Final answer:
In response to rising anti-Semitism in Europe, particularly violent in Tsarist Russia, many Jewish people migrated to the United States in the 1880s, forming significant communities and establishing organizations to combat persecution.
Step-by-step explanation:
In the late 19th century, anti-Semitism became prevalent in Europe, prompting many Jewish individuals to seek refuge elsewhere. The 1880s saw the rise of nationalist sentiments and economic insecurities, which often translated into a scapegoating of Jewish communities. These sentiments were especially violent in Tsarist Russia, where pogroms--organized massacres and attacks against Jews--became frequent. Jews were restricted in their rights, often portrayed as the cause of a variety of societal ills, and faced violent backlash, including from political parties that emerged around anti-Semitic ideologies. The situation led to a significant migration of Jewish people, particularly from the Russian Empire.
While some of these individuals migrated to places like Palestine or Britain, it was the United States that became a major destination. Jewish leaders such as Jacob Schiff played crucial roles in helping to establish communities and protect against anti-Semitism in the US. The American Jewish Committee and the Anti-Defamation League were founded in response to these challenges.
Overall, the response to the increasing anti-Semitism of this period was a significant migration, with many finding new homes in the United States, contributing to the development of Jewish life that shifted from Eastern Europe to places like New York, Philadelphia, and Baltimore.
