PoD is vert easy-some unfortunate accident happens to Emperor Charles V, resulting in his premature death in summer 1527, ending personal union between Spain and Holy Roman Empire much earlier than IOTL.
So baby Felipe II is heir of Spain and Burgundy (with Isabella of Portugal as regent in Spain and Charles' aunt Margaret as regent in Burgundy I guess), while Ferdinand is getting Imperial throne much earlier than IOTL.
So HRE would not have absent emperor, as Ferdinand would have no reason to wander from Germany to Spain and back. How would he deal with reformation? Also, with earlier split there would be less coordination between Spanish and Imperial troops, which should be good for France? What are your thoughts?
