Derry City lies near the border between Northern Ireland and the Republic of Ireland . It has a majority nationalist population , and nationalists won a majority of seats in the 1920 local elections . Despite this , the Ulster Unionist Party controlled the local council , Londonderry Corporation , from 1923 onwards . The Unionists maintained their majority , firstly , by manipulating the constituency boundaries ( gerrymandering ) so that the South Ward , with a nationalist majority , returned eight councillors while the much smaller North Ward and Waterside Ward , with unionist majorities , returned twelve councillors between them ; secondly , by allowing only ratepayers to vote in local elections , rather than one man , one vote , so that a higher number of nationalists , who did not own homes , were disenfranchised ; and thirdly , by denying houses to nationalists outside the South Ward constituency . The result was that there were about 2 @,@ 000 nationalist families , and practically no unionists , on the housing waiting list , and that housing in the nationalist area was crowded and of a very poor condition . The South Ward comprised the Bogside , Brandywell , Creggan , Bishop Street and Foyle Road , and it was this area that would become Free Derry .
