The video discusses the impact of the Great Terror of 1937-1938, highlighting the arrest and execution of key figures like Trotsky and the political, social, and economic consequences of Stalin's purges.

The arrest and execution of a key figure in February 1940 marked the end of the Great Purge, led by Berrier, who succeeded him and continued the atrocities. Despite Stalin's ongoing use of terror, the period between 1937 and 1938 is recognized as the peak of the Great Terror.

The chapter discusses Leon Trotsky's exile in Europe and Mexico, where he continued to publish anti-Stalinist works despite facing multiple assassination attempts. It also explores the responsibility for the Great Purges, highlighting Stalin's major role and the impact on Soviet society.

The Great Terror had negative impacts on Soviet society, fostering fear, mistrust, and a climate of suspicion among individuals. Politically, Stalin successfully eliminated all opposition to his regime, solidifying his power and control. Economically, the purges led to a labor shortage and minor stagnation, but also contributed to the economy through forced labor camps.
