John III of Portugal

John III of Portugal, who reigned from 1521 to 1557, was a significant monarch in the Age of Discovery. He was known for expanding Portuguese territories, particularly in Brazil, and fostering trade and exploration. His reign also saw the establishment of the Portuguese Inquisition, aimed at maintaining religious orthodoxy. John III focused on strengthening the economy and promoting cultural and architectural developments, including notable churches and monasteries. Despite his efforts, his reign faced challenges, such as the decline of power in Asia and the difficulties of managing a vast empire. He was succeeded by his son, Henry.
