County Borough of Leeds [SEP] Introduction
The County Borough of Leeds, and its predecessor, the Municipal Borough of Leeds, was a local government district in the West Riding of Yorkshire, England, from 1835 to 1974. Its origin was the ancient borough of Leeds, which was reformed by the Municipal Corporations Act 1835. In 1889, when West Riding County Council was formed, Leeds became a county borough outside the administrative county of the West Riding; and in 1893 the borough gained city status. The borough was extended a number of times, expanding from in 1911 to in 1961; adding in stages the former area of Roundhay, Seacroft, Shadwell and Middleton parishes and gaining other parts of adjacent districts.
