Explain how the election of Andrew Jackson in 1828 contributed to the development of the second party system in the United States.

I can describe how disagreements over government powers led to the formation of political parties.

1
The first party system in the United States included the Federalists, who supported a stronger national government, and the Democratic-Republicans, who were more skeptical of national power.

The issue of slavery led to the destruction of the Whig party and the rise of the Republican party, with Abraham Lincoln's election ushering in the third party system.
