Why did the English not want Mary to marry Philip II?

The English opposed Mary I's marriage to Philip II of Spain due to fears of losing political independence and the potential for Spain to exert control over England. Many viewed Philip as a foreign power, and there were concerns that his rule would lead to the persecution of Protestants and the re-establishment of Catholic dominance. Additionally, the prospect of a dynastic union raised anxieties about England being drawn into Spain's conflicts and ambitions in Europe. Overall, the marriage was seen as a threat to English sovereignty and national identity.
