Lisbon Regicide
The assassination of King Carlos and the Prince Royal was the effective end of a constitutional monarchy in Portugal (later confirmed by the 5 October 1910 revolution). The regime functioned for another 33 months with growing agitation and demands for reform (although considerably less than in the future First Republic). It cannot be denied that the weak and permissive attitude in the Government of Acclamation was an incentive for the Republican Party to attempt another coup. The assassinations did not change the system of government; instead, they delayed the change.
Military Order of Saint James of the Sword
In 1910, when Portuguese monarchy ended, the Republic of Portugal abolished all the Orders except the Order of the Tower and Sword. However, in 1917, at the end of World War I, some of these Orders were re-established as mere Orders of Merit to reward outstanding services to the state, the office of Grand Master belonging to the Head of State - the President of the Republic. The Military Order of St. James, together with the other Portuguese Orders of Merit, had its statutes revised on several occasions, during the First Republic (1910–1926), then in 1962, and again in 1986.
