Final answer:
Andrew Jackson and Martin Van Buren played significant roles in forming the two-party system in the United States. Jackson's presidency and the emergence of the Democratic Party established the foundation for the system, while Van Buren's victory solidified it.
Step-by-step explanation:
The role of Jackson and Van Buren in forming the two-party system in the United States is significant.
Firstly, Andrew Jackson's presidency and the emergence of the Democratic Party in 1828 laid the foundation for the two-party system. Jackson's vision of empowering the common citizen and his focus on states' rights resonated with the Democrats, who believed that the government should reflect the will of the majority.
Secondly, Martin Van Buren, as a key figure in the creation of the Democratic Party and as Jackson's advisor, played a crucial role in promoting and furthering Jacksonian principles as the president. Van Buren's victory in the 1836 presidential election solidified the two-party system, with the Democrats representing the majority's interests.
