By using documented historical fact, Madison Grant proved that the colonial stock who opened up America for settlement were primarily of Northwestern European stock, with particular emphasis on its English and Ulster Scots roots. He goes on to show how America reached its greatest degree of racial homogeneity in 1860 and that later immigration from all parts of the world was undermining this founding stock. Grant's predictions of what would happen if unlimited immigration was allowed once again, and if the existing racial problems left by slavery and illegal Mexican immigration were not addressed, make sobering reading. Contains all the original maps and two new appendices which details how the Anti-Defamation League sought to suppress this book; and a 2006 study which showed that the number of Americans born with blue eyes had dropped from 1 in 2 in 1900 to less than 1 in 6 in 2000-proof of the accuracy of Grant's predictions that unlimited immigration would lead to the de-Nordicization of America.
