Answer:
The Know-Nothing Party was established in 1850.
In July of 1844, riots broke out in the city of Philadelphia. Nativists battled Irish immigrants which resulted up to two Catholic churches and a Catholic school being burned down.
The Know-Nothing Party was was an outgrowth of the strong anti-immigrant people.
In 1843, The Know-Nothings formed the American Republic Party.
1854 they had allied themselves with groups within another political party called the Whigs.
In 1855, The Know-Nothings dropped much of their secrecy and became known as the American Party.
FREE-SOILER PARTY
The Free-Soiler Party was a short political party in the US during 1848-1852 presidential elections
It was the 3rd largest party that grew it's greatest strength from New York.
The party leadership consisted of former anti-slavery members of the Whig Party and the Democratic Party.
Its main purpose was opposing the expansion of slavery into the western territories, arguing that free men on free soil comprised a morally and economically superior system to slavery.
Its presidential nominee in 1848, Martin Van Buren, received 291,616 votes against Zachary Taylor of the Whigs and Lewis Cass of the Democrats, but Van Buren received no electoral votes. The Party's "spoiler" effect in 1848 may have put Zachary Taylor into office in a narrowly-contested election.
The Compromise of 1850 temporarily neutralized the issue of slavery and undercut the party's no-compromise position. Most Barnburners returned to the Democratic party, and the Free Soil Party became dominated by ardent anti-slavery leaders.
The Free Soil Party was a notable third party. More successful than most, it sent two Senators and fourteen Representatives to the thirty-first Congress, which convened from March 4, 1849 to March 3, 1851.
