King John V of Portugal reigned from 1707 to 1750 and is known for his efforts to strengthen the Portuguese monarchy. He was a patron of the arts and architecture, commissioning many grand buildings, including the Mafra National Palace. His reign marked a period of prosperity for Portugal, largely due to the wealth generated from its colonies. John V was also notable for his diplomatic relations, particularly with Pope Benedict XIII, which helped to enhance the influence of the Portuguese crown. Despite his achievements, his later years were marked by financial difficulties, leading to a decline in royal power after his death.
