Scottish poetry is often seen as entering a period of decline in the nineteenth century, with a descent of into infantalism as exemplified by the highly popular Whistle Binkie anthologies (1830–90). However, Scotland continued to produce talented and successful poets, including weaver-poet William Thom (1799–1848), Lady Margaret Maclean Clephane Compton Northampton (d. 1830), William Edmondstoune Aytoun (1813–65) and Thomas Campbell (1777–1844), whose works were extensively reprinted in the period 1800–60. Among the most influential poets of the later nineteenth century were James Thomson (1834–82) and John Davidson (1857–1909), whose work would have a major impact on modernist poets including Hugh MacDiarmid, Wallace Stevens and T. S. Eliot. The Highland Clearances and widespread emigration significantly weakened Gaelic language and culture and had a profound impact on the nature of Gaelic poetry. The best poetry in this vein contained a strong element of protest, including Uilleam Mac Dhun Lèibhe's (William Livingstone, 1808–70) protest against the Islay and Seonaidh Phàdraig Iarsiadair's (John Smith, 1848–81) condemnation of those responsible for the clearances. The best known Gaelic poet of the era was Màiri Mhòr nan Óran (Mary MacPherson, 1821–98), whose evocation of place and mood has made her among the most enduring Gaelic poets.
