Answer: incorporated into state and federal laws

Explanation:

The People's Party (also known as the Populist Party), was founded in 1891 in an attempt to protect the political and economic interests of the agricultural sector and its farmers.

They fought for an increase in the circulating currency, which led to the unlimited coinage of silver, for a graduated income tax, the direct election of U. S. senators, and many laws intended to strengthen democracy and promote parity between farmers and business and industry.
