Kingsblood Royal by Sinclair Lewis

Kingsblood Royal is a forgotten masterpiece by the first American to win the Nobel Prize for literature, Sinclair Lewis (who also won the Pulitzer, but remains the only author ever to decline it).

"Kingsblood Royal" was extremely controversial for its time and involves a middle aged American banker who discovers in 1940's America that he is part black. Because of the times this led to massive controversy, and was an explicit confrontation of race and race relations in the United States.

This book was popular at the time it was published, and then the powers that be quickly saw that it fell to the wayside out of print, and in fact this book was not re-printed until very recently.

The main character, Neil Kingsblood, physically resembles Walter White, the famous leader of the National Association for the Advancement of Colored People (NAACP) during that era, a detail often lost on modern audiences, but that was not lost at the time.

Neil Kingsblood discovers he has a smidgen of West African ancestry through a black ancestor while researching his family's genealogy, in hope of supporting his father's belief the Kingbloods are the real heirs to the British throne.

To Neil's extreme surprise, Xavier Pic is everything a person would want in an ancestor: very intelligent, resourceful, and brave . . . but he is also an African man, which had huge consequences in that era of American society.

Kingsblood is not the kind of person who can make a discovery of this magnitude and then just walk away. He feels compelled to act on it. So, he begins a series of acts that will result in the white friends and family ostracizing him as he tries to do what he sees as right, the first step of which is to openly claim his black ancestry.

Neil "lost everything," at least by the standards of white middle class American society. Money, home, stature, family...but it's undeniable that he undergoes a great change and goes from being "a plain white man," to a real person.

Neil learns to judge others for who they are, learns to accurately see through politics to probe deeply into controversial topics and analyze them accurately while finding an inner strength that is undeniable to all who know him.
