Answer:
Firstly, the influx of immigrants during the 19th century created a sense of fear and unease among native-born Americans. Many of these immigrants came from different countries and cultures and brought with them their own traditions and beliefs. This created a sense of cultural clash, and many Americans felt that their way of life was being threatened by the presence of these new groups.
Secondly, the rise of urbanization also led to conflicts between different groups of people. As more people moved into the cities, competition for jobs and resources became increasingly fierce. This led to tensions between different ethnic and racial groups, as well as between different social classes.
Finally, these conflicts were further exacerbated by the rise of nativism, which was a political ideology that sought to protect the interests of native-born Americans. Many nativists saw immigrants as a threat to their way of life, and they used fear and propaganda to stoke anti-immigrant sentiment.
Overall, I think immigration and urbanization played a significant role in creating conflicts between different groups of people in the 19th century. These conflicts were further fueled by the rise of nativism, which sought to protect the interests of native-born Americans and saw immigrants as a threat to their way of life. The evidence from the videos supports this view, and I think this is an important lesson for us to remember today, as we continue to grapple with issues related to immigration and diversity.
