Historians in recent decades have argued that from a worldwide standpoint, the most important feature of the early modern period was its globalizing character. The period witnessed the exploration and colonization of the Americas and the rise of sustained contacts between previously isolated parts of the globe. The historical powers became involved in global trade, as the exchange of goods, plants, animals, food crops, and slaves extended to the Old World and the New World. The Columbian Exchange greatly affected the human environment.
New economies and institutions emerged, becoming more sophisticated and globally articulated over the course of the early modern period. This process began in the medieval North Italian city-states, particularly Genoa, Venice, and Milan in the west, and in India's Bengal in the east. The early modern period also included the rise of the dominance of the economic theory of mercantilism. The European colonization of the Americas, Asia, and Africa occurred during the 15th to 19th centuries, and spread Christianity around the world.
Other notable trends of the early modern period include the development of experimental science, accelerated travel due to improvements in mapping and ship design, increasingly rapid technological progress, secularized civic politics, and the emergence of nation states. Historians typically date the end of the early modern period when the French Revolution of the 1790s began the "late modern" period.
