Why was renaissance a cultural revolution?

The Renaissance was a cultural revolution because it marked a profound transformation in art, literature, science, and philosophy, shifting focus from medieval religious themes to Humanism and individualism. This period saw the revival of classical learning from ancient Greece and Rome, leading to innovations in artistic techniques and a greater emphasis on observation and empirical evidence in science. The invention of the printing press facilitated the widespread dissemination of ideas, fostering a more educated public and challenging established authorities.
