Why did Henry vii get his children to marry from other royal families?

Henry VII arranged marriages for his children with other royal families to strengthen political alliances and enhance his dynasty's legitimacy. By connecting with powerful European families, he aimed to secure peace and stability for England, as well as to improve his family's status and influence. These strategic marriages helped to consolidate power and ensure that his heirs would have strong claims to thrones across Europe. Ultimately, this approach was part of his broader strategy to establish the Tudor dynasty and maintain its hold on the English crown.
