European governments expanded their powers
Drafted millions of young men
Used propaganda to get more to join the military

Planned Economies
Gov’t set up price, wage, and rent controls
Rationing- limit consumption of resources/goods
Took over transportation systems
Took over factories to produce military goods

35. WWI Impact on Society
Influenza (1918) killed 50 million people world wide
New roles for women in the workforce
Immediately after the War women get the right to vote

36. Activity #2: Cause and Effect
