Final answer:
In the early 20th century, around 700,000 European immigrants, notably Jews fleeing pogroms in Russia, migrated to the United States to find work and escape political upheavals and religious persecution.
Step-by-step explanation:
The phrase '700,000 ____ immigrants' refers to the massive influx of European immigrants to the United States in the early 20th century. During this period, many immigrants came to America to find work and flee political turmoil or religious persecution. One notable group among these immigrants was Jewish refugees escaping the pogroms in the Russian empire.
From the late 19th to the early 20th century, there was a significant increase in immigration to the United States. People from southern and eastern Europe, including many Jewish immigrants, sought new opportunities in America. They were drawn by the promise of work in the rapidly industrializing economy and the need to escape political and religious persecution in their own countries.
Led by immigrants from Italy, Greece, Russia, and the Balkans, this era saw over a million people arriving each year by 1905. Many settled in ethnic enclaves where they could maintain cultural practices, relish familiar food, and speak their native languages. By the early 1920s, it is estimated that around 2 million Jews had found a new home in the United States, as part of the broader European migration.
