Okay we all know that the creation of Spain as we know it happend due too events that played out causing a united Castile,a nd then Spain...
However, what if Castile had never gotten Sancho II as a ruler?
1036: Sancho II dies from choking, after the umbilical cord gets tied around its his neck, killing him.
1037: Ferdinand, father of what would have been sancho II, takes the thrown as King of Leon, Galicia, and Castile.
1065: Ferdinand dies, giving his son Alfonso VI the Kingdoms of Leon and Castile, while Garcia becomes the king od Galicia.
1067: At Garcia's party, he trips and hits his head hard. It causes brain damadge, and bleeding in the brain. he dies some days later.
1068: Having no sons or daughters, the thrown of Galicia is given to Alfonso IV of Leon and Castile.
1070: The three kingdoms are joined together as a permanent nation, the Crown of Leon.
Is this viable?
