The Democratic Party is the world's oldest political party and can trace its history back to Thomas Jefferson and James Madison's Democratic-Republican Party.

The modern-day Democratic Party was founded in 1828 by supporters of Andrew Jackson, drastically changing its ideology around the turn of the 20th century to become the major liberal or left leaning party of the United States of America, effectively swapping ideologies with its rival, the Republican Party.
