Answer:
The Spanish colonization of the Americas began under the Crown of Castile and spearheaded by the Spanish conquistadors. The Americas were invaded and incorporated into the Spanish Empire, with the exception of Brazil, British America, and some small regions in South America and the Caribbean. The crown created civil and religious structures to administer this vast territory. The main motivations for colonial expansion were profit through resource extraction[1] and the spread of Catholicism through indigenous conversions.
Taxation without representation simply means that people are being taxed without being allowed to have an elected official present in the body that makes the tax laws (in this case that body would be Parliament)--meaning that the people being taxed have no say in what types of taxes are fair or not. The colonists viewed this as tyrannical and morally wrong.
