Women became leaders in a range of social and political movements from 1890 through 1920. Progressive reformers wanted to end political corruption, improve the lives of individuals, and increase government intervention to protect citizens. The suffrage movement was part of this wave of Progressive Era reforms.
Progressive reforms tried to protect women in the workplace numerous ways. One of these ways was limiting how many hours women, along with children, could work. A couple states ended up passing set hours women could work at their job, but did not set the same for men. This ended up hurting women more than helping them, as many working women were single parents or needed to make money to help their family, so setting how many hours they could work would hurt them greatly. The working conditions also started to improve and became less dangerous over time, which protected women and helped them stay safe.
A common factor that triggered the hot wars in Asia was based on communism. The United States wanted to halt the spread of communism while the Soviet Union wanted to influence every region and make them communists.
There were protests mainly against police brutality and systemic racism. Much like the MLKJr movement for the equality of people in the U.S. this was also followed with a small amount of unrest. But they are justified in what they want from the country and they have every right guaranteed by the constitution to assemble and protest.
