The constituency was created under the Redistribution of Seats Act, 1885 when the two-member Parliamentary Borough of Hackney was split into three single-member divisions. The seat, officially the Southern Division of the Parliamentary Borough of Hackney was first contested at the 1885 general election. The constituency was abolished in 1955.
Boundaries
1885 - 1918
In 1885 the constituency was defined as consisting of:
The part of the No. 5 or Hackney Ward of Hackney Parish south of the centres of Everning Road, Upper Clapton Road, and the Upper and Lower Clapton Roads.
The part of Clapton Park Ward to the south of a line drawn along the centres of Glenarm Road, Glyn Road and Redwald Road to its junction with Maclaren Street, thence across the recreation grounds in Daubeney Road to the borough boundary at a point fifty feet north of a boundary post situate at the junction of the Waterworks River with the River Lea at Lead Mill Point.
1950 - 1955
Under the Representation of the People Act 1948 the Boroughs of Hackney and Stoke Newington jointly formed two seats, the borough constituencies of Stoke Newington and Hackney North and Hackney South. Hackney South was enlarged: consisting of the Metropolitan Borough of Hackney except the five wards of Leaside, Maury, Southwold, Springfield and Stamford.
Redistribution
Following a review of constituencies by the Boundary Commission appointed under the House of Commons (Redistribution of Seats) Act 1949, parliamentary seats in the metropolitan boroughs of Bethnal Green, Hackney and Stoke Newington were redrawn. The Hackney South constituency was abolished, with most passing to a new Hackney Central borough constituency, and some parts to Bethnal Green.
In May 1922 Bottomley was convicted of fraud and imprisoned in Wormwood Scrubs. He was expelled from the Commons and a writ issued for a by-election in August.
Although elected a member of the 31st parliament, Erskine-Bolst was unable to take his seat as the House had adjourned, and did not meet again prior to dissolution.
Elections in the 1910s
In December 1918 Horatio Bottomley's bankruptcy was annulled, allowing him to stand for parliament again.
