Dartford, United Kingdom

During the medieval period Dartford was an important waypoint for pilgrims and travellers en route to Canterbury and the Continent, and various religious orders established themselves in the area. In the 12th century the Knights Templar had possession of the manor of Dartford; the National Trust property at Sutton-at-Hone, to the south of the town, is a remaining piece of that history. In the 14th century, a priory was established here, and two groups of friars—the Dominicans and the Franciscans—built hospitals here for the care of the sick. At this time the town became a small but important market town.

Wat Tyler, a key figure in the Peasants' Revolt, may have been from Dartford, though three other towns in Kent also claim him, and there are some doubts about the strength of Tyler's connection to Dartford. It is, however, probable that Dartford was a key meeting point early in the Peasants' Revolt, with a detachment of Essex rebels marching south to join Kentish rebels at Dartford before accompanying them to Rochester and Canterbury in the first week of June 1381. Although lacking a leader, Kentishmen had assembled at Dartford around 5 June through a sense of county solidarity at the mistreatment of Robert Belling, a man claimed as a serf by Sir Simon Burley. Burley had abused his royal court connections to invoke the arrest of Belling and, despite a compromise being proposed by bailiffs in Gravesend, continued to demand the impossible £300 of silver for Belling's release. Having left for Rochester and Canterbury on 5 June, the rebels passed back through Dartford in greater numbers on 12 June on their way to London.

In the 15th century, two kings of England became part of the town's history. Henry V marched through Dartford in November 1415 with his troops after fighting the French at the Battle of Agincourt; in 1422 Henry's body was taken to Holy Trinity Church by Edmund Lacey, Bishop of Exeter, who conducted a funeral. In March 1452, Richard, Duke of York, camped at the Brent allegedly with ten thousand men, waiting for a confrontation with King Henry VI. The Duke surrendered to the king in Dartford. The place of the camp is marked today by York Road, Dartford.

The 16th century saw significant changes to the hitherto agrarian basis of the market in Dartford, as new industries began to take shape (see below). The priory was destroyed in 1538 during the Dissolution of the Monasteries and a new manor house was subsequently constructed by King Henry VIII. In 1545, Henry held a series of meetings of his Privy Council in the town, and from 21 to 25 June 1545 Dartford was the seat of the national government. Henry's fourth wife Anne of Cleves lived at the new priory for four years before her death in 1557.

Many Protestants were executed during the reigns of Queen Mary (1553–1554) and Philip and Mary (1554–1558), including Christopher Wade, a Dartford linen-weaver who was burnt at the stake on the Brent in 1555. The Martyrs' Memorial on East Hill commemorates Wade and other Kentish Martyrs. In 1576 Dartford Grammar School was founded, part of the Tudor emphasis on education for ordinary people.

The earliest industries were those connected with agriculture, such as the brewing of traditional beers and ales. Lime-burning and chalk-mining also had their place. Fulling was another: the cleansing of wool needed a great deal of water, which the river could provide. This led to other water-based industries, using hydropower to operate machinery.

Upon his return in 1578 from Frobisher Bay in the Canadian Arctic with a reputed cargo of gold-bearing ore, Sir Martin Frobisher had the refining done on Powder Mill Lane in Dartford. Assiduous efforts to extract gold were made over five years, but the ore proved to be a valueless rock containing hornblende and was eventually salvaged for road metalling and wall construction. Sir John Spielman set up the first paper mill in England at Dartford in 1588 on a site near Powder Mill Lane, and soon some 600 employees worked there, providing an invaluable source of local employment. Iron-making on the Weald was in full operation at this time, and iron ingots were sent to Dartford, to England's first iron-slitting mill, set up by the Darent at Dartford Creek in 1595 by Godfrey Box, an immigrant from the Low Countries. In 1785, John Hall, a millwright set up a workshop in Lowfield Street and began to make engines, boilers and machinery (some of it for the local gunpowder factory run by Miles Peter Andrews and the Pigou family), marking the foundation of J & E Hall, an engineering firm specialising in heavy engineering, and later refrigerating equipment, and, for 20 years from 1906, vehicle production, plus lifts and escalators.
