So irl Charles V had a MASSIVE empire in both Europe and the Americas due to the bedroom diplomacy of his predeccessors. Before he died he decided to partition his empire between his brother and son. Basically all of the empire went to his son, Phillip, while Austria (and the HRE crown) Went to his brother, Ferdinand. Spain would go on to carelessy ruin its economy, lose to the Dutch, and the territorial cutting measures Charles took were rendered mute anyways when Portugal was added to Phillip's lands in 1580. So WI Charles had given more land to Ferdinand. I'll say he give all the lands in the HRE (The Netherlands, France Comte, and Milan) to Ferdinand while Spain, Naples, and the Americas remain with Phillips (and later Portugal). How does this affect colonization, the HRE (now like 1/3rd of it is directly in Habsburg rule), the 80 years war, and overall the long term survival of Habsburg rule.
Maybe they make it to today?
