Crimean War - 1. Imperial Russia, 2. Ottoman Empire, 3. England (UK)

WW1 - 1. Serbia, 2. Austria, 3. Russia

First Balkan War - 1. Serbia, 2. Ottoman Empire, 3. Greece



* Ottoman Empire and United Kingdom fought as one, so even though it was a lot of countries of each involved, they should still count as one country. But if not, I'll take England as UK.
