little later than some other critics. Others have proposed 1780–1830. In other fields and other countries the period denominated as Romantic can be considerably different; musical Romanticism, for example, is generally regarded as only having ceased as a major artistic force as late as 1910, but in an extreme extension the Four Last Songs of Richard Strauss are described stylistically as "Late Romantic" and were composed in 1946–48. However, in most fields the Romantic period is said to be over by about 1850, or earlier. The early period of the Romantic era was a time of war, with the French Revolution (1789–1799) followed by the Napoleonic Wars until 1815. These wars, along with the political and social turmoil that went along with them, served as the background for Romanticism. The key generation of French Romantics born between 1795 and 1805 had, in the words of one of their number, Alfred de Vigny, been "conceived between battles, attended school to the rolling of drums". According to Jacques Barzun, there were three generations of Romantic artists. The first emerged in the 1790s and 1800s, the second in the 1820s, and the third later in the century. Context and place in history The more precise characterization and specific definition of Romanticism has been the subject of debate in the fields of intellectual history and literary history throughout the 20th century, without any great measure of consensus emerging. That it was part of the Counter-Enlightenment, a reaction against the Age of Enlightenment, is generally accepted in current scholarship. Its relationship to the French Revolution, which began in 1789 in the very early stages of the period, is clearly important, but highly variable depending on geography and individual reactions. Most Romantics can be said to be broadly progressive in their views, but a considerable number always had, or developed, a wide range of conservative views, and nationalism was in many countries strongly associated with Romanticism, as discussed in detail below. In philosophy and the history of ideas, Romanticism was seen by Isaiah Berlin as disrupting for over a century the classic Western traditions of rationality and the idea of moral absolutes and agreed values, leading "to something like the melting away of the very notion of objective truth", and hence not only to nationalism, but also fascism and totalitarianism, with a gradual recovery coming only after World War II. For the Romantics, Berlin says, in
