Background: Many Americans like to imagine the history of their nation as one of continual progress. While acknowledging that not all persons and groups enjoyed equal rights at all times, Americans often take it for granted that American history moves in only one direction: toward greater rights, greater freedom, and greater equality. However, from roughly 1867 to 1875, African Americans enjoyed far more political influence and equal rights than they ever had before, or ever would again, until the end of the modern Civil Rights Movement almost a century later. In addition to the disturbance in the social hierarchy created by the end of slavery, the nation experienced the influx of huge numbers of immigrants during the last half of the 1800s, many of whom were viewed by the American population as different and inferior to earlier waves of immigrants. Adding to concerns about social order was the push for women’s suffrage that arose after Civil War. These factors came together to create a threat to White male supremacy and combined to create a period characterized by conflict over race, ethnicity, and gender.Review the following sources about the differences between primary and secondary sources:Primary, Secondary, Tertiary SourcesTranscriptHow to Research Primary SourcesHow to Research Secondary SourcesRequired sources:What is Freedom?—Freedom: A History of US in the Films on Demand database in the Ashford University LibraryAlien MenaceRecommended sources:Entertaining Citizenship: Masculinity and Minstrelsy in Post-Emancipation San FranciscoIdentity, Marriage, and Schools: Life along the Color Line/s in the Era of Plessy v.
