Final answer:
The Second Great Awakening had a profound effect on minority groups in America, attracting them to the new Protestant denominations and empowering them. However, there were still limitations to spiritual equality.
Step-by-step explanation:
The Second Great Awakening had a significant impact on minority groups in America. The movement emphasized individual responsibility and the desire for perfection, which resonated with marginalized communities. The new Protestant denominations, such as the Baptists and Methodists, preached spiritual equality, attracting African Americans and women to join their churches. While the movement had empowering effects, there were still limits to spiritual equality, leading some African Americans to establish their own evangelical denominations.
