From the first page of The Expansion and Contraction of Gaelic.
For at least 600 years, between the tenth and the sixteenth centuries, Galloway was a Gaelic speaking land. Although both the beginning and the end of Gaelic Galloway are uncertain, that Gaelic was the language of the kingdom of Galloway established by Fergus in the early eleventh century and was still the main language of the Douglas lordship of Galloway at its end in 1455 is indisputable. In addition to the Gaelic personal and place names recorded in medieval charters, the thousands of Gaelic place names which survived to be recorded by the Ordnance Survey in the 1850's bear witness to Galloway’s Gaelic past. Furthermore, despite the language shift to Scots, there is evidence of cultural continuity between the agriculture of Gaelic Galloway and the farming practice of seventeenth and early eighteenth century Galloway. Then, at the end of the eighteenth century, the process of agricultural improvement began, a process which has continued to the present. The cumulative effect of this process in the lowlands combined with afforestation in the uplands has been the erasure of Galloway’s past. The Galloway landscape known by the Galloway Levellers and the Covenanters would have still been familiar to the medieval Gaelic farmers who named the land, but none would recognise the landscape of the present.
In 1755, it is estimated that 23% of the Scottish population (concentrated in the Highlands and Islands) spoke Gaelic. In 1901 only 4.5 % were still Gaelic speakers and by 2001 the numbers had fallen to 1.2%. Concern over the decline of Gaelic led to the passing of the Gaelic Language (Scotland) Act in 2005 and the establishment of the Bord na Gaidhlig in 2006. The Bord na Gaidhlig’s priority is to increase the number of Gaelic speakers. In November 2010, Dumfries and Galloway’s Community Learning and Development Service received funding of £45 000 from the Bord to support adult Gaelic learning in the region.As the number of Gaelic speakers in the region increases, interest in the region’s Gaelic history and the traces it has left in the place names of the region will also increase.
