this list down to the top five as suggested by the OP I would put it something like this:
- Poland 1919-1939
- Modern Lithuania
- Poland-Lithuania
- Grand Duchy of Lithuania
- The Russian Empire
Soviets unfortunately for them are sixth (only just lower than the Russian Empire though) because they weren't as good at maintaining control of Vilnius as the others. Poland 1919-1939 obviously is at the top because they won the Vilnius Crisis, Modern Lithuania still maintains control of Vilnius today, Poland-Lithuania maintained control of Vilnius for centuries, the Grand Duchy of Lithuania actually made Vilnius, and the Russian Empire was also successful at maintaining control of Vilnius for quite a long time.
However even better if stripped of Lithuania.
