This theses centres around the concept that there were sectarian elements present in job adverts in newspapers during 1820s and 1830s. The work is broken down into three chapters. Chapter one deals with the background to the specified period from 1798 to 1820. The purpose in including this research has been in laying the groundwork for events that occurred during the 1820s and 1830s. Elements that helped to create religious tensions during our period had their roots in the early 1800s; therefore, it has been necessary to include them within the body of work. Chapter Two deals with the political and religious changes occurring during the two decades under consideration. this involved examining the actions of both the Catholic and Protestant bodies and their responses to changed in the political and religious atmosphere. These changed revolved around such things as the campaign for Catholic emancipation, or the repeal of the union. There was also the revival of widespread religious belief centring on the actions of evangelical missionaries and the belief in prophetic messages foretelling the coming of the apocalypse. These issues influenced the lower classes making them adhere to one another based on religious beliefs. There was widespread sectarianism in Ireland during this period but the purpose of this theses has been to illustrate how sectarianism manifested itself into elements of everyday life. It is in chapter three that the five newspapers under consideration are studied for the presence of sectarian job adverts. Over the course of the research, it became apparent that the use of sectarianism in job adverts was a Protestant reaction carried out mainly because of the panic they had begun to feel over the rapid changes that occurring in their lifestyles. As the minority group, Protestants were more likely to feel the need to come together for a sense of security within the community and the job adverts with the sectarian overtones was simply another avenue for them to gain that security.
