what are a few events that took place from 1900-1920 that influenced the art movements?

PROMPT- In order to gain a perspective of the rapid changes in early-twentieth-century society and their direct relation to the plethora of art movements, I would like you to pick one year from 1900?1920. Research noteworthy inventions, world events, and discoveries from that year and tell how you think they influenced the art movements of the 20th century (Be specific- give examples). Write a script to follow and have pictures of what you are presenting open a head of time. The script should be about 4 minutes long for me to present. However, the quickest way I believe to get the photos ready is to place them in a power point. Let me know if you have any questions.
