Modern hospital is a place to treat sick patients. However, it took quite a long time for hospitals to establish themselves as a medical institutions in France. In medieval period, hospitals were the entities which not only treated the patients but also accommodated passing pilgrims and provided the poor with the charity. Hospitals performed such a comprehensive function and the administration was taken by the clergy. But the 16th and the 17th centuries, people started to have complaint with hospitals because hospitals could not well respond to the poverty and illness due to the food crisis and the outbreak of epidemics. Accordingly in the second half of the 17th century, the royal government started to reform the hospitals. The royal government ordered hospitals to separately accommodate the poor and the patients and to make the poor work. However, these attempts failed to resolve the poverty but made people fearful of hospitals. Problematic was the fact that the clergy and administrators did not pay proper attention to the poor who was detained in hospital. In the 18th century, however, the doctors were able to raise their status in the backdrop of the gradual development of modern medicine and priests were gradually expelled from the hospital.
