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.

No Cortes assembled in reigns of John V (1706–1750), Joseph I (1750–1777), Maria I (1777–1816), John VI (1816–1826), with the exception of the 1820 assembly of the "Cortes Gerais e Extraordinárias da Nação Portuguesa" to draft a new constitution. The other exception was during the reign of Miguel of Portugal (1828–34), when the constitution was suspended and an old-style Cortes was assembled by Miguel in Lisbon in 1828 to recognize Miguel as the sole legitimate heir to John VI.
