In United States history, Gilded Age refers to the period following the Civil War and Reconstruction, running from the late 1860s to 1896.

The term "Gilded Age" was coined by Mark Twain and Charles Dudley Warner in their book The Gilded Age: A Tale of Today (1873). The term refers to the gilding of a cheaper metal with a thin layer of gold, with a hint of the "golden age" of a nation's glory. Many critics at the time complained that the era was marked by ostentatious display, crass manners, political corruption, and shoddy ethics.

Historians point out that it was a time of enormous industrial, urban and agricultural growth, that attracted millions of eager workers from Europe. Railroads were the major industry, but the factory system and mining were important as well, and labor unions began to be important. The growth was interrupted by major nationwide depressions known as the Panic of 1873 and the Panic of 1893. Much of the growth, however, only applied to the former Union states. The former confederacy was still economically devastated from the Civil War and their economy became increasingly tied to cotton and tobacco production. Black Americans in the south experienced the worst setbacks, as they were stripped of political power and voting rights. The political landscape was unique in that despite rampant corruption turnout was high and elections between the evenly matched parties were close. The dominant issues were rights for Black Americans, tariff policy and monetary policy. Reformers worked for civil service reform, prohibition and woman suffrage, while philanthropists built colleges and hospitals, and the many religious denominations exerted a major sway in everyday life.

Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), better known by his pen name Mark Twain, was an American author and humorist. He is most noted for his novels, The Adventures of Tom Sawyer (1876), and its sequel, Adventures of Huckleberry Finn (1885), the latter often called "the Great American Novel."

Twain grew up in Hannibal, Missouri, which would later provide the setting for Huckleberry Finn and Tom Sawyer. He apprenticed with a printer. He also worked as a typesetter and contributed articles to his older brother Orion's newspaper. After toiling as a printer in various cities, he became a master riverboat pilot on the Mississippi River, before heading west to join Orion. He was a failure at gold mining, so he next turned to journalism. While a reporter, he wrote a humorous story, "The Celebrated Jumping Frog of Calaveras County", which became very popular and brought nationwide attention. His travelogues were also well-received. Twain had found his calling.

He achieved great success as a writer and public speaker. His wit and satire earned praise from critics and peers, and he was a friend to presidents, artists, industrialists, and European royalty.

Richard Norton Smith (born 1953) is an American historian and author specializing in US presidents.

Born in Leominster, Massachusetts, in 1953, Smith graduated magna cum laude from Harvard University in 1975 with a degree in government. Following graduation he worked as a White House intern and as a free-lance writer for The Washington Post. He became a speech writer for Massachusetts Senator Edward Brooke, and then Senator Bob Dole, with whom he has collaborated on numerous projects over the years.

Smith’s first major book, Thomas E. Dewey and His Times, was a finalist for the 1983 Pulitzer Prize. He has also written An Uncommon Man: The Triumph of Herbert Hoover (1984), The Harvard Century: The Making of a University to a Nation (1986) and Patriarch: George Washington and the New American Nation (1993). In June 1997, Houghton Mifflin published his biography of Robert R. McCormick The Colonel: The Life and Legend of Robert R. McCormick, which was later reprinted by Northwestern University Press in 2003. It received the Goldsmith Book Prize awarded by Harvard University’s John F. Kennedy School of Government in 1998. Historian David M. Kennedy called it a "candid and colorful biography".
