When was the first movable-type printing press invented?

Around 1440, Johannes Gutenberg developed the movable-type printing press in Mainz, in what is now Germany. His system used reusable metal type and a press adapted from existing technologies, allowing books to be printed much faster than by hand. The Gutenberg Bible, produced in the 1450s, became one of the most famous early printed books. Printing helped spread literacy, science, and religious reform across Europe. It is often called one of the most important inventions in history.
