What role did the free soil party play in the election of 1848? ?

A faction of New York Democrats known as the Barn burners objected to slavery in the territories and opposed the 1848 Democratic nominee, Lewis Cass. The Barn burners and other anti-slavery Democrats joined with some anti-slavery Whigs and the Liberty Party to form the Free Soil Party. 

Hope it helps :)

The role that the Free-Soil Partyplayed in the election of 1848was that it won 10% of the vote by utilizing it's antislavery platform. Although the Free-Soil Party's candidate, Martin Van Buren, did not carry any states, he collected enough votes to cause Lewis Cass, the Democratic candidate, to lose

The Main Idea if the Summary is the Inequality in labor conditions, such as hourly pay and working benefits between Men and the minority group composed of Women and Children.

The Industrial Revolution, which started during the second half of the 18th century, brought many improvements in society, as it improved economic conditions of Women, who previously were limited to doing housework and earned much less in comparison to an hourly wage working at the factories.

However, improvements will be considered as such only for a limited period of time, as issues such as gender equality and labor conditions will start to come out as a result of the new realities of manufacturing industries in the country. These issues would later be addressed with the appearance of social movements whose purpose was to reduce the gap in gender inequality, as well as the appearance of labor unions, which lobbied in favor of improving working conditions for workers.
