The Age of Revolution: Europe: 1789–1848 is a book by Eric Hobsbawm, first published in 1962. It is the first in a trilogy of books about "the long 19th century" (coined by Hobsbawm), followed by The Age of Capital: 1848–1875, and 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. (Source: )
