**The Age of Capital: 1848–1875** is a book by Eric Hobsbawm, first published in 1975. It is the second in a trilogy of books about "the long 19th century" (coined by Hobsbawm), preceded by *The Age of Revolution: Europe 1789–1848* and followed by *The Age of Empire: 1875–1914*. A fourth book, *The Age of Extremes: The Short Twentieth Century, 1914–1991*, acts as a sequel to the trilogy.
