*Do not lose any city until 1900AD
Note that the Mughals were named "Mamluk sultanate" at their beggining according to wikipedia.
Sweden:
Not a viking rebirth after all, I changed my mind. It should be a completely independent civ (so Vikings will become Denmark-Norway at Swedish spawn, not at catholicism convert).
Spawn in 1523 in Stockholm.
UU: swedish cavalry (amphibius invasion). (modeling the arms of Gustav adolph)
UB: Gothic castle: it doesn't become obselete

Proposed goals:
*Swedish empire (control: Sweden, Finland, Warsaw, Saint-Peterbourg, Hambourg, a city in North America, a city in west Africa) by 1721.
*Complete the Nobel Prizes Project by 1895.
*Be the first to adopt the combination Republic, Universal Suffrage, Egalitarianism, Environmentalism, Secularism and (the last military civic) by 1940AD.
It starts with Printing Press. It spawns protestant or catholic if Protestantism isn't founded. Then Swedish will found it.
The
Nobel Prizes:
It will be a world project (similar to the Manhatan Project) that requires Scientific method and Chemistry. Effects: +1

per specialist worldwide. I had proposed it as world wonder, but it isn't a building afterall.
