Kirkintilloch, United Kingdom

The castle was of some importance during the wars of independence when an English garrison was stationed there, commanded by Sir Philip de Moubray, who was later to command Stirling Castle at the time of the Battle of Bannockburn. Soldiers from the castle were dispatched to arrest William Wallace at Robroyston in 1305 and escorted him to Dumbarton Castle. Later the same year, the garrison is recorded as having sent a petition to King Edward of England complaining of non-payment of wages. The castle was attacked by Scottish forces in 1306 under Bishop Wishart of Glasgow (using timber given to Glasgow diocese by the English for cathedral repairs), but the siege was unsuccessful. The castle is thought to have been destroyed on the orders of Robert Bruce later in the conflict, although the traces of a mot surrounded by a ditch can still be seen in the Peel Park.

The original Cumming parish church, St Ninian's, was constructed around 1140 some distance to the east of the town (where some of the stones remain in the form of an 18th-century watchtower at the entrance to the Auld Aisle Cemetery) as Kirkintilloch was originally in the parish of Lenzie which stretched from Cumbernauld in the East to Kirkintilloch in the West. The establishment was part of the endowment of Cambuskenneth Abbey, and was accompanied by a grant of one oxgang of land (approximately 15 acres), the measurement that lent its name to the area near the church. A chapel to the Virgin Mary was established in the town itself, sometime before 1379, and was endowed with land at Duntiblae by Sir David Fleming. The move of the parish church to the site of the chapel at Kirkintilloch Cross (now the Auld Kirk Museum) in 1644 resulted in a split of the Parish into Easter and Wester Lenzie (later Cumbernauld and Kirkintilloch Parishes) The name Lenzie was later reused for Kirkintilloch's railway station on the main Glasgow to Edinburgh line, around which the later village of that name developed.

Following the Scottish victory in the wars of independence and the subsequent decline of Clan Cumming, the baronies of Kirkintilloch, Lenzie, and Cumbernauld were granted by Robert Bruce to Sir Malcolm Fleming, sheriff of Dumbarton and a supporter of the Bruce faction in the war. Hitherto part of Stirlingshire, the area subsequently became a detached part of the county of Dumbarton, in which it remains today.

On 3 January 1746, the retreating Jacobite army of Charles Stuart made its way through Kirkintilloch, on its way back from Derby, and on the march to Falkirk and ultimately Culloden. One of the Highland army's stragglers was shot dead at the town cross by a man hidden in a barn at the Kiln Close (where the library now stands). On hearing of the murder, Charles halted his army on the Kilsyth road and threatened to turn back and burn the town. The town magistrates persuaded him to continue marching, in return for an unspecified payment, and the town was spared.

The town was one of the hotbeds of the Industrial Revolution in Scotland, beginning with the emergence of a booming textile industry in the area. There were 185 weavers in Kirkintilloch by 1790, and in 1867 James Slimon's cotton mill at Kelvinside employed 200 women. With the construction of the Forth and Clyde Canal through the town in 1773, and the establishment of the Monkland and Kirkintilloch Railway in 1826, Kirkintilloch developed further as an important transportation hub, inland port and production centre for iron, coal, nickel and even small ships. This industrial heritage lives on in the town's designation as the "Canal Capital of Scotland", and in the redevelopment of the canal and surrounding former industrial sites in the early 21st century.

By the 20th century, the principal employers in the town were the shipbuilders J & J Hay and Peter McGregor, and the Lion (1880–1984) and Star foundries, all of which produced goods for the domestic market and for export around the world. Kirkintilloch's most famous exports were the distinctive red British post boxes and phone boxes K2 to K6, produced in the town until 1984.

In the 1930s Kirkintilloch was a location for Irish seasonal workers; it has been estimated that a quarter of the inhabitants were then of Irish descent. On 15 September 1937 ten young migrant potato pickers from Achill in Ireland died in a fire at Kirkintilloch.

Kirkintilloch was a "dry town" for much of its recent history, with the sale of alcohol on public premises banned from 1923 until 1967. The prohibition on the sale of alcohol had long been demanded by the Liberal Party and the temperance movement, both of which had a strong influence in the town in the early part of the 20th century, largely due to the perceived negative effects of alcohol on the town's inhabitants.
