What could the relation if any be between the expansion of peoples, empires and lattitude? Some northern peoples, from what I know about as the "eskimo-aleut" groups are spread over vast northern territories, from eastern parts of Siberia over Northern North America to Greenland. An Empire like the Russian expanded to one of the biggest ever. Both in general at high lattitudes, relatively closer to the North Pole than others. This makes less hours of night darkness, more of light for campaigns as well as other voyages and expeditions. Then also the freezing of water in wintertime may have helped groups of voyagers and explorers as well soldiers passing water. Rivers, lakes and even small parts of the Seas. So, could lattitudes have been more important than many of us think about?
