Final answer:
The parties from the Jacksonian Era were split by the Second Party System, with the Democrats supporting Andrew Jackson and advocating for the common people, and the Whigs promoting economic development. Slavery and its expansion ultimately led to the end of the Whigs and the second party system.
Step-by-step explanation:
The parties from the Jacksonian Era were finally split by the emergence of the Second Party System, which began with the splitting of the Democratic-Republicans and the formation of two new political parties. One half, the Democratic Party, was the party of Andrew Jackson, advocating for the common people and opposing a national bank.
The other half, initially known as the National Republicans and later becoming the Whig Party, believed in national government's role in economic development. However, the question of slavery and its expansion westward ultimately led to the demise of the Whigs and the second party system in the 1850s.
