There were, of course, many important events during Elizabeth's long range. Let us look at two of the most important of them.
First, there was the Act of Uniformity, which restored the Book of Common Prayer. This represented a reinstatement of the Protestant faith that her father had helped to institute in England. It made England into a solidly Protestant country.
Second, as a Protestant country, England came to be an enemy of Catholic Spain. This led to the most famous incident from Elizabeth's reign, which was the attempted invasion by Spain. This was the incident in which the British defeated the Spanish Armada.
