Why did Martin Luther's ideas spread quickly throughout Europe?

Answer 1

Martin Luther's ideas spread quickly throughout Europe due to the invention of the printing press, which allowed for the mass production and distribution of his writings. Additionally, his criticisms of the Catholic Church resonated with many people who were dissatisfied with the church's practices and corruption. Luther's ideas also appealed to rulers who saw an opportunity to challenge the authority of the church and gain more control over their territories.
