the wall on the north side, which discouraged development in that direction. Urbanisation accelerated in the 16th century and the area that would later become known as the East End began to take shape. Growth Until about 1700, London did not extend far beyond the walled boundaries of the City of London. However, the population in the parishes to the east of the City of London was rising and this led to a need to break up the large ancient parish of Stepney into smaller units to provide adequate religious and civil administration. It was the industries associated with the River Thames, such as shipbuilding and the docks, that encouraged growth in the east, and by 1650, Shadwell was a developed maritime settlement. The docks in Tower Hamlets started to reach capacity in the early 19th century, and in 1855 the Royal Victoria Dock was opened in Newham. By 1882, Walter Besant and others, were able to describe East London as a city in its own right, on account of its large size and social disengagement from the rest of London. Railway expansion The majority of the rail network in East London was built within fifty years from 1839. The first through the area was the Eastern Counties Railway from Mile End to Romford, extended to Shoreditch in 1840. The London and Blackwall Railway built a line from Minories to Blackwall the same year and the Northern and Eastern Railway connected Lea Bridge and Tottenham with the Eastern Counties at Stratford. The Eastern Counties and Thames Junction Railway started passenger service on their line from Stratford to Canning Town, Custom House and North Woolwich in 1847. This made Stratford a significant railway junction and location of railway works. The East & West India Docks & Birmingham Junction Railway connected Kingsland with Bow and Poplar in 1850 and was renamed North London Railway in 1853. In 1854 the London, Tilbury and Southend Railway connected Forest Gate on the Eastern Counties with Barking and Rainham. The East London Railway was opened in 1869. The Great Eastern Railway connected Lea Bridge with Walthamstow in 1870, and in 1872 built a connection from the Eastern Counties line at Bethnal Green to Hackney Downs. This was connected to the Walthamstow line in 1873 and extended to Chingford. The London and Blackwall built an extension to Millwall and North Greenwich on the Isle of Dogs in
