Derry, United Kingdom

The town became strategically more significant during the Tudor conquest of Ireland and came under frequent attack. During O'Doherty's Rebellion in 1608 it was attacked by Sir Cahir O'Doherty, Irish chieftain of Inishowen, who burnt much of the town and killed the governor George Paulet. The soldier and statesman Sir Henry Docwra made vigorous efforts to develop the town, earning the reputation of being "the founder of Derry"; but he was accused of failing to prevent the O'Doherty attack and returned to England.

What became the City of Derry was part of the relatively new County Donegal up until 1610. In that year, the west bank of the future city was transferred by the English Crown to The Honourable The Irish Society and was combined with County Coleraine, part of County Antrim and a large portion of County Tyrone to form County Londonderry. Planters organised by London livery companies through The Honourable The Irish Society arrived in the 17th century as part of the Plantation of Ulster and rebuilt the town with high walls to defend it from Irish insurgents who opposed the plantation. The aim was to settle Ulster with a population supportive of the Crown. It was then renamed "Londonderry".

This city was the first planned city in Ireland: it was begun in 1613, with the walls being completed in 1619, at a cost of £10,757. The central diamond within a walled city with four gates was thought to be a good design for defence. The grid pattern chosen was subsequently much copied in the colonies of British North America. The charter initially defined the city as extending three Irish miles (about 6.1 km) from the centre.

The modern city preserves the 17th-century layout of four main streets radiating from a central Diamond to four gateways – Bishop's Gate, Ferryquay Gate, Shipquay Gate and Butcher's Gate. The city's oldest surviving building was also constructed at this time: the 1633 Plantation Gothic cathedral of St Columb. In the porch of the cathedral is a stone that records completion with the inscription: "If stones could speake, then London's prayse should sound, Who built this church and cittie from the grounde."

During the 1640s, the city suffered in the Wars of the Three Kingdoms, which began with the Irish Rebellion of 1641, when the Gaelic Irish insurgents made a failed attack on the city. In 1649 the city and its garrison, which supported the republican Parliament in London, were besieged by Scottish Presbyterian forces loyal to King Charles I. The Parliamentarians besieged in Derry were relieved by a strange alliance of Roundhead troops under George Monck and the Irish Catholic general Owen Roe O'Neill. These temporary allies were soon fighting each other again however, after the landing in Ireland of the New Model Army in 1649. The war in Ulster was finally brought to an end when the Parliamentarians crushed the Irish Catholic Ulster army at the Battle of Scarrifholis, near Letterkenny in nearby County Donegal, in 1650.

During the Glorious Revolution, only Derry and nearby Enniskillen had a Protestant garrison by November 1688. An army of around 1,200 men, mostly "Redshanks" (Highlanders), under Alexander MacDonnell, 3rd Earl of Antrim, was slowly organised (they set out on the week William of Orange landed in England). When they arrived on 7 December 1688 the gates were closed against them and the Siege of Derry began. In April 1689, King James came to the city and summoned it to surrender. The King was rebuffed and the siege lasted until the end of July with the arrival of a relief ship.

The city was rebuilt in the 18th century with many of its fine Georgian style houses still surviving. The city's first bridge across the River Foyle was built in 1790. During the 18th and 19th centuries, the port became an important embarkation point for Irish emigrants setting out for North America.

Also during the 19th century, it became a destination for migrants fleeing areas more severely affected by the Great Famine. One of the most notable shipping lines was the McCorkell Line operated by Wm. McCorkell & Co. Ltd. from 1778. The McCorkell's most famous ship was the Minnehaha, which was known as the "Green Yacht from Derry".

During World War I, the city contributed over 5,000 men to the British Army from both Catholic and Protestant families.

During the Irish War of Independence, the area was rocked by sectarian violence, partly prompted by the guerilla war raging between the Irish Republican Army and British forces, but also influenced by economic and social pressures. By mid-1920 there was severe sectarian rioting in the city. Many people died and in addition, many Catholics and Protestants were expelled from their homes during this communal unrest. After a week's violence, a truce was negotiated by local politicians on both unionist and republican sides. (See: The Troubles in Ulster (1920–1922)).
