What happens when authorities you venerate condone something you know is wrong? What does this mean about what you’ve been venerating? No issue brings this question into starker contrast than slavery. Every major religion and philosophy condoned or approved of it, but in modern times there is nothing seen as more evil. Americans confront this crisis of authority when they erect statues of Founding Fathers who slept with their slaves. And Muslims faced it when ISIS revived sex slavery, justifying it with verses from the Quran and the practice of Muhammad.

In 1765, 11 years before composing the Declaration of Independence, Thomas Jefferson bought a Qur'an. This marked only the beginning of his lifelong interest in Islam, and he would go on to acquire numerous books on Middle Eastern languages, history, and travel, taking extensive notes on Islam as it relates to English common law. Jefferson sought to understand Islam notwithstanding his personal disdain for the faith, a sentiment prevalent among his Protestant contemporaries in England and America.

In this magnificent biography, the Pulitzer Prize–winning author of American Lion and Franklin and Winston brings vividly to life an extraordinary man and his remarkable times. Thomas Jefferson: The Art of Power gives us Jefferson the politician and president, a great and complex human being forever engaged in the wars of his era.

From New York Times best-selling author and Founding Fathers' biographer Harlow Giles Unger comes the astonishing biography of the man whose pen set America ablaze, inspiring its revolution, and whose ideas about reason and religion continue to try men's souls.

As a young man, Frederick Douglass (1818-1895) escaped from slavery in Baltimore, Maryland. He was fortunate to have been taught to read by his slave owner mistress, and he would go on to become one of the major literary figures of his time. He wrote three versions of his autobiography over the course of his lifetime and published his own newspaper. His very existence gave the lie to slave owners: with dignity and great intelligence, he bore witness to the brutality of slavery.

Many other mainline Christians viewed the Quakers as a dangerous sect, so much so that they pressured the British Parliament to pass the Quaker Act of 1662. This act set forth in law the “prescribed form” of prayer and worship as designated by the state. It was a formula that specifically left the traditions of the Quakers out. Unable to gain acceptance in England, the Quakers would soon leave the place of their origin altogether and try their luck in a brave new world on another continent.

A deeply private man, shut off even to those who worked closely with him, Abraham Lincoln often captured “his best thoughts", as he called them, in short notes to himself. He would work out his personal stances on the biggest issues of the day, never expecting anyone to see these pieces of writing, which he’d then keep close at hand, in desk drawers and even in his top hat. The profound importance of these notes has been overlooked, because the originals are scattered across several different archives and have never before been brought together and examined as a coherent whole.

A forgotten, dark chapter of American history with implications for the current day, The Guarded Gate tells the story of the scientists who argued that certain nationalities were inherently inferior, providing the intellectual justification for the harshest immigration law in American history. Brandished by the upper-class Bostonians and New Yorkers - many of them progressives - who led the anti-immigration movement, the eugenic arguments helped keep hundreds of thousands of Jews, Italians, and other unwanted groups out of the US for more than 40 years.

The Catalogue of Shipwrecked Books tells the story of the first and greatest visionary of the print age, a man who saw how the explosive expansion of knowledge and information generated by the advent of the printing press would entirely change the landscape of thought and society. He also happened to be Christopher Columbus’ illegitimate son.

Central to America's idea of itself is the character of Benjamin Franklin. We all know him, or think we do: In recent works and in our inherited conventional wisdom, he remains fixed in place as a genial polymath and self-improver who was so very American that he is known by us all as the first American.

With élan and erudition - and with winning enthusiasm - Henry Louis Gates Jr. gives us a corrective yet loving homage to Rogers' work. Relying on the latest scholarship, Gates leads us on a romp through African, diasporic, and African American history in question-and-answer format. Among the 100 questions: Who were Africa's first ambassadors to Europe? Who was the first black president in North America? Did Lincoln really free the slaves? Who was history's wealthiest person? What percentage of white Americans have recent African ancestry?

Washington’s End begins where most biographies of George Washington leave off, with the first president exiting office after eight years and entering what would become the most bewildering stage of his life. Embittered by partisan criticism and eager to return to his farm, Washington assumed a role for which there was no precedent at a time when the kings across the ocean yielded their crowns only upon losing their heads. In a different sense, Washington would lose his head, too.

Ronald Reagan is hailed today for a presidency that restored optimism to America, engendered years of economic prosperity, and helped bring about the fall of the Soviet Union. Yet until now little attention has been paid to the role Reagan's personal spirituality played in his political career, shaping his ideas, bolstering his resolve, and ultimately compelling him to confront the brutal - and, not coincidentally, atheistic - Soviet empire.

John Quincy Adams was the last of his kind - a Puritan from the age of the Founders who despised party and compromise yet dedicated himself to politics and government. The son of John Adams, he was a brilliant ambassador and secretary of state, a frustrated president at a historic turning point in American politics, and a dedicated congressman who literally died in office - at the age of 80, in the House of Representatives, in the midst of an impassioned political debate.

New York Times best-selling author and committed constitutional conservative Senator Mike Lee reveals the little-known stories behind the founders' takedown of a tyrannical king and the forgotten document that created America.
