Final answer:
The causes of the events are: Pope Clement VII's fear of weakening the Catholic Church, Martin Luther's disagreement with the sale of indulgences, Charles V's desire to suppress Protestantism, and Elizabeth I's attempt to achieve religious stability in England.
Step-by-step explanation:
Causes of Events:
- Pope Clement VII refusing to annul Henry VIII's marriage to his first wife was caused by the fear of weakening the authority of the Catholic Church and the political influence of Catherine's nephew, Charles V of Spain.
- Martin Luther writing his Ninety-Five Theses was caused by his disagreement with the sale of indulgences by the Catholic Church and his belief in the authority of scripture and salvation through faith alone.
- Holy Roman emperor Charles V declaring war on Protestants in Germany was caused by his desire to suppress the spread of Protestantism and maintain Catholic dominance in the region.
- Elizabeth I becoming the queen of England as a tolerant Protestant was caused by the religious conflicts during her predecessors' reigns and her desire to achieve religious stability and balance in England.
