According to Estonian philosopher Jaan Kaplinski, the birth of anti-Russian sentiment in Estonia dates back to 1940, as there was little or none during the czarist and first independence period, when anti-German sentiment predominated. Kaplinski states the imposition of Soviet rule under Joseph Stalin in 1940 and subsequent actions by Soviet authorities led to the replacement of anti-German sentiment with anti-Russian sentiment within just one year, and characterized it as "one of the greatest achievements of the Soviet authorities". Kaplinski supposes that anti-Russian sentiment could disappear as quickly as anti-German sentiment did in 1940, however he believes the prevailing sentiment in Estonia is sustained by Estonia's politicians who employ "the use of anti-Russian sentiments in political combat," together with the "tendentious attitude of the media." Kaplinski says that a "rigid East-West attitude is to be found to some degree in Estonia when it comes to Russia, in the form that everything good comes from the West and everything bad from the East"; this attitude, in Kaplinski's view, "probably does not date back further than 1940 and presumably originates from Nazi propaganda."
