Sofroniou, A: Empires and Colonialism

An empire is the absolute dynasty of a group of countries under the rule of one sovereign State. It can be an extensive territory, an aggregate of many States, all under the ultimate authority of one person, an emperor or empress.
It may also be a ruling of people reluctant to give up carefully nurtured empires, which are governed by supreme and extensive political dominion, with absolute control and paramount influence. In years bygone, this was mainly the position or dignity of an emperor, now very rare.
In a few cases, throughout history, an empire-builder (a person who added to a territory) sought to increase his or her country's authority. A good example would be that of the British Empire who often employed a British overseas administrator, whose responsibility would be to sustain the governed areas and to handle the activities regarding the building of the worldwide empire.
According to scripted historical events, there were many empires in the world, where some are still taught in schools.
