This study is intended to give a short survey on the development of shipping and trade between two main German ports and the Indian Ocean from the early years of the Bismarck period to the beginning of the First World War. The study deals with the area from East Africa to East India and from Indochina to Indonesia. China, the Philippines, and Australia will not be considered. It is based on an analysis of published material.

Portuguese Nyasaland is the name given to the most northern part of Portuguese East Africa, lying between Lake Nyasa and the Indian Ocean. It is separated from the Tanganyika territory in the north by the River Rovuma and from the Portuguese province of Mozambique in the south by the River Lurio. The territory measures about 400 miles from east to west and 200 miles from north to south and has an area of nearly 90,000 square miles. This territory is now perhaps the least known part of the once Dark Continent, but while the writer was actually engaged in the exploration of this country in 1920–1, the Naval Intelligence Division of the British Admiralty published two handbooks, the Manual of Portuguese East Africa and the Handbook of Portuguese Nyasaland, which with their extensive bibliographies contained practically everything that was known of that country up to that date (1920). These handbooks make it unnecessary in this paper to give detailed accounts of the work of previous explorers.

Almost forty years ago, the author published an article on Gujarat and East Africa from the sixteenth to the nineteenth centuries. Although several other scholars had written serious historical works either about or including Indian traders in eastern Africa in the modern period, at the time it was a pioneering piece for historians of East Africa. While the author has written and continues to write about the African diaspora in the Indian Ocean world and, more recently, the islands of this vast oceanic space now referred to as Indian Ocean Africa, he has not again written anything specifically about Gujarat and the Indian Ocean, nor about Gujarati traders in East Africa. This chapter attempts to review the last forty years of scholarship written in English on Gujarat and the Indian Ocean with a focus on transregional trade and traders. What is hoped from this overview is a sense of how current debates have developed over these decades and where further research is called for.

Comparable Size

The Indian Ocean has for at least two thousand years served as a highway for the exchange of goods and ideas, and the cultural links between the lands bordering it are perhaps closer than over any other region of comparable size. The length of voyages undertaken since early times has been very great, as is forcefully demonstrated by the Indonesian colonization of Madagascar in the first centuries A.D. Commerce has been facilitated by the monsoon which in the western part of the ocean blows for roughly half the year from the northeast and for half in the opposite direction. The eastern and western shores of the western part of the basin share much the same climate and are suited to similar ways of life.

The Impact

Timing and magnitude of surface uplift are key to understanding the impact of crustal deformation and topographic growth on atmospheric circulation, environmental conditions, and surface processes. Uplift of the East African Plateau is linked to mantle processes, but paleoaltimetry data are too scarce to constrain plateau evolution and subsequent vertical motions associated with rifting. Here, we assess the paleotopographic implications of a beaked whale fossil (Ziphiidae) from the Turkana region of Kenya found 740 km inland from the present-day coastline of the Indian Ocean at an elevation of 620 m. The specimen is ∼17 My old and represents the oldest derived beaked whale known, consistent with molecular estimates of the emergence of modern strap-toothed whales (Mesoplodon). The whale traveled from the Indian Ocean inland along an eastward-directed drainage system controlled by the Cretaceous Anza Graben and was stranded slightly above sea level. Surface uplift from near sea level coincides with paleoclimatic change from a humid environment to highly variable and much drier conditions, which altered biotic communities and drove evolution in east Africa, including that of primates.
