The East End of London, usually called the East End, is the historic core of wider East London, east of the Roman and medieval walls of the City of London, and north of the River Thames.
The East End began to emerge in the Middle Ages with initially slow urban growth outside the eastern walls, which later accelerated, especially in the 19th century, to absorb pre-existing settlements. The first known written record of the East End as a distinct entity, comes from the 1720 Survey of London, which describes London as consisting of four parts: the City of London, Westminster, Southwark, and "That Part beyond the Tower". The area was notorious for its deep poverty, overcrowding and associated social problems. This led to the East End's history of intense political activism and association with some of the country's most influential social reformers. Another major theme of East End history has been migration, both inward and outward. The area had a strong pull on the rural poor from other parts of England, and attracted waves of migration from further afield, notably Huguenot refugees, who created a new extramural suburb in Spitalfields in the 17th century, Irish weavers, Ashkenazi Jews, and, in the 20th century, Sylheti Bangladeshis.
