I want to change the way you see the world. Specifically, I want to change the way you see the world map by focusing your attention on the blues that shade
70 percent of the image before you, and letting the earth tones fade. This shift in emphasis from land to water makes many trends and patterns of world history stand out in ways they simply cannot otherwise. Before the development of the locomotive in the nineteenth century, culture, commerce, contagion, and conflict generally moved faster by sea than by land. The opening of sea routes sometimes resulted in immediate transformation, but more often it laid the groundwork for what was later mistaken for sudden change. The best example of this is the trade networks of the Indian Ocean, the oldest of which were pioneered at least four thousand years ago by navigators sailing between Mesopotamia and the mouths of the Indus River. By the start of the common era two thousand years ago, the Indian subcontinent was a point of departure and destination for merchants and mendicants from across the Arabian Sea and the Bay of Bengal. This is all but unnoticed in the written record, which boasts of no figure comparable to a Gilgamesh or Odysseus, and despite a growing body of archaeological evidence, these undertakings remain largely unrecognized. As a result, the later arrival in Southeast Asia of Muslim traders from the Indian subcontinent and Southwest Asia, of Chinese merchants of various faiths, and of Portuguese Christians seem like so many historical surprises. Only the last were absolute newcomers to the Monsoon Seas that stretch from the shores of East Africa to the coasts of Korea and Japan. The others were heirs to ancient, interlinked traditions of seafaring and trade that long ago connected the shores of East Africa with those of Northeast Asia. This book shows many similar examples of maritime regions that were quietly exploited before events conspired to thrust them into the historical limelight.

Two questions merit consideration before taking on a maritime history of the world as either writer or reader: What is maritime history? and What is world history? The answers to both have as much to do with perspective as with subject matter. World history involves the synthetic investigation of complex interactions between people of distinct backgrounds and orientations. It therefore transcends historians’ more traditional focus on politically, religiously, or culturally distinct communities seen primarily in their own terms at a local, national, or regional level. As a subject of interdisciplinary and interregional inquiry, maritime history is a branch of world history that covers obvious topics like shipbuilding, maritime trade, oceanic exploration, human migration, and naval history. Considered as a perspective, however, the premise of maritime history is that the study of events that take place on or in relation to the water offers unique insights into human affairs. The maritime historian therefore draws on such disciplines as the arts, religion, language, the law, and political economy.

An alternative and perhaps simpler way to approach the question, What is maritime history? is to tackle its unasked twin: What is terrestrial history?— the view from the land being our default perspective. Imagine a world of people bound to the land. The ancient Greek diaspora would have taken a different character and been forced in different directions without ships to carry Euboeans, Milesians, and Athenians to new markets and to sustain contacts between colonies and homelands. Without maritime commerce, neither Indians nor Chinese would have exerted the substantial influence...
