How would Philip I of Castile divide his empire?

Ferdinand was more flexible that Charles. Make sure Charles gets placed in spain as a child instead of burgundy and marry him of to Isabella of portugal in 1520
Yeah that makes sense, Charles can be regent in Castile and then later co monarch with his mother and only focus on Spain and her empire then. Also would the Dutch revolt happen here as it did otl if they were under imperial and not Spanish control?
 
For the Spanish House of Habsburg how does this sound:

Carlos I of Spain (b. 1500: d. 1556) m Isabella of Portugal (b. 1503: d. 1560)

Issue:

Maria Anna of Spain (b. 1521)

Juan, Prince of Asturias (b. 1523)

Isabella of Spain (b. 1526)

Ferdinand, Prince of Spain (b. 1530)

Carlos, Prince of Spain (b. 1533)

How does that sound?
 
I think the daughter should be named Isabella, not Maria Anna. Double names weren't in fashion for at least 100 years later. Second daughter should be names Juana instead. Also there is infante of spain, not prince if I can be picky ;-)

Giving Napels to a bastard is different from giving it to another ruler when it will be in that persons domains. The newly formed Spain will want to consolidate their territories not give them away.

Alright, so how's this sound?

Carlos I of Spain (b. 1500: d. 1556) m Isabella of Portugal (b. 1503: d. 1560)

Issue:

Isabella, Infanta of Spain (b. 1521)

Juan, Prince of Asturias (b. 1523)

Juana, Infanta of Spain (b. 1526)

Carlos, Infante of Spain (b. 1530)

Ferdinand, Infante of Spain (b. 1534)

I imagine Ferdinand likely enters the church.

Doesn't make sense.IOTL,the King of Aragon willed Naples to his bastard son and made it fully independent.
 
I like that better and one or two stillborn/died in infancy for additional measures. Perhaps Ferdinand can serve as his brother's war aid as well, he can enter the church later and Juan will of course spearhead the counterreformation

Hmm, I do imagine that Isabella would be married off to Ferdinand's eldest son, Juan might be married off to a Portuguese Infanta as well, or perhaps an English Princess if there is one available.
 
As for Isabella, to me it does make sense that Carlos would do as he did otl, and have his eldest daughter marry Ferdinand's oldest son. The other kids could marry elsewhere.
 
Yeah Ludovico makes sense to me.

As for Ferdinand's kids, I think keeping them the same as otl makes sense.

Though a surviving Philip I of Castile might mean that Ferdinand names his eldest son after his father...
 
Alright.

How's this sound for Ferdinand and Anne

Ferdinand I, Holy Roman Emperor, King of Bohemia and Hungary, (b. 1503: d. 1561) m Anne of Bohemia and Hungary (b. 1503: d. 1560)

Issue:

Maximilian, King of the Romans (b. 1521) m Isabella of Spain (b. 1521)

Elisabeth, Queen of Poland (b. 1523)

Ferdinand, Archduke of Austria (b. 1526)

Anna, Archduchess of Austria (b. 1529)

Charles, Archduke of Austria (b. 1532)

Maria, Archduchess of Austria (b. 1535)

Ernest, Archduke of Austria (b. 1538)
