Historically, Spain, after overthrowing the Bourbon Dynasty, established the Spanish Republic. However, the hastily established republic did not slow down Spain's decline; rather, the frequent changes in the republican regime led to even greater chaos within Spain, ultimately paving the way for the restoration of the monarchy.
Carlo's role is to propel the Portuguese into launching a revolution to overthrow the royal family and establish the Portuguese Republic.
The hastily established republic by the Portuguese is destined to be unable to effectively govern the country, and with Spain causing troubles on the side, Portugal's economy is bound to collapse even further.
At this time, the Portuguese people will also recall the merits of the monarchy. But since their own royal family has been overthrown, they can only restore the monarchy by either electing a king or nominating a noble.
