Belfast ( BEL-fast, , -fahst; from Irish: Béal Feirste [bʲeːlˠ ˈfʲɛɾˠ(ə)ʃtʲə]) is the capital city and main port of Northern Ireland, standing on the banks of the River Lagan and connected to the open sea through Belfast Lough and the North Channel. It is the largest city in Northern Ireland and the second-largest city in Ireland (after Dublin) with a recorded population in 2021 of 345,418 and of 704,406 for the greater metropolitan area.
While chartered as an English settlement in 1613, the town's early growth was driven by an influx of Scottish Presbyterians. Their descendants' disaffection with Ireland's Anglican establishment contributed to the rebellion of 1798 and to the 1801 union with Great Britain that followed. Access to British capital and markets was transformative. When granted city status in 1888, Belfast was the world's largest centre of linen manufacture, and by the 1900s its shipyards were building up to a quarter of all United Kingdom tonnage.
New industry, which drew large numbers of Catholics from rural districts, was accompanied by growing sectarian tensions in what had been a largely Protestant town. Heightened by division over Ireland's future in the United Kingdom, these twice erupted in periods of sustained violence involving paramilitaries and security forces: in 1920–22, as Belfast became the capital of the six northeastern counties retaining the British connection, and in the so-called Troubles, the three decades from the late 1960s during which the British Army was continually deployed on the streets. A legacy of conflict is the barrier-reinforced separation of Protestant and Catholic working-class districts. Since the Good Friday Agreement, the electoral balance in the once Unionist-controlled city has shifted, albeit with no overall majority, in favour of Irish nationalists. New immigrants are adding to the growing number of residents unwilling to identify with either of the two communal traditions.
Belfast has seen significant services sector growth, with important contributions from financial technology (fintech), tourism and, with facilities in the redeveloped Harbour Estate, film. It retains a port with commercial and industrial docks, including a reduced Harland & Wolff shipyard and aerospace and defence contractors. Under the Windsor Framework, Belfast and Northern Ireland effectively remain, post Brexit, within both the British domestic, and European Single Market, trading areas for goods.
The city is served by two airports: Belfast City Airport, located on the Lough shore, and Belfast International Airport (also known as Aldergrove), located 15 miles (24 kilometres) west of the city. Belfast supports two universities: Ulster University in the city centre, and in the Botanic area in the south of the city, Queen's University Belfast. Since 2021, Belfast has been a UNESCO designated City of Music.
The name Belfast derives from the Irish Béal Feirste (Irish pronunciation: [bʲeːlˠ ˈfʲɛɾˠ(ə)ʃtʲə]), "Mouth of the Farset", a river whose name comes from Irish fearsaid, meaning a sandbar or tidal ford. This was formed where the Farset flowed into the Lagan, along what is now High Street, until culverted in the late 18th century. It was at this crossing, under or near the current Queen's Bridge, that the early settlement developed.
The compilers of Ulster-Scots use various transcriptions of local pronunciations of "Belfast" (with which they sometimes are also content) including Bilfawst, Bilfaust or Baelfawst.
As a legacy of emigration, Belfast has lent its name to more than a dozen settlements in the United States, of which the largest is Belfast, Maine, and to one each in Australia, Canada, New Zealand and South Africa.
The site of Belfast has been occupied since the Bronze Age. The Giant's Ring, a 5,000-year-old henge, is located near the city, and the remains of Iron Age hill forts can still be seen in the surrounding hills. At the beginning of the 14th century, Papal tax rolls record two churches: the "Chapel of Dundela" at Knock (Irish: cnoc, meaning "hill") in the east, connected by some accounts to the 7th-century evangelist St. Colmcille,and, the "Chapel of the Ford", which may have been a successor to a much older parish church on the present Shankill (Seanchill, "Old Church") Road, dating back to the 9th, and possibly to St. Patrick in the mid 5th, century.
In the late 12th century, the Normans established a settlement at the ford comprising a parish church (now St. George's), a watermill and a fort . It was repeatedly taken, demolished, and rebuilt until, at the end of the 16th century, the scorched- earth Nine Years' War broke the remaining Irish power, the O'Neills.
Developing port, radical politics
With a commission from King James VI, in 1613 Sir Arthur Chichester undertook the Plantation of Belfast and the surrounding area, building a new castle in what is now Castle Place, and attracting mainly English and Manx settlers. The subsequent arrival of Scottish Presbyterians embroiled Belfast in its only recorded siege: denounced from London by John Milton as "ungrateful and treacherous guests", in 1649 the newcomers were temporarily expelled by an English Parliamentarian army. In 1689, Catholic Jacobite forces, briefly in command of the town, abandoned it in advance of the landing at Carrickfergus of William, Prince of Orange, who proceeded through Belfast to his celebrated victory on 12 July 1690 at the Boyne.
Together with French Huguenots, the Scots introduced the production of linen, a flax-spinning industry that in the 18th century carried Belfast trade to the Americas. Fortunes were made carrying rough linen clothing and salted provisions to the slave plantations of the West Indies; sugar and rum to Baltimore and New York City; and for the return to Belfast flaxseed and tobacco from the colonies. From the 1760s, profits from the trade financed improvements in the town's commercial infrastructure, including the Lagan Canal, new docks and quays, and the construction of the White Linen Hall which together attracted to Belfast the linen trade that had formerly gone through Dublin. Abolitionist sentiment, however, defeated the proposal of the greatest of the merchant houses, Cunningham and Greg, in 1786 to commission ships for the Middle Passage.As "Dissenters" from the established Anglican church (with its episcopacy and ritual), Presbyterians were conscious of sharing, if only in part, the disabilities of Ireland's dispossessed Roman Catholic majority; and of being denied representation in the Irish Parliament. Belfast's two MPs remained nominees of the Chichesters (Marquesses of Donegall). With their emigrant kinsmen in America, the region's Presbyterians were to share a growing disaffection from the Crown.
When early in the American War of Independence, Belfast Lough was raided by the privateer John Paul Jones, the townspeople assembled their own Volunteer militia. Formed ostensibly for defence of the Kingdom, Volunteer corps were soon pressing their own protest against "taxation without representation". Further emboldened by the French Revolution, a more radical element in the town, the Society of United Irishmen, called for Catholic emancipation and a representative national government. In hopes of French assistance, in 1798 the Society organised a republican insurrection. The rebel tradesmen and tenant farmers were defeated north of the town at the Battle of Antrim and to the south at the Battle of Ballynahinch.
Britain seized on the rebellion to abolish the Irish Parliament, unlamented in Belfast, and to incorporate Ireland in a United Kingdom. In 1832, British parliamentary reform permitted the town its first electoral contest – an occasion for an early and lethal sectarian riot.
Industrial expansion, sectarian division
While other Irish towns experienced a loss of manufacturing, from the 1820s Belfast underwent rapid industrial expansion. After a cotton boom and bust, the town emerged as the global leader in the production of linen goods (mill, and finishing, work largely employing women and children), winning the moniker "Linenopolis". Shipbuilding led the development of heavier industry. By the 1900s, her shipyards were building up to a quarter of the total United Kingdom tonnage, and on the eve of the First World War, in 1914, close one eighth of world production. This included from the yard of Harland & Wolff the ill-fated RMS Titanic, at the time of her launch in 1911 the largest ship afloat. Other major export industries included textile machinery, rope-making, tobacco and mineral waters.
