 This period saw a process of rehabilitation for Highland culture. In the 1820s, as part of the Romantic revival, tartan and the kilt were adopted by members of the social elite, not just in Scotland, but across Europe, prompted by the popularity of Macpherson's Ossian cycle and then Walter Scott's Waverley novels. However, the Highlands remained very poor and traditional. The desire to improve agriculture and profits led to the Highland Clearances, in which much of the population of the Highlands suffered forced displacement as lands were enclosed, principally so that they could be used for sheep farming. The clearances followed patterns of agricultural change throughout Britain, but were particularly notorious as a result of the late timing, the lack of legal protection for year-by-year tenants under Scots law, the abruptness of the change from the traditional clan system, and the brutality of many evictions. One result was a continuous exodus from the land — to the cities, or further afield to England, Canada, America or Australia. The population of Scotland grew steadily in the 19th century, from 1,608,000 in the census of 1801 to 2,889,000 in 1851 and 4,472,000 in 1901. Even with the development of industry there were not enough good jobs. As a result, during the period 1841 – 1931, about 2 million Scots migrated to North America and Australia, and another 750,000 Scots relocated to England.
