History of Portugal (1834–1910)
Militant Republicans and their allies in the Carbonária were not willing to remain in the shadows of the constitutional monarchy. Between 4–5 October 1910, members of the Carbonária, republican youth, and elements of the army instigated a coup d'état against the already weak constitutional monarchy. The young king and his family, after a few miscues, escaped from the Palace in Mafra to exile in England. On the morning of 5 October 1910, the Republic was declared from the balcony of Lisbon City Hall, ending eight centuries of monarchy in Portugal.
History of Portugal (1834–1910)
Manuel II would reign for only a short time, as republican forces continued to attack the monarchy and its institutions, even though the young king was considered a popular monarch. His unexpected accession to the throne (18 years of age), was marked by the brutal murder of his father and brother, yet his reign was pragmatic and respected the principles of the constitutional monarchy. Despite threats from the ultra-militant members of the Republican Party and the Carbonária, King Manuel courageously took responsibility for upholding the institutions of the State and the rule of law.
