So this is a challenge to make Edgar King of England after the following happens.
William the Bastard does not try to contest the succession of Edward the Confessor, despite being promised the throne. I know, I big huge shock. He spends his effort and money on something else, that you can make up your mind on.
Harold Godwinson still thinks William and the Normans will launch an imminent invasion and gathers his forces waiting for an attack that never comes. The Vikings still launch an attack on England. Earl Morcar is still defeated at Fullford. Harold still marches north and beat the Vikings in a surprise attack (maybe at Stanford bridge too? Pick you place), with a 3 to 1 casualty in his advantage and he still survives the battle.
But, William isn't coming.
The challenge is to not only make Edgar the King of England, but have Morcar, earl of Northumbria, Cadoc of Cornwall, some sources say Earl of Cornwall from 1060 and some say he was merely a manor Lord elevated to Earl by William the Conqueror, and Stigand, Archbishop of Canterbury support Edgar's crowning. All of them supported Harold Godwinson over Edgar and Harol seems like he would be a reasonable ruler (that is not drive his supporters away), so Harold is probably going to need to die at some point.
