1920-1930

= **1920-1930 A** =
 * Intro:** Without inventions discovered in 1920 - 1930, we would not have the technology we have today. Imagine life with movies without any sound, transportation without cars, paper cuts without band-aids. It was the 1920's where major inventions were created. In the 1920s - 1930s, technology, entertainment, and economy and politics all drastically changed. In the technological area, Ford cars, band-aids, and the lie detector were created. The technology developed in the 1920s enables people to prevent infects after cuts, escaping from punishment after committing crime, and save energy by driving a car. Changes in the entertainment areas are films with sound, the famous Charleston dance, and the publish of major magazines that still exists today. Political changes include the constitutional amendment: the rights for women to vote, the black plague spreading in India, and the increase inflation in Germany.
