Final answer:
The period between 1800 and the 1920s was indeed a period of great inequality, and saw a resurgence of the Ku Klux Klan and the enactment of Jim Crow laws.
Step-by-step explanation:
The statement in the question, 'The period between 1800 and the 1920s was a period of great inequality - like today - and saw a dramatic resurgence of the Ku Klux Klan and the enactment of Jim Crow laws,' is true. During this period, there was indeed a significant increase in inequality, the Ku Klux Klan experienced a resurgence, and Jim Crow laws were enacted.
Following the Civil War and the abolition of slavery, African Americans faced widespread discrimination and violence, particularly in the South. Jim Crow laws were implemented to enforce racial segregation and further marginalize African Americans. The Ku Klux Klan, a white supremacist group, terrorized black communities and targeted those who sought equality.
Ultimately, this period of inequality and racial hostility was a dark chapter in American history that contributed to social and political divisions that are still felt today.
