Final answer:
The spread of Luther's ideas was aided by the printing press and a desire for reform among those dissatisfied with the Catholic Church.
Step-by-step explanation:
Several factors contributed to the spread of Martin Luther's ideas during the Protestant Reformation.
One important factor was the invention of the printing press by Johannes Gutenberg. This made it possible to produce books and pamphlets much more quickly and in larger quantities, allowing Luther's writings and ideas to be disseminated more widely.
Additionally, Luther's ideas resonated with many people who were dissatisfied with the practices and corruption of the Catholic Church, such as the sale of indulgences. These individuals were eager for an alternative, and Luther's message of personal faith and direct connection to God struck a chord.
