Why is "Scottish religion in the nineteenth century" trending?

Wikipedia Overview

Scottish religion in the nineteenth century includes all forms of religious organisation and belief in Scotland in the 19th century. This period saw a reaction to the population growth and urbanisation of the Industrial Revolution that had undermined traditional parochial structures and religious loyalties. The established Church of Scotland reacted with a programme of church building from the 1820s. Beginning in 1834 the "Ten Years' Conflict" ended in a schism from the established Church of Scotland led by Dr Thomas Chalmers known as the Great Disruption of 1843. Roughly a third of the clergy, mainly from the North and Highlands, formed the separate Free Church of Scotland. The evangelical Free Church and other secessionist churches grew rapidly in the Highlands and Islands and urban centres. There were further schisms and divisions, particularly between those who attempted to maintain the principles of Calvinism and those that took a more personal and flexible view of salvation. However, there were also mergers that cumulated in the creation of a United Free Church in 1900 that incorporated most of the secessionist churches.
