The night broke open in a storm of explosions and fire. The sound of shells whizzing overhead, screeching through the night like wounded pheasants, was terrifying. When the shells exploded prematurely overhead, a rain of shrapnel fell on the men below better than when the shells exploded in the trenches...

The United States has no shortage of famous military units, from the Civil War's Iron Brigade to the 101st Airborne, but one would be hard pressed to find one that had to go through as many hardships off the field as the Tuskegee Airmen, a group of African American fighter pilots who overcame Jim Crow at home and official segregation in the military to serve their country in the final years of World War II.

In The Half Has Never Been Told, historian Edward E. Baptist reveals the alarming extent to which slavery shaped our country politically, morally, and most of all, economically. Until the Civil War, our chief form of innovation was slavery. Through forced migration and torture, slave owners extracted continual increases in efficiency from their slaves, giving the country a virtual monopoly on the production of cotton, a key raw material of the Industrial Revolution.

When George Washington was elected president, he reluctantly left behind his beloved Mount Vernon to serve in Philadelphia, the temporary seat of the nation's capital. In setting up his household, he took Tobias Lear, his celebrated secretary, and eight slaves, including Ona Judge, about which little has been written. As he grew accustomed to Northern ways, there was one change he couldn't get his arms around: Pennsylvania law required enslaved people be set free after six months of residency in the state. Washington decided to circumvent the law.

His name wasn’t Chester Nez. That was the English name he was assigned in kindergarten. And in boarding school at Fort Defiance, he was punished for speaking his native language, as the teachers sought to rid him of his culture and traditions. But discrimination didn’t stop Chester from answering the call to defend his country after Pearl Harbor, for the Navajo have always been warriors, and his upbringing on a New Mexico reservation gave him the strength to excel as a marine. This is the first and only memoir by one of the original Navajo code talkers of WWII.

World War II was raging, with thousands of American soldiers fighting overseas against the injustices brought on by Hitler. Back on the home front, the injustice of discrimination against African Americans was playing out as much on Main Street as in the military. Enlisted black men were segregated from white soldiers and regularly relegated to service duties. At Fort Benning, Georgia, First Sergeant Walter Morris’s men served as guards at The Parachute School while the white soldiers prepared to be paratroopers.

In White Trash, Nancy Isenberg upends assumptions about America's supposedly class-free society. Poor whites were central to the rise of the Republican Party in the early 19th century, and the Civil War itself was fought over class issues nearly as much as it was fought over slavery. Reconstruction pitted poor white trash against newly freed slaves, which factored in the rise of eugenics. These poor were at the heart of New Deal reforms and LBJ's Great Society; they haunt us in reality TV shows like Here Comes Honey Boo Boo and Duck Dynasty.

Despite fierce prejudice and abuse, even being beaten to within an inch of her life, Fannie Lou Hamer was a champion of civil rights from the 1950s until her death in 1977. Integral to the Freedom Summer of 1964, Ms. Hamer gave a speech at the Democratic National Convention that, despite President Johnson's interference, aired on national TV news and spurred the nation to support the Freedom Democrats.

On March 2, 1955, a slim, bespectacled teenager refused to give up her seat to a white woman on a segregated bus in Mont-gomery, Alabama. Shouting "It's my constitutional right!" as police dragged her off to jail, Claudette Colvin decided she'd had enough of the Jim Crow segregation laws that had angered and puzzled her since she was a young child.

When the Emancipation Proclamation was signed in 1863, the black community owned less than one percent of the United States' total wealth. More than 150 years later, that number has barely budged. The Color of Money pursues the persistence of this racial wealth gap by focusing on the generators of wealth in the black community: black banks. The catch-22 of black banking is that the very institutions needed to help communities escape the deep poverty caused by discrimination and segregation inevitably became victims of that same poverty.
