IOTL, Russia was always considered too Asiatic or Eastern since atleast the medieval ages for a number of factors.
I'm not sure that Catherine II or her successors would agree with that notion and, anyway, status of the Great Power (at least in the XVIII - XIX) more or less implied being "Western".
But how can a timeline where Russia is considered part of the West effect the world ?
Why and how would anybody care and why would it matter at all?
Maybe Russia becomes part of the European enlightenment and renaissance and later the industrial revolution?
Depending upon the historian, the age of enlightenment starts anywhere between 1620 and 1715 with the end of it (according to the French) being 1789 (quite fitting
). While the 1st date is definitely too early, the 2nd fits quite well, especially according to Voltaire and other French philosophers "stimulated" by Catherine II). Renaissance is a little bit more difficult because it is rather vaguely defined outside the area of arts and even in that area it is varying from country to country in its form and scope. Anyway, it was introduced in Russia by Ivan III in the late XV (pretty much Italian time line) who imported a number of Italian architects to build the
Cathedral of the Dormitionin the
Moscow Kremlin, the fortifications of the Moscow Kremlin and a number of churches and palaces like the Palace of Facets (below).
By the XVII century, Renaissance influenced drastic changes in the traditional icon paintings, making them more realistic, and even in development of secular portrait painting. Printing was 1st time introduced in the XVI century and became wide-spread by the XVII, modern canon casting adopted in the 15th century. Allegedly, the 1st sample of aqua vitae had been brought to Russia in 1386 by the Genovese with the 1st documented Russian vodka being produced in 1430 (not sure what other sign of the technological progress one would need
). As for the non-critical technological developments (like railroads, process mechanization, etc.) for quite a while they did not make too much sense economically because manual work force was widely available and cheaper. As an ultimate extension of this solid principle of getting the same results with the minimal expenditures, allegedly some Soviet general, when explained that computer can do a lot of calculations, remarked that the same result could be achieved much cheaper by giving few thousand soldiers (free labor) manual calculators.
