Ferdinand II
Philip I of Castile was Charles V's father.
No he was the nephew of Catherine of Aragon. Charles was the son of Catherine's sister Juana and her husband Phillip. Charles was known as Charles I in Spain.
Charles v king of Spain
Charles V was the nephew of Catherine of Aragon. He was the son of Joanna of Castile and Philip the Handsome, making him the cousin of Catherine, who was the daughter of Ferdinand II of Aragon and Isabella I of Castile. Their familial connection played a significant role in the political dynamics of the time, particularly during the events surrounding Henry VIII's desire to annul his marriage to Catherine.
Francios Edit: Francios? Catherine of Aragon's nephew was Charles V of Spain. At the time of Henry VIII's "divorce" Charles V, the Holy Roman Emperor had the Pope under House Arrest, hence why Henry VIII was refused an annulment of the Catherine/Henry marriage.
The treaty arranged for the marriage of Charles VI's daughter Catherine to Henry V of England
Queen Catherine's Nephew was Charles V/I, who was King of Spain, King of Naples, Lord of the Netherlands, and Holy Roman Emperor meaning that Charles V/I was the most power man in Europe and he loved his aunt very much.
It was definitely a contributing factor mainly as in 1527 Charles V (Catherine of Aragon's nephew) imprisoned the Pope and as the Pope was the only person able to grant an annulment it was prevented due to Charles V.
Philip II
Henry VIII of England wanted the Pope to annul his marriage to Catherine of Aragon. The Pope refused to do so, possibly because of pressure from Catherine's nephew, Charles V of the Holy Roman Empire.
