There is no question that the plantation of Ulster during the reign of James I had a profound effect on the course of British history. However, the nature of that plantation has been either misrepresented or misunderstood. In order to overcome this problem, we must address two provocative questions: (1) Were the Scots-Irish, the largest group of settlers, predominantly Celtic or non-Celtic ethnically and culturally? and (2) If they were mainly Celtic, why were they better able than non-Celts to establish viable settlements in Ulster, a predominantly Celtic area? A reexamination of the origins of the pre-1625 Scottish settlers and their methods of settlement indeed casts the problem of the Ulster Plantation in a new light.
For the last two decades, historians have begun to question the portrayal of the Scots-Irish, or Ulster Scots, as frugal, hardworking, anglicized Presbyterian Lowlanders who brought the light of civilization to a benighted Celtic backwater. For example, Nicholas Canny correctly dismisses the “myth” of Ulster's material transformation by pointing out that the province, unlike Leinster and Munster, was settled by British planters from less economically advanced areas of the archipelago. But, again, he does not adequately examine the cultural and ethnic background of the dominant Scots-Irish. Traditionally, they have been classed as “Lowland,” non-Celts rather than as “Highland,” Celtic Scots. These designations are misleading because they oversimplify Scotland's historical and cultural divisions that had been in place as early as the Norman invasion.
