What is the importance of the "Raj" as noted in the nonfiction book, White?

The Raj is the rule of the British Crown in India during colonial times, and is represented in this book as a symbol of white impotence and destruction. By discussing the Raj at length in the chapter titled, "There's Nothing I Can Do! Nothing!" Dyer acknowledges the construction of whiteness as both enterprising and imperialistic, having built the Raj through violence and other means, as well as destructive and impotent, since the British consequently lost the Raj and faced humiliating uprising by Indian citizens. Dyer writes that the arrival of white women complicated the racial dynamics between white males and the native population, specifically native women and prostitutes, thus contributing to the fall of the Raj and the loss of white male prestige on the subcontinent.
