Answer:
Dissatisfaction from the Spanish rule and treatment
Explanation:
Latin America, in general, was under the rule of the Spanish crown. The Spanish didn't really do anything in particular to develop their colonies, but instead they started to stagnate, while the majority of the people were living in bad conditions, and they were also treated very badly by the Spanish authorities. This started to revolt the people, so once they had proper leaders, and Spain was not in the best situation to be able to resist their revolutions, they revolted. The revolutions were successful, and one by one the Latin American colonies gained independence, ruining the Spanish empire in meantime.
