Final answer:
The modern temper in American history refers to the cultural, social, and economic shifts during the 1920s, which some Americans resisted due to a preference for traditional norms. Nativism and fundamentalist movements arose in reaction to immigration and urbanization, while the Temperance Movement sought to address the social issues caused by alcohol consumption.
Step-by-step explanation:
The Modern Temper and Reactions Against It
In the context of American history, the modern temper refers to the societal shifts towards urbanization, industrialization, and cultural changes following World War I, particularly noticeable during the 1920s. This period was marked by a rise in consumerism, a quest for leisure, and a proliferation of new ideas about social norms and values. However, not all Americans were receptive to these transformations. Many, especially in rural areas, pushed back against what they perceived as threats to traditional ways of life. This pushback took various forms, from the emergence of nativism, which was fueled by high levels of immigration leading to feelings of racial animosity and anxiety among native-born Americans, to the criticisms by authors like Edward Bellamy and Thorstein Veblen, who felt the country was losing its moral compass in the face of industrial expansion.
The clash between the old and new was particularly vivid during the 1920s when the erosion of traditional norms led to the rise of fundamentalist philosophies and terror groups like the Second Ku Klux Klan. Highlighted by events such as the Sacco and Vanzetti trial and the Scopes trial, these reactions showcased Americans' fear of immigrants, radical politics, and the impact of scientific theories on Christian beliefs. Amidst all these social upheavals, the Temperance Movement gained momentum as a means to reform societal ills associated with the consumption of alcohol—which was seen as a cause of immorality and economic loss.
