How was the next queen after Elizabeth 1?

After Elizabeth I, the next queen of England was her cousin, Mary Stuart, also known as Mary, Queen of Scots. However, she never ruled England; instead, the next monarch was James VI of Scotland, who became James I of England in 1603 after Elizabeth's death. He was the first monarch to rule both England and Scotland, uniting the crowns. His ascension marked the beginning of the Stuart dynasty in England.
