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.
Ferdinand II of Portugal
In keeping with Portuguese law, only after the birth of his son in 1837 did he acquire the title of king. Ferdinand's reign came to an end with the death of his wife in 1853, but he served as regent for his son and successor, King Pedro V, until 1855. He and Maria founded the House of Braganza-Saxe-Coburg and Gotha, which would rule Portugal until 1910.
