When did Germany invade Russia during World War II?

The invasion of Russia by Germany during World War II is famously known as Operation Barbarossa, which commenced on June 22, 1941. This date marks a significant turning point in the war, as it initiated a massive military campaign on the Eastern Front. The primary objective of the invasion was to capture key Soviet territory, eliminate the Soviet Union as a military power, and acquire resources.

The timing of the invasion was strategic; it aimed to catch the Soviet Union off guard after the Molotov-Ribbentrop Pact, a non-aggression treaty between the two nations, had created an illusion of peace. Germany's approach was characterized by rapid advance and significant initial successes, but the operation ultimately failed to achieve its goals and resulted in extended conflict, contributing to the eventual downfall of Nazi Germany.
