Massachusetts Republican Party
The Massachusetts Republican Party was founded in 1854. Drawing together abolitionist and nativist anti-Catholic elements, it quickly became the dominant political force in the state and a powerful arm of the national Republican Party. Significant founding figures include Senator Charles Sumner, formerly of the Free Soil Party, and Speaker of the House Nathaniel Prentiss Banks, formerly of the American Party. 
At the time of the Republican Party's founding in 1854, all of Massachusetts's congressional representatives but Sumner were members of the nativist Know-Nothing Party. However, Banks's role as chairman of the 1856 Republican National Convention, his active support for the Republican presidential nominee John C. Frémont in 1856 and his focus on anti-slavery legislation as Speaker put him at odds with his party. Following the Democratic victory in the 1856 elections and the Dred Scott case in 1857, the national American Party organization collapsed, and most Northern members joined the nascent Republicans. In 1857, Banks ran as a Republican against incumbent Know-Nothing Governor Henry J. Gardner and won a decisive victory.
North Carolina Republican Party
With North Carolina a one-party Democratic state of the Solid South following the disfranchisement of blacks, North Carolina Republicans struggled to survive as a party during the first half of the twentieth century. African Americans were virtually excluded from the political system in the state until the late 1960s. In 1928 Republicans carried the state's electoral votes for president (for candidate Herbert Hoover). White members of the Republican Party generally lived in the Piedmont near Charlotte and Winston-Salem, and the mountains in the western part of the state. In 1952 Charles R. Jonas was elected to Congress from the western part of the state as the first Republican since before the Great Depression. He was joined in 1962 by Jim Broyhill. From this base, and nearly winning the electoral votes for the state in the Presidential elections from 1952 to 1960, the party began to grow.
