One reason Andrew Jackson was considered a champion of the "common man" was because he fought in the War of 1812.

Explanation:

In the War of 1812, Jackson primarily fought against Native Americans from western Florida, including the Creek. These tribes resisted the American urge westward and the submission to the United States. Jackson, however, managed to defeat them and through the Treaty of Fort Jackson the Creek Indians ceded an area of ​​approximately 90,000 km² to the United States.

Jackson was also the American commander in the Battle of New Orleans (January 8, 1815). There he managed to inflict a crushing defeat on the British, but the battle was fought when an agreement had been reached in Ghent between the British and American governments. Due to the slow communication this was passed on too late to the troops near New Orleans, so that the armies still fought each other. By beating the British, Jackson gained national recognition. He was suddenly one of the most famous characters in the country and considered a war hero, a status that later benefited him during his attempt to become president.
