Answer:
The absence of armed fight against the mother country (Spain and Portugal), and the result of each independence.
Step-by-step explanation:
The main characteristic of the independence movements of the Spanish colonies is that in almost all there was a war between the colonists and colonizers that dragged on for some years and ended with the victory of the colonists. It was like that in Chile, Uruguay, Argentina, and Bolivia. In Brazil, there were several conflicts during the Independence process, but none directly influenced the Declaration of Independence.
The main difference between the Independence movements of Brazil, Argentina, Uruguay, and Chile is the result achieved by each country. In Argentina, Chile, and Uruguay, declarations of Independence took these countries directly to the republican regime, while in Brazil there was only a political break with the metropolis maintaining the entire system that was in force during the colony.
