Gilded Age (1878-1889): This time in American history was characterized by the expansion of industry and a wave of immigration. The need for more efficient transportation developed as iron and steel production skyrocketed and western resources like gold and silver, as well as lumber, surged.
As railroads transported goods from the resource-rich West to the East, railroad expansion exploded. Oil and steel were in high demand. For many businesses, including robber barons John D. Rockefeller (in oil) and Andrew Carnegie (in steel), these industries earned an enormous fortune (people who got rich through ruthless business deals). The many enormous fortunes made during this time and the quality of life this affluence supported gave rise to the appellation "Gilded Age."
