Such splintering had not yet led to formal party organization, but later the faction led by Andrew Jackson would evolve into the Democratic Party, while the factions led by John Quincy Adams and Henry Clay would become the National Republican Party and later the Whig Party.

Another remnant led by John Quincy Adams and Henry Clay formed the National Republicans in 1828; it developed into the Whig Party by 1835.
