Nationalism is a modern movement. Throughout history people have been attached to their native soil, to the traditions of their parents, and to established territorial authorities; but it was not until the end of the 18th century that nationalism began to be a generally recognized sentiment molding public and private life and one of the great, if not the greatest, single determining factors of modern history. Because of its dynamic vitality and its all-pervading character, nationalism is often thought to be very old; sometimes it is mistakenly regarded as a permanent factor in political behavior. Actually, the American and French revolutions may be regarded as its first powerful manifestations. After penetrating the new countries of Latin America it spread in the early 19th century to central Europe and from there, toward the middle of the century, to eastern and southeastern Europe. At the beginning of the 20th-century nationalism flowered in the ancient lands of Asia and Africa. Thus the 19th century has been called the age of nationalism in Europe, while the 20th century has witnessed the rise and struggle of powerful national movements throughout Asia and Africa.
