through limiting immigration from Eastern Europe and Southern Europe, as well as the complete end of immigration from East Asia. He also advocated efforts to purify the American population through selective breeding. He served as the vice president of the Immigration Restriction League from 1922 to his death. Acting as an expert on world racial data, Grant also provided statistics for the Immigration Act of 1924 to set the quotas on immigrants from certain European countries. Even after passing the statute, Grant continued to be irked that even a smattering of non-Nordics were allowed to immigrate to the country each year. He also assisted in the passing and prosecution of several anti-miscegenation laws, including the Racial Integrity Act of 1924 in the state of Virginia, where he sought to codify his particular version of the "one-drop rule" into law. Though Grant was extremely influential in legislating his view of racial theory, he began to fall out of favor in the United States in the early 1930s. The declining interest in his work has been attributed both to the effects of the Great Depression, which resulted in a general backlash against Social Darwinism and related philosophies, and to the changing dynamics of racial issues in the United States during the interwar period. Rather than subdivide Europe into separate racial groups, the bi-racial (black vs. white) theory of Grant's protegé Lothrop Stoddard became more dominant in the aftermath of the Great Migration of African-Americans from Southern States to Northern and Western ones (Guterl 2001). Legacy According to historian of economics Thomas C. Leonard:Prominent American eugenicists, including movement leaders Charles Davenport and Madison Grant, were conservatives. They identified fitness with social and economic position, and they also were hard hereditarians, dubious of the Lamarckian inheritance clung to by progressives. But as eugenicists, these conservatives were not classical liberals. Like all eugenicists, they were illiberal. Conservatives do not object to state coercion so long as it is used for what they regard as the right purposes, and these men were happy to trample on individual rights to obtain the greater good of improved hereditary health....Historians invariably style Madison Grant a conservative, because he was a blueblood clubman from a patrician family, and his best- known work, The Passing of the Great Race, is a museum piece of scientific racism. But Grant’s eugenic ideas originated from a corner of the conservative impulse intimately connected to
