A few suggestions on where/how to
1.) Women's rights -- the
two biggest things to happen in the 1920s
were women winning the right to vote and
Alice Paul introducing the Equal Rights
Amendment. Both gestures are key
to women's rights.
2.) On Labor Issues -- Rose Schneiderman
among others were key to this issue, including
protecting undocumented workers as well as
those trapped in low wage jobs with little
regulation, a reaction to the Triangle Shirtwaist
Fire among other trials.
3.) Native American
-- you should reference the work of Sally
Roesch Wagner to better assess what was specifically
happening at that time.
I hope these suggestions
lead you to further research. Good luck.
