The Immigration Act of 1924 shaped the U.S. population over the course of the 20th century, greatly restricting immigration and ensuring that arriving immigrants were mostly from Northern and Western Europe. The century-old law was one of the most restrictive in U.S. history and helped create the framework for key provisions of the U.S. immigration system that remain in place a century later. This article analyzes the effect and legacy of the 1924 law.

Instead, it represented a dramatic break with decades of law providing protection to asylum seekers, as this article details.
