What were major events that led to the renaissance?

The Renaissance was catalyzed by several key events, including the fall of Constantinople in 1453, which prompted the migration of Greek scholars to Italy, bringing with them classical texts and knowledge. The invention of the printing press by Johannes Gutenberg around 1440 facilitated the spread of ideas and literacy across Europe. Additionally, the rise of Humanism emphasized the value of individual experience and classical learning, encouraging a cultural shift away from the medieval focus on religion. Economic growth in Italian city-states also fostered patronage of the arts and sciences, further igniting the Renaissance spirit.
