So Charles V inherited a massive empire from each of his grandparents. In 1521 he gave the Habsburg Crownlands (the Archduchy of Austria) to his brother Ferdinand, which combined with Bohemia and Hungary would create the Habsburg Monarchy. What if, instead of abdicating these lands to Ferdinand, Charles instead merely appoints him as governor, especially sense Ferdinand would later inherit Bohemia and Hungary from his brother-in-law? How would this effect history? Would Charles merely give these lands to him later, when he abdicates in 1556 (assuming he still does this)? Would a massive Habsburg empire eventually overextend itself and collapse? Or would the empire find a way to survive and stay the dominate European power?
