Belfast is the capital and largest city of Northern Ireland, standing on the banks of the River Lagan on the east coast. It is the 12th-largest city in the United Kingdom and the second-largest on the island of Ireland. It had a population of 343,542 as of 2019. Belfast suffered greatly during the violence that accompanied the partition of Ireland, and especially during the more recent conflict known as the Troubles: in the 1970s and 1980s it was one of the world's most dangerous cities, with a homicide rate around 31 per 100,000.
