The Invention of The Printing Press
Typically, Johannes Gutenberg is credited with inventing the printing press. However, that idea has been disputed, with suggestions that presses existed many hundreds of years before. However, there’s no dispute over the fact that Gutenberg popularized the machines and helped to spread an abundance of cheaply-produced literature across Europe.
The sudden availability of histories, religious books, and ancient texts helped to raise the literacy levels of the local population and allowed great thinkers of the age to stand on the shoulders of giants as they conducted their own work. No longer having to transcribe every single text by hand, information could be printed up and distributed with relative ease.
This wasn’t just true of books. Political pamphlets and manifestos were suddenly a viable tool for the mass evangelizing of peoples. Thanks to Gutenberg, the explosion of ideas in 15th Century and beyond was made possible. It’s an invention we still benefit from today.
