"The political fortunes of Moscow were closely connected with its geographical position." "Thus Moscow arose at the point of intersection of three great land roads - a geographical position which conferred important economic advantages upon the city and its neighborhood. ...Boyars always followed the currents of popular migration, so that their genealogical records are evidence that at that period [time of Daniel, youngest son of Alexander Nevsky, circa 1270 AD.] the general trend was toward Moscow. This steady influx into the city, as into a central reservoir, of all the Russian popular forces threatened by external foes was primarily due to the geographical position of Moscow."
