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.
Genuine Republican Party
The Genuine Republican Party (, PRG) was founded in Bolivia in 1921 by José María Escalier and Daniel Domingo Salamanca Urey following a split in the Republican Party.
Genuine Republican Party was formed by a conservative sector. The Republican Government of Bautista Saavedra enacted progressive social and labor codes and doubled government taxes on mining. Frightened, the urban upper class and traditional rural and regional elites rallied around Daniel Salamanca, a Cochabamba Department landowner and old-style patrician.
The program of this party advocated recovery of Bolivian territory and freedom of speech.
In May and December 1925 Daniel Domingo Salamanca Urey unsuccessfully ran in the presidential elections.
