Queen Elizabeth I reigned during the time of the Spanish Armada, which was launched in 1588. Elizabeth, who ruled from 1558 to 1603, was the last monarch of the Tudor dynasty and is remembered for her remarkable leadership during a turbulent period in English history. The conflict with Spain intensified due to religious and political tensions, as Elizabeth was a Protestant and sought to counter Spanish Catholic influence. The successful defense of England against the Armada was pivotal, establishing England as a formidable naval power and strengthening national pride. Elizabeth's reign is often referred to as the Elizabethan Era, known for cultural flourishing and exploration.
