After some internal dissensions in 1870–1871, ending with the removal of Ramón Cabrera as the head of the Carlist party, the Carlists started a general uprising against Amadeo I's government and its Liberal supporters. The Third Carlist War became the final act of a long fight between Spanish progressives (centralists) and traditionalists which started after the Spanish Peninsular War (1808-1814) and the promulgation of the constitution of Cadiz in 1812 which ended the "ancien regime" in Spain. Mistrust and rivalry among members of the royal family also enlarged the conflict. The three Carlist wars were started for diverse reasons: the establishment of the "Pragmatic Sanction" of Ferdinand VII caused the First Carlist War, the inability to find a compromise led to the Second Carlist War, and the proclamation of a foreign king as Spanish monarch sparked the Third Carlist War.
