The goal was to find and map the eastern reaches of Siberia, and hopefully the western shores of North America. Peter I had a vision for the 18th-century Russian Navy to map a Northern Sea Route from Europe to the Pacific. This far-reaching endeavour was sponsored by the Admiralty College in St. Petersburg.
With over 3,000 people directly and indirectly involved, the Second Kamchatka Expedition was one of the largest such projects in history. Its cost, completely financed by the Russian state, reached an estimated 1.5 million rubles, an enormous sum for the time; roughly one sixth of the income of the Russian state in 1724.
The achievements of the expedition included the European discovery of Alaska, the Aleutian Islands, the Commander Islands, Bering Island, as well as a detailed cartographic assessment of the northern and north-eastern coast of Russia and the Kuril Islands. It definitively refuted the legend of a land mass in the north Pacific, and did ethnographic, historic, and scientific research into Siberia and Kamchatka. When the expedition failed to round the north-east tip of Asia, the dream of an economically viable Northeast passage, sought since the 16th century, was at an end.
Systematic exploration and scientific discovery in the eastern part of Asia was at the initiative of Tsar Peter the Great (1672–1725). In 1697 and 1698, he traveled in a number of European nations, and became enthused at the idea of a scientific academy in Russia. In 1723/24, he drew foreign scholars to St. Petersburg, hoping to replicate the scientific culture of Europe in his own land and to educate native scholars.
In December 1725, the institution was inaugurated with celebrations. Young, mostly German-speaking scholars formed the core of the Academy in its first decades. One of their tasks was to organize and eventually accompany scientific expeditions to then-unexplored parts of the empire. During Peter’s lifetime, the German doctor Daniel Gottlieb Messerschmidt (1685–1735) traveled from 1720 to 1727 to western and central Siberia. This was the beginning of investigation in geography, mineralogy, botany, zoology, ethnography, and philology there, as well as an opening-up of the region to trade. Messerschmidt's Expedition was the first in a long series of scientific explorations of Siberia.
