The war began with the raids on the Spanish fleet and colonies by English privateers like Francis Drake and John Hawkins. These raiders often had licenses issued directly from the English crown, and their actions caused economic losses and humiliation to Spain.
1. Religious disputes: England was a Protestant country under Queen Elizabeth I, while Spain was a staunchly Catholic nation under King Philip II. Religious tensions between the two nations had been growing for years, and the execution of Catholic Mary, Queen of Scots, by Elizabeth in 1587 further strained relations.
2. Economic rivalry: England was emerging as a major maritime power, challenging Spain's dominance in trade and exploration. English privateers, such as Francis Drake and John Hawkins, raided Spanish ships and colonies, leading to significant economic losses for Spain.
3. Territorial disputes: England and Spain had conflicting claims to various territories, including the Netherlands and the New World. The Spanish Armada was partially motivated by a desire to curb English influence and secure control over these disputed areas.
4. Support for rebellions: England supported Protestant rebellions against Catholic rule in the Netherlands and France, while Spain supported Catholic rebels against Elizabeth in Ireland. This mutual intervention in each other's internal affairs further intensified the conflict.
5. Spanish Armada: In response to England's actions and growing power, King Philip II of Spain decided to launch a massive invasion force known as the Spanish Armada in 1588. The Spanish Armada aimed to overthrow Queen Elizabeth I and restore Catholicism in England. However, the English fleet, led by Admiral Lord Howard of Effingham and Sir Francis Drake, defeated the Spanish Armada, marking a significant turning point in the war.
