Modern imperialism, forcing supremacy over weaker nations, had constructive effects in modern times which are as follows :
(a) Physical Reformation : For maintaining control over the colonies, the European nations brought about reformations like construction of roads for quick military movement and internal transportation, railway, post, telegraph, airplanes, canals, etc. As the colonizers stood to gain from these facilities, so did the local people.
(b) Spread of Education : For the sake of a prosperous business and propagation of Christianity and humanitarian interests, education was given a boost. Instead of importing educated people from their native places, the colonizers began to educate the local people for raising qualified manpower necessary in assisting administration.
(c) Intellectual Change : The people of the colonies got acquainted with the innovative ideas, technology, science, philosophy, literature, law and politics. Colonization also introduced the people to the principles of liberty, equality and fraternity and the philosophies of nationalism, socialism, communism and democracy. A progressive mind set was created by uprooting ignorance and blind faith by social reformers.
Thus, the Imperialism of European nations had constructive effects on world history.
