Posted on Dec 6, 2024 in History

1. The Russian Revolution (1905-1922)

The First Stages

Driven by Marxist ideals, the revolution aimed to establish a state as an alternative to Western democracy and capitalism. A socialist economic system was envisioned, with the economy centrally planned and politically integrated. The Bolsheviks, a single political party, led the movement against the Tsarist government.

  • 1905: The first revolutionary attempt failed.
  • Spring 1917: The Tsar was overthrown, with hopes of transforming Russia into a more European-style country.
  • October 1917: The Bolshevik revolution succeeded.

Aftermath

1917-1922: A civil war ensued, with the Communists ultimately proclaiming the Soviet Union (USSR). The Tsar and his family were executed.

Prosperity and Change

The USA became the world’s leading economic power, surpassing Great Britain. Social changes were significant:

  • The middle class enjoyed a period of prosperity.
  • Mass culture flourished with radio, cinema, and sports.
  • Women’s rights advanced, including the right to vote.

Economic Crisis

The era ended with the 1929 economic crisis, triggered by the Wall Street Crash. The crisis spread globally, impacting countries dependent on US trade and investment. Consequences included:

  • Factory and bank closures
  • Crop abandonment
  • Widespread poverty and hunger
  • Declining living standards

Solutions

The New Deal in the US implemented government changes, public works investments, agricultural aid, and measures to reactivate consumption. The crisis hit Europe in the 1930s, leading to unemployment, closures, political instability, and the rise of extremist ideologies. This turbulent period set the stage for the Spanish Civil War (1936-1939) and World War II (1939-1945).
