Arbroath or Aberbrothock (Scottish Gaelic: Obair Bhrothaig) is a former royal burgh and the largest town in the council area of Angus in Scotland, and has a population of 22,785. It lies on the North Sea coast, around 16 miles (25.7 km) ENE of Dundee and 45 miles (72.4 km) SSW of Aberdeen.
While there is evidence for settlement of the area now occupied by the town that dates back to the Iron Age, Arbroath's history as a town begins in the High Middle Ages with the founding of Arbroath Abbey. Arbroath grew considerably during the Industrial Revolution owing to the expansion of the jute industry. A new harbour was built in 1839 and by the 1900s, Arbroath had become one of the larger fishing ports in Scotland. The town is notable as the home of the Declaration of Arbroath, as well as the Arbroath Smokie.
The earliest recorded name for the town was 'Aberbrothock', a reference to the Brothock Burn which runs through the town, the prefix 'Aber' coming either from the Gaelic 'Obair', or the earlier Brythonic Pictish 'Aber' for 'river mouth'. The name 'Aberbrothock' can be found in numerous spelling variations. In the earliest manuscripts available, it is seen as 'Abirbrothoke' (in the letter to Edward I confirming the Treaty of Salisbury, which agreed that the Queen regnant, Margaret, Maid of Norway would marry Edward I). In the Declaration of Arbroath, it is seen as 'Abirbrothoc'. Early maps show a number of variants including Aberbrothock, Aberbrothik, Aberbrothick, and Aberbrothwick.
