Russo-Swedish War (Principia Moderni)

The Russo-Swedish War was a massive conflict that engulfed the world and began in 1669. It started as a conflict between Sweden and Russia due to Swedish desires for Russian territory and anxiety over the recent expansion of Russia. However, soon both sides began to grow larger due to a net of Alliances, resulting in a Global War. This was was perhaps the largest war in the history of the world.
