Protestantism in mainland Europe began with the publication of the <em>Ninety-Five Theses</em> by Martin Luther in 1517. Martin Luther was a Catholic priest who disagreed with many of the teachings of the Church, such as the sale of indulgences. He complained about such practices in his Ninety-Five Theses.
Many people were inspired by his work, and his followers became known as Protestants, as they were protesting the shortcomings of the Catholic Church. However, such protests and conversions were controversial, and they were the target of much hate. This led to violence in many different areas, such as the Holy Roman Empire, Luther's home.
