Q: Passage: The 5 October 1910 revolution was the overthrow of the centuries-old Portuguese Monarchy and its replacement by the Portuguese Republic. It was the result of a coup d'etat organized by the Portuguese Republican Party. By 1910, the Kingdom of Portugal was in deep crisis: British pressure on Portugal's colonies, the royal family's expenses, the assassination of the King and his heir in 1908, changing religious and social views, instability of the two political parties , the dictatorship of Joao Franco, and the regime's apparent inability to adapt to modern times all led to widespread resentment against the Monarchy. The proponents of the republic, particularly the Republican Party, found ways to take advantage of the situation. The Republican Party presented itself as the only one that had a programme that was capable of returning to the country its lost status and place Portugal on the way of progress. After a reluctance of the military to combat the nearly two thousand soldiers and sailors that rebelled between 3 and 4 October 1910, the Republic was proclaimed at 9 o'clock of the next day from the balcony of the Pacos do Concelho in Lisbon. After the revolution, a provisional government led by Teofilo Braga directed the fate of the country until the approval of the Constitution in 1911 that marked the beginning of the First Republic. Among other things, with the establishment of the republic, national symbols were changed: the national anthem and the flag. The revolution produced some civil and religious liberties, although there was no advance in women's rights and in workers rights, unlike what happened in other European countries.
