ABSTRACT Failed university is a notable phenomenon in the history of universities in the Middle Ages: some university foundations were not completed at all, some other universities disappeared in the medieval times. Moreover, many medieval universities once had unsuccessful experience. The failures and the successes both together form a complete history of medieval universities. A study on the failed universities will provide a new perspective to rethink and to verify the essential elements for a successful university foundation. So, this research focuses on the failed universities in the 14th and 15th centuries. Several typical failed cases in different territories (e.g., Barcelona, Pforzheim, Lucca) are selected and compared with successful university foundations. Through detailed analysis of the process of the university foundations, this research is to explore the motives of various university founders and demonstrate the necessary preconditions of founding a university in the Late Middle Ages.

中世纪失败大学的分析

摘要失败的大学是中世纪大学历史上的一个显着现象：有些大学的基础根本没有完成，有些其他的大学则在中世纪消失了。而且，许多中世纪大学曾经没有成功的经验。失败和成功都共同构成了中世纪大学的完整历史。对失败大学的研究将为重新思考和验证成功大学基础的基本要素提供新的视角。因此，这项研究的重点是14和15世纪失败的大学。选择了不同地区的几个典型失败案例（例如，巴塞罗那，普福尔茨海姆，卢卡），并将其与成功的大学基金会进行比较。通过对大学预科课程的详细分析，
