Taxation without representation, the colonists were taxed by the British without the Colonists own government being consulted. Another reason was the that the British did not allow the Colonists to move into the newly aquired area of the northwest region(Ohio, Kentucky etc.), because the British promised the area to the Native Americans. And may I note the Colonists actually considered themselves to be British.
Churchill meant that the Soviet Union had separated the eastern European countries from the west so that no one knew what was going on behind the “curtain.” He used the word “iron” to signify that it was impenetrable.
Los derechos territoriales españoles sobre Alaska y la costa oeste de América del Norte databan de la bula papal de 1493 y del Tratado de Tordesillas, que asignaron a España todo el territorio de América tras su descubrimiento en 1492. En 1513, los derechos españoles se reforzaron cuando el explorador español Vasco Núñez de Balboa cruzó el istmo de Panamá y descubrió el océano Pacífico, tomando posesión de todas las tierras bañadas por ese océano para la Corona de España. Sin embargo, la colonización española del territorio al norte de México no comenzó hasta el siglo XVIII, cuando se fundaron misiones y asentamientos en la costa norte de Las Californias (California).
Colonialism is the establishment, exploitation, maintenance, acquisition and expansion of colonies in one territory by people from another teritory. It is a set of unequal relationships between the colonial power and the colony and between the colonists and the indigenous population.
