Why is it considered that colonial period was the period of renaissance for the people of India?

History of Europe tells us that Italy was the first country where the wave of renaissance were felt. It further tells us that Greeks had to suffer extermination and carnage in the hands of Turks in 145 BCE. These people fled from greece to seek refuge in Italy and they lit the torch of their knowledge there. By referring the European background, we want to explain that Enlightenment or wisdom receives resplendence only when troubles of complex nature are faced by mankind. Much or less the same has happened in India during colonial rule. They were insulted, suffered coercion, extortion and merciless killing during British regime but in, the lap of that gross darkness, they could understand importance of living a life in cooperation, harmony, tolerance and maintaining unity all over the country. Thus, we can say that it was colonialism which gave birth to nationalism viz. a sheer allegiance to a nation or patriotism. The shared experience of colonial domination helped in understanding the value of unity and energised different sections of the community. The emerging middle classes begem, with the help of western style education to challenge colonialism on its own ground. The interferences created by colonialism in the public and private life of Indian people had crystallised religious and caste based communities.
