Final answer:
The Jacksonian Era is dubbed the Era of the Common Man because it expanded democracy to nearly all white men, but this did not extend to minorities, and it was marked by both increased electoral access and policies favoring the interests of common white men.
Step-by-step explanation:
The Jacksonian Era is also called the Era of the Common Man because it was characterized by the extension of democracy to nearly all white men, an increase in elective government positions, and the creation of a political environment that valued the image and rights of the common white man. However, it is essential to note that this era also saw the mass removal of Indians from their homelands and increasing tensions over slavery, which highlighted a significant limitation in the equality the era purported to champion for all. Andrew Jackson's actions as president, such as using the spoils system and promoting a vision that seemed to primarily benefit his white male constituency, also contributed heavily to this characterization.
