In the European Middle Ages, advancements in science and technology, including engineering and aesthetics, were closely tied to the progress of ecclesiastical ideas and design. These technical developments significantly altered the contemporary world and have continued to influence Europe’s cultural and social evolution, including societal perspectives on people with disabilities. Our research investigates the practical implications of these technological advancements and their impact on a society deeply influenced by religion. We specifically focus on how these developments affected the most vulnerable individuals and the longstanding societal bases for the exclusion of people with disabilities. This research primarily utilizes content analysis to uncover insights that clarify the historical role of disability within European societal evolution. Our work aims to foster a correct understanding that transcends the limitations of political decisions, integration laws, and societal expectations, which alone are insufficient to alter deeply ingrained inclinations. Additionally, our research contributes to the fields of technology history and disability history, connecting these areas to offer a new perspective on past and present challenges. This interdisciplinary approach not only addresses historical impacts but also aids in overcoming outdated attitudes towards disability and promotes the strengthening of new competencies for societal integration. Overall, by exploring the intersections of technology, history, and social development, our research provides valuable insights into the complex relationship between societal progress and the inclusion of people with disabilities, aiming to influence both academic fields and practical policy considerations.
