Step-by-step explanation:
After what organizational model were the first universities based? The first universities were based on a variety of institutional models, but among the most influential were those akin to the Academy founded by Plato in Athens, which was a significant center of thought for centuries. The Library of Alexandria and its associated Museon, funded by the Ptolemaic government, is often considered to be the first research university in the western world. Additionally, religious institutions like the monasteries that preserved learning after the fall of Rome played a role in the early development of universities. These monasteries not only safeguarded knowledge but eventually became sites of formal education in their own right, like the cathedral schools that evolved into the University of Paris. Universities like Oxford and Bologna followed, often training students for careers in civil service or the classic professions: medicine, law, or theology.
