The Communist International, also known as the Third International or Comintern, was an organization founded in 1919 to promote worldwide communism. It aimed to unite various communist parties and movements across different countries, encouraging them to work towards the establishment of a global socialist society. The Comintern was closely associated with the ideas of Karl Marx and Vladimir Lenin, advocating for revolutionary action to overthrow capitalist systems. The organization played a significant role in international politics during the early 20th century, influencing various communist parties, including those in Germany, China, and France. However, it faced challenges and internal conflicts, leading to its eventual dissolution in 1943. The Comintern's legacy continues to impact leftist movements and discussions about socialism today.
