Context: Leeds is a city in West Yorkshire, England. Historically in Yorkshire's West Riding, the history of Leeds can be traced to the 5th century, when the name referred to a wooded area of the Kingdom of Elmet. The name has been applied to many administrative entities over the centuries. It changed from being the name of a small manorial borough in the 13th century, through several incarnations, to being the name attached to the present metropolitan borough. In the 17th and 18th centuries Leeds became a major centre for the production and trading of wool. 

During the Industrial Revolution, Leeds developed into a major mill town; wool was the dominant industry but flax, engineering, iron foundries, printing, and other industries were important. From being a compact market town in the valley of the River Aire in the 16th century Leeds expanded and absorbed the surrounding villages to become a populous urban centre by the mid-20th century. Leeds has a population of around 781,700 (2016) making it the third largest city in the United Kingdom. The city lies within the United Kingdom's fourth-most populous urban area, with a population of 2.3 million. 

Today, Leeds has the most diverse economy of all the UK's main employment centres and has seen the fastest rate of private-sector jobs growth of any UK city and has the highest ratio of public to private sector jobs of all the UK's Core Cities. Leeds has the third-largest jobs total by local authority area with 480,000 in employment and self-employment at the beginning of 2015. Leeds is also ranked as a gamma world city by the Globalization and World Cities Research Network; and is considered the cultural, financial and commercial heart of the West Yorkshire Urban Area. Leeds is served by four universities, and has the fourth largest student population in the country and has the country's fourth largest urban economy.
