Explanation:

The Progressive Era heralded a period of activism and political reform in the United States during the late 80's and early 90's.

The Progressive era was meant to remove corrupt public officials from office, adressing issues caused by immigration, urbanisation, etc so that a more direct democracy would be enforced.

Some of the reforms that came about because of this movement include imposition of income tax, direct election of senators, laws to tackle election fraud, etc.
