White flight
Following the turn of the century, Assyrian immigration to America mostly came to a halt due to the Immigration Act of 1924 which effectively cut off any legal immigration to the United States for Assyrians and other non-Western European groups. The second large wave of immigration occurred in the 1960s and 70s, mainly from northern Iraq due to conflicts and persecution by the Baathist government of Iraq. Many Assyrians arrived during this period and took advantage of the ongoing White flight in Detroit.
