Explanation:
Colonization, or colonisation refers to large-scale population movements where the migrants maintain strong links with their or their ancestors' former country, gaining significant privileges over other inhabitants of the territory by such links. When colonization takes place under the protection of colonial structures, it may be termed settler colonialism. This often involves the settlers dispossessing indigenous inhabitants, or instituting legal and other structures which systematically disadvantage them.
In its basic sense, colonization can be defined as the process of establishing foreign control over target territories or people for the purpose of cultivation, often through establishing colonies and possibly by settling them.
In colonies established by Western European countries in the Americas, Australia and New Zealand, settlers (supplemented by Central European, Eastern European, Asian and African people) eventually formed a large majority of the population after killing, assimilating or driving away indigenous peoples.
The declaration was a laundry list of affronts to the colonies by King George III, wherein Jefferson et.al. argued that since the monarchy did not treat the colonists like other Britons, the colonists had the right to form their own sovereign nation. It was also intended to justify this action to other monarchies to prevent them from helping Britain retain the colonies under the doctrine of Intervention. So it helped to justify the war domestically and internationally.
Democracy is an elective system that the people are the government.
African American citizens took advantage of their newly granted rights by using them wisely.
for example: voting rights
they voted for the parties that supported giving African Americans equality
