The Braganza Dynasty was a royal family that ruled Portugal from 1640 until the establishment of the Portuguese Republic in 1910. It emerged after a successful revolt against Spanish rule, leading to the restoration of Portuguese independence. The dynasty is known for its significant contributions to Portuguese culture, exploration, and colonial expansion during the Age of Discovery. The Braganza family also played a crucial role in the history of Brazil, as they became the ruling house of the Brazilian Empire when Dom Pedro I, a member of the dynasty, declared Brazil's independence in 1822. The dynasty's influence extended beyond Portugal, shaping the political landscape of both Portugal and Brazil for over two centuries.
