Question

mention the effects of first world war on russia

Answer 1

WORLD WAR I affected the RUSSIAN FEDERATION in terms of huge human & material losses in mostly lost battles, economic crisis, a complicated many-sided civil war of appalling bloodiness, wars of independence fought by subject nations (some successfully, some not), foreign intervention, famine, pogroms, epidemics, mass slaughter of real & imagined political opponents by security services of various sides, & the flight of at least hundreds of thousands.

And of course, revolution.

By 1921 the total income of the territory within the boundaries of the post-war USSR was about 40% of its pre-war level. The population of the current territory of Russia is estimated to have dropped by 13 million between 1914 & 1920, & many more had died in what are now Ukraine, Belarus, the Baltic states, & Poland.
