Where did the symbols for the democratic and republican parties come from?

Jackson, a hero of the War of 1812 who later served in the U.S. House of Representatives and U.S. Senate, was amused by being called a jacka** from his opponents, and included an image of the animal in his campaign posters. He later went on to defeat incumbent John Quincy Adams, and serve as America’s first Democratic president. In the 1870s, influential political cartoonist Thomas Nast helped popularize the donkey as a symbol for the Democratic Party. For the republican party, it was formed in 1854 and six years later Abraham Lincoln became its first member elected to the White House. An image of an elephant was featured as a Republican symbol in at least one political cartoon and a newspaper illustration during the Civil War.

Hope this helps and have a nice day!
