the Don Cossacks led by Stenka Razin initiated a major uprising in the Volga region, but the Tsar's troops were successful in defeating the rebels. In the east, the rapid Russian exploration and colonisation of the huge territories of Siberia was led mostly by Cossacks hunting for valuable furs and ivory. Russian explorers pushed eastward primarily along the Siberian river routes, and by the mid-17th century there were Russian settlements in the Eastern Siberia, on the Chukchi Peninsula, along the Amur River, and on the Pacific coast. In 1648 the Bering Strait between Asia and North America was passed for the first time by Fedot Popov and Semyon Dezhnyov. Discovery and trade The Age of Discovery was a period from the early 15th century and continuing into the early 17th century, during which European ships traveled around the world to search for new trading routes and partners to feed burgeoning capitalism in Europe. They also were in search of trading goods such as gold, silver and spices. In the process, Europeans encountered peoples and mapped lands previously unknown to them. This factor in the early European modern period was a globalizing character; the 'discovery' of the Americas and the rise of sustained contacts between previously isolated parts of the globe was an important historical event. The search for new routes was based on the fact that the Silk Road was controlled by the Ottoman Empire, which was an impediment to European commercial interests, and other Eastern trade routes were not available to the Europeans due to Muslim control. The ability to outflank the Muslim states of North Africa was seen as crucial to European survival. At the same time, the Iberians learnt much from their Arab neighbors. The northwestern region of Eurasia has a very long coastline, and has arguably been more influenced by its maritime history than any other continent. Europe is uniquely situated between several navigable seas, and intersected by navigable rivers running into them in a way that greatly facilitated the influence of maritime traffic and commerce. In the maritime history of Europe, the carrack and caravel both incorporated the lateen sail that made ships far more maneuverable. By translating the Arab versions of lost ancient Greek geographical works into Latin, European navigators acquired a deeper knowledge of the shape of Africa and Asia. Mercantile capitalism Mercantilism was the dominant school of economic thought throughout the early
