Civilization V: The Swedish Saga, part 4 (1868 A.D. to 1951 A.D.)
1943 A.D.: Russia finally joins the other NAPA nations in denouncing Greece, abandoning its once-ally.
1945 A.D.: Greece declares war on the Principality of Salzburg, last bastion of the Danish royal government.
1947 A.D.: Just when it seemed there would be peace in the East, Rome unexpectedly declares new war on Russia. This breach of the NAPA treaties leaves many calling for its expulsion, but Rome assures the world that its strike was preemptive and necessary. The NDU, as the standing head of the Defense Council, recognizes that its own pending actions would be seen as hypocritical if it did not support Rome's tactics. It votes to expel Russia instead. The Celts back this decision, and Russia is removed from NAPA protection.
Later in the year, Danish Salzburg falls to the Greeks, erasing all traces of the royal government. The NDU begins moving units into position for the initiation of Operation Firestorm.
