 With the discovery of the American continent or 'New World' in 1492–1493, the European colonial Age of Discovery and exploration was born, revisiting an imperialistic view accompanied by the invention of firearms, while marking the start of the Modern Era.During this long period the Catholic Church launched a major effort to spread Christianity in the New World and to convert the Native Americans and others.A 'Modern West' emerged from the Late Middle Ages (after the Renaissance and fall of Constantinople) as a new civilization greatly influenced by the interpretation of Greek thought preserved in the Byzantine Empire, and transmitted from there by Latin translations and emigration of Greek scholars through Renaissance humanism.
