Who is the oldest publishing house?

The title of the oldest publishing house goes to Cambridge University Press, which was founded in 1534 by King Henry VIII. It began during a period of immense upheaval in the publishing industry, as the Protestant Reformation was reshaping publishing and education with the support of the British monarchy and the rise of mechanical printing by German Johannes Gutenberg. Through the centuries, Cambridge University Press survived through different eras, including the English Civil War, the Industrial Revolution, and the World Wars. Today, it stands as one of the most esteemed academic publishers, with an extensive range of books, journals, and educational resources across various fields of study.
