By 1852 they were a full-fledged political party, known as the American party.
While "reformism" only became a practical issue in the American party in 1910, it had its beginnings much earlier.

"ignoramus," 1827, from know + nothing. As a U.S. nativist political party, active 1853-56, the name refers to the secret society at the core of the party, about which members were instructed to answer, if asked about it, that they "know nothing." The party eventually merged into the Republican Party.
