Which of the primary features of grassroots progressivism was the most essential to the continued growth and success if the reformist movement?  

1. It helps to raise money

2. Deepens political participation

3. It help to raise awareness massively.

Explanation:

grassroots movements aim to raise money, build organizations, raise awareness, build name recognition, to win campaigns, and to deepen political participation.

In the modern era, a movement that identifies as progressive is "a social or political movement that aims to represent the interests of ordinary people through political change and the support of government actions In the 21st century, those who identify as progressive may do so for a variety of reasons: for example, to favor public policy that reduces or ameliorates the harmful effects of economic inequality as well as systemic discrimination, to advocate for environmentally conscious policies, as well as for social safety nets and rights of workers, to oppose the negative externalities inflicted on the environment and society by monopolies or corporate influence on the democratic process.

here are some major conflicts i found. maybe pick one and do more research on it. (cause i ain't writing 6 paragraphs)

in 1877, the nez perce war took place.

1881 - president james garfield was assassinated.

1882 - the chinese exclusion act was passed.

1883 - a decision in the civil rights cases legalized racial segregation in the united states.

1887 - the dawes act was passed.

1893 - the panic of 1893 took place. (what a creative name)

and there are probably other topics you can find if you just search up "united states timeline," or "conflicts in the 19th century for america."

then once you find a topic you like find out how it affected the people of america and what not. (sorry if this feels a bit short changed, history was and never will be one of my strong topics)
