After the 1918 election, Sinn Féin invited all those
elected for constituencies in Ireland to sit as
TDs in
Dáil Éireann rather than in the House of Commons of the United Kingdom. All those elected for Irish constituencies were included in the roll of the Dáil but only those elected for Sinn Féin sat in the
First Dáil. In May 1921, the Dáil passed a resolution declaring that
elections to the House of Commons of Northern Ireland and the House of Commons of Southern Ireland would be used as the election for the
Second Dáil and that the First Dáil would be dissolved on the assembly of the new body. The area of Belfast Duncairn would then have been represented in the Dáil by the four-seat constituency of
Belfast North, which also returned no representatives for Sinn Féin. ==Members of Parliament==
