The Alternate History Hub

The purpose of this thread is to merge all of the various differences that cause everyone's nations to exist and attempt to form them into some sort of semi-coherent history. List the world-affecting changes that brought your country into being (along with a general timeframe) and we'll try to make everyone's mesh with each other.

Should be anything close to global-scale in my history.

1315 - Refusing the request of the Pope to denounce the heresy that has established itself in the Kingdom of Irland and the Isles, Alexander I is excommunicated. Alexander I replies that the Pope has no hold over true believers in the Trinity, and in conjunction with several prominent clergymen who hold little loyalty to the Pope, sets himself up as the chief religious authority in the kingdom. He declares that the Insular faith is the one true faith, but assures religious minorities in the realm that tolerance is a great virtue in the eyes of the Trinity and that no man should be persecuted for his faith.

1316 - The Pope excommunicates all those who consider themselves to be of the Insular faith, denouncing them as heretics. For a time it seems that religious war may break out, but none does.

1796 - King Magnus VI issues a declaration claiming much of North America to be his by Divine Right and Right of Discovery. His full title becomes His Royal Majesty Magnus VI Magnusson, by Grace of the Allfather King of Irland and the Isles, Jarl of Dyflin and of Søreyar and of Grønland and of Island and of Orkney and of Mann and of Føroyar and of Hetland, Lord of Vinland and of Bjørnland and of Fjelland and of Gressland and of Karland, Defender of the Faith and Protector of the Realm.

1066: The Normans successfully invade England, but are driven out by the Scandinavians and return to Frankish vassalage.

1569: The first Parliamentary Monarchy is established.

1657: Scandinavian Catholics tolerate and accept the Insular faith followed by The Danelaw and the Kingdom of Irland.

Delta, you need to put dates in the OP.
