In May 1834, the “Hymn to the Constitutional Charter” was established as the anthem of the Kingdom of Portugal, and it was the official anthem until the establishment of the Portugese Republic, replacing the monarchy, in 1910. It was written in 1822 by Crown Prince Pedro of Bragança (later Emperor Pedro I of Brazil) to celebrate the Portuguese Constitution imposed by the liberals in Portugal. It is believed that he wrote both the lyrics and music of the hymn, since he was considered a very skilled musician; he titled this work in 1822 as “Imperial and Constitution Hymn”, and when he became King of Portugal in 1826 it was known as “Hymn to the Charter” and already very popular.
