Until World War I, many cultural ideas travelled from dominant Europe to the «New World». As the United States rose to become the leading world power in the 20th century, the main direction of transatlantic exchange reversed itself. The American idea of wilderness, at first romantically and religiously charged, found its way to Europe, as linguistic and other indicators have shown since the 1980s. The idea of the modern wolf, ecologically valuable and worthy of protection, emerged in the early postwar period, primarily in North America. The association of the two was the result of a historical coincidence; together, wolf and wilderness gained importance. In the cultural sphere of Europe, the association of wolf and wilderness was largely maintained. In the political sphere, on the other hand, various changes occurred. [ABSTRACT FROM AUTHOR]
