The Election of William Henry Harrison in 1840 marked a significant political shift in the United States, as it was the first election where a candidate effectively used modern campaign techniques, leading to Harrison's victory over incumbent Martin Van Buren. This election showcased the rise of the Whig Party and was characterized by a focus on appealing to the common man, with slogans and rallies that energized voters. Harrison’s presidency was cut short by his untimely death just weeks after his inauguration, leading to John Tyler assuming the presidency and setting precedents for presidential succession.
