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.
Portuguese heraldry
This restriction would become irrelevant when King Manuel I forbade the use of arms to those who were not of the Portuguese nobility. This restriction against burgher arms in Portugal lasted until the end of the Monarchy in 1910, although, by that time, it was very common to a burgher who stood out in politics, commerce, industry, agriculture, military or other matters, to be ennobled and so to become entitled to bear a coat of arms.
