7.Andrew Jackson

Andrew Jackson (March 15, 1767 – June 8, 1845) was the seventh President of the United States (1829–1837). Based in frontier Tennessee, Jackson was a politician and army general who defeated the Creek Indians at the Battle of Horseshoe Bend (1814), and the British at the Battle of New Orleans (1815). A polarizing figure who dominated the Second Party System in the 1820s and 1830s, as president he destroyed the national bank and relocated most Indian tribes from the Southeast to west of the Mississippi River. His enthusiastic followers created the modern Democratic Party. The 1830-1850 period later became known as the era of Jacksonian democracy.[1]
Jackson was nicknamed "Old Hickory" because of his toughness and aggressive personality; he fought in duels, some fatal to his opponents.[2] He was a rich slaveholder, who appealed to the common men of the United States, and fought politically against what he denounced as a closed, undemocratic aristocracy. He expanded the spoils system during his presidency to strengthen his political base.
Elected president in 1826, Jackson supported a small and limited federal government. He strengthened the power of the presidency, which he saw as spokesman for the entire population, as opposed to Congressmen from a specific small district. He was supportive of states' rights, but during the Nullification Crisis, declared that states do not have the right to nullify federal laws. Strongly against the national bank, he vetoed the renewal of its charter and ensured its collapse. Whigs and moralists denounced his aggressive enforcement of the Indian Removal Act, which resulted in the forced relocation of thousands of Native American tribes to Indian Territory (now Oklahoma).
Historians consider his legacy as mixed. They acknowledge his protection of popular democracy and individual liberty for United States citizens, but criticize him for his support for slavery and Indian removal.

8.Martin Van Buren

Martin Van Buren (December 5, 1782 – July 24, 1862) was the eighth President of the United States (1837–1841). Before his presidency, he was the eighth Vice President (1833–1837) and the tenth Secretary of State, under Andrew Jackson (1829–1831).
He was a key organizer of the Democratic Party, a dominant figure in the Second Party System, and the first president not of British descent—his family was Dutch. He was the first president to be born an American citizen,[2] his predecessors having been born British subjects before the American Revolution. He is also the only president not to have spoken English as his first language, having grown up speaking Dutch,[3] and the first president from New York.
As Andrew Jackson's Secretary of State and then Vice President, he was a key figure in building the organizational structure for Jacksonian democracy, particularly in New York State. As president, he did not want the United States to annex Texas, an act which John Tyler would achieve eight years after Van Buren's initial rejection. Between the bloodless Aroostook War and the Caroline Affair, relations with Britain and its colonies in Canada also proved to be strained.
His administration was largely characterized by the economic hardship of his time, the Panic of 1837. He was scapegoated for the depression and called "Martin Van Ruin" by his political opponents. Van Buren was voted out of office after four years, losing to Whig candidate William Henry Harrison.
In 1848 he ran unsuccessfully for president on a third-party ticket, the Free Soil Party.
