George Orwell's writing was significantly shaped by the historical context of the Spanish Civil War. His involvement in the war profoundly impacted his views on totalitarianism and propaganda, themes that permeated his later works. Orwell's first-hand experiences with the conflict led him to understand the manipulation of truth and the importance of political integrity. These insights culminated in his seminal works, such as "1984" and "Animal Farm," where he critiques oppressive regimes and illustrates the dangers of ideological extremes.
