The "Lords of the Congregation" was a group of Protestant nobles in Scotland during the 16th century. They emerged in response to the growing influence of the Catholic Church and sought to reform religious practices. This group played a significant role in the Scottish Reformation, advocating for the establishment of a Presbyterian church. In 1559, the Lords of the Congregation led a rebellion against the Catholic Queen Mary of Guise, which resulted in the establishment of Protestantism in Scotland. Their efforts culminated in the Scottish Parliament adopting the Confession of Faith in 1560, marking a pivotal moment in Scottish religious history.
