Since the easiest and cheapest way of long-distance travel was by sea, international trading networks emerged in the Atlantic World, with major hubs at London, Amsterdam, Boston, and Havana.
The West Coast and Central Africa, which are distinct from one another and each made up of many competing polities, played core roles in shaping the Atlantic World and as major sources for slave labor.
The main empires that built the Atlantic World were the British,[9] French,[10] Spanish[11] , Portuguese[12] and Dutch;[13] entrepreneurs from the United States played a role as well after 1789.
American historian Bernard Bailyn traces the concept of the Atlantic World to an editorial published by journalist Walter Lippmann in 1917.
[15] The alliance of the United States and Great Britain in World War II, and the subsequent creation of NATO, heightened historians' interest in the history of interaction between societies on both sides of the Atlantic Ocean.
[16] Other scholars emphasize its intellectual origins in the more systematic and less political approach of the French Annales school, especially the influential work by Fernand Braudel on the Mediterranean World (trans.
Atlantic World history emphasizes how the colonization of the Americas reshaped Africa and Europe, provided a foundation for later globalization, and insists that our understanding of the past benefits from looking beyond the nation state as our primary (or sole) category of analysis.
[citation needed] The beginning of extensive contact between Europe, Africa, and the Americas had sweeping implications for the environmental and demographic history of all the regions involved.
The epidemiological impact of this exchange on the indigenous peoples of the Americas was profound, causing very high death rates and population declines of 50% to 90% or even 100%.
[20] As European powers began to conquer and claim large territories in the Americas in the 16th and 17th centuries, the role of chattel slavery and other forced labor systems in the development of the Atlantic World expanded.
[21] In short, the Atlantic World was one of widespread inequality where the exploitation of human labor provided the foundation for a small handful of elites to reap enormous profits.
The Trans-Atlantic Slave trade played a massive role in shaping the demographics of the Americas, especially in areas where huge plantations were the norm, such as in Brazil and the Caribbean.
In many cases, European authorities viewed spiritual positions that were highly esteemed in African societies to be socially unacceptable, morally corrupt, and heretical.

The early Spanish conquerors of these empires were also aided by political instability and internal conflict within the Mexica and Incan regimes, which they successfully exploited to their benefit.
[29] Britain approached the task of governing its New World territories in a less centralized manner, establishing about twenty distinct colonies in North America and the Caribbean from 1585 onward.
