The aim is to locate these Europeans in the structures we have already described in the previous chapter. In a possibly perverse way, what we intend to show is that the European presence over its first 250 years certainly varied from place to place and time to time, but overall the effects on the Indian Ocean, its trade, its people, even its politics, was limited. The next chapter deals in detail with continuing structures, which by and large the Europeans were forced to accommodate, or concerning which they had no knowledge at all. Here we will look not only at trade, the topic which so far has dominated the historiography of the Indian Ocean, but also at religious movements, and the social history of people on ships. Finally we will note how the Indian Ocean was now much more part of a wider world than had been the case in previous centuries. In the terms set out by Horden and Purcell, we increasingly have to write a history where the history in the ocean, that is a history which looks beyond its geographical bounds, is more important than an autonomous history of the ocean.
