Has someone written a monograph on ethics and politics in the social Darwinist tradition?

Social Darwinism in Britannica.com has important information, and at its end it has:
"The theory was used to support laissez-faire capitalism and political conservatism. Class stratification was justified on the basis of “natural” inequalities among individuals, for the control of property was said to be a correlate of superior and inherent moral attributes such as industriousness, temperance, and frugality. Attempts to reform society through state intervention or other means would, therefore, interfere with natural processes; unrestricted competition and defense of the status quo were in accord with biological selection. The poor were the “unfit” and should not be aided; in the struggle for existence, wealth was a sign of success. At the societal level, social Darwinism was used as a philosophical rationalization for imperialist, colonialist, and racist policies, sustaining belief in Anglo-Saxon or Aryan cultural and biological superiority.
Social Darwinism declined during the 20th century as an expanded knowledge of biological, social, and cultural phenomena undermined, rather than supported, its basic tenets."
Social Darwinism has been thought to have a profound influence upon European fascism, in European discourse which I am familiar with.
Let me make my question more precise: What is a good monograph on the ethical/political movement Social Darwinism, which also treats its impact upon the Europen fascist movements in the first half of the 19th century.
