Middlesbrough (/ˈmɪdəlzbrə/ MID-əlz-brə) is a town on the southern bank of the River Tees in North Yorkshire, England. It is near the North York Moors national park and the main town of its local council and borough. Until the early 1800s, the area was rural farming land. By 1830, a new industrial town and port started to be developed, driven by the coal and later ironworks. Steel production and ship building began in the late 1800s, remaining associated with the town until post-industrial decline occurred in the late twentieth century. Trade (notably through ports) and digital enterprise sectors contemporarily contribute to the local economy, Teesside University and Middlesbrough College to local education. In 1853, it became a town. The motto Erimus ("We shall be" in Latin) was adopted, it reflects Fuimus ("We have been") of the Bruce clan which were Cleveland's mediaeval lords. The town's coat of arms is three ships representing shipbuilding and maritime trade and an azure (blue) lion, the latter also from the Bruce clan. In 1889, the North Riding of Yorkshire became an administrative county, the town's municipal borough also became a county borough. From 1968 until 1974, some boroughs and parishes both from the rest of the county and County Durham formed the County Borough of Teesside. A star replaced the middle ship (from Captain James Cook's arms) in the recreated namesake borough's arms, with Cleveland becoming non-metropolitan county in 1974 which was abolished in 1996 with the borough council becoming a unitary authority in North Yorkshire. The borough had an estimated population of 140,980 in 2019, the 155th most populous district of England. At the 2011 census, the Middlesbrough subdivision of the Teesside built-up area had a population of 174,700, the population is larger due to an area outside the council area known as Greater Eston. The built-up area, of which Middlesbrough forms the largest part, had a population of 376,633.
