The popularity of printing presses around the world means a wider spread of ideas, threatening the power structure of the whole of Europe. In 1501, Pope Alexander VI promised that anyone who prints manuscripts without the approval of the church will be expelled from court. Twenty years later, the books John Calvin and Martin Luther spread, turning Alexander's fear into reality. This threat is exacerbated, and Copernicus’s revolution in his celestial sphere is regarded by the church as a heresy. By 1605, the first official newspaper, the relationship was printed and distributed in Strasbourg. Newspapers have appeared throughout Europe, formalizing the printing industry's contribution to literacy, education and widespread access to unified information for the general public.
