The First Universities
In the growing cities of medieval Europe, scholars organized into self-governing guilds of teachers and students — the first universities, at Bologna, Paris, and Oxford. Fed by classical and Arabic knowledge flowing in through Spain and the Crusades, they created something genuinely new: a permanent institution devoted to preserving, debating, and producing knowledge, independent of any single king or bishop. Nearly every university on Earth today, and the degrees it grants, descends directly from these medieval guilds.
A new way to record or transmit information lowers the cost of copying ideas and reorders who holds knowledge and power.
