King João VI was the ruler of Portugal from 1816 until his death in 1826. He was born on October 13, 1767, and became king after the death of his mother, Queen Maria I. His reign was marked by significant events, including the transfer of the Portuguese court to Brazil in 1808 due to the Napoleonic Wars. During his time in Brazil, João VI established the country as a kingdom, which later contributed to Brazil's independence in 1822. After returning to Portugal, he faced political challenges and the rise of liberal movements. He died on May 10, 1826, leaving a complex legacy.
