Cities that had at least one printing press by the year 1500 showed a greater tendency to embrace Protestantism compared to those that did not have any printing facilities. This suggests that the availability of printed materials played a role in the religious shifts of the time. However, the influence was even more pronounced in cities with multiple competing printers, where the spread of ideas and information was more robust and dynamic.
This highlights the importance of access to diverse and competing sources of information in fostering significant social and religious transformations. The proliferation of printers likely allowed for a wider discourse and debate, facilitating the adoption of new ideologies such as Protestantism during a period of profound change in Europe.
