Civilization V: The Swedish Saga, part 2 (430 A.D. to 1702 A.D.)

War brews in the Age of Discovery

1225 A.D.: The Danes and the Swedes enter into a research agreement.

I was waiting for this very turn for Denmark to have enough gold to make this work, and they beat me to the proposal. Essentially, we both pay a large sum of gold (which poofs into nothingness) and get a huge, mutual science bonus after several turns have passed. Since I'm currently pretty rich, I'm going to try to make as many of these agreements as I can.

1260 A.D.: A professor at the University of Sigtuna invents the compass. Swedish ships use the new device to travel the seas in ways never before possible. A Swedish Golden Age begins.

My economy was already booming. Now, the money coming in is INSANE. I start buying buildings that will increase my production capabilities in every city, and head straight for Astronomy, which will let me cross ocean tiles. In terms of the historical Norsemen, I'm already about 250 years behind in discovering the New World.

1290 A.D.: Greece seeks allies to put down the warmongering German zealots, whose crusaders continue to harass Austria. Sweden agrees, provided they are given time to prepare.

Amazingly, I made it 5300 years without ever being at war with a major power. Granted, calling Germany a "major power" at this point is fairly generous. They've made some impressive comebacks over the centuries, but against the superpower that is Greece, they have just shy of a prayer. Especially with how many troops they've lost trying to take Vienna.

1300 A.D.: The unofficial start of the Late Middle Ages and the Swedish Age of Discovery. Aided by compasses, Swedish longships will encounter the island city-states of Ragusa, Rio De Janeiro, Venice, Florence, Jerusalem, and Monaco before their Golden Age ends in 1325.

By this time, Awesomeness has also become the majority religion all across Sweden, and even among some of the Southern Stormlander lords living under Danish rule.

Summer, 1345 A.D.: The Continental Alliance of Sweden, Denmark, Greece, and Austria declare war on Germany. Only the Celts remain, as ever, neutral.

Shortly thereafter, students at the University of Sigtuna develop telescopes and pioneer Astronomy, launching Sweden into the Renaissance.
