The population of NorthernIreland was estimated as being 1,710,300 on 30 June 2004.
NorthernIreland was covered by an ice sheet for most of the last ice age and on numerous previous occasions, the legacy of which can be seen in the extensive coverage of drumlins in Counties Fermanagh, Armagh, Antrim and particularly Down.
The centrepiece of NorthernIreland's geography is Lough Neagh, at 151 square miles (392 km²) the largest freshwater lake both on the island of Ireland and in the British Isles, and the third largest lake in Western Europe.
The Parliament of NorthernIreland was bicameral, consisting of a House of Commons with 52 seats, and an indirectly-elected Senate with 26 seats.
The 1921generalelection was explicitly fought on the issue of partition, being in effect a referendum on approval of the concept of a NorthernIreland administration.
The 1938 generalelection was called when the Prime Minister of the United Kingdom Neville Chamberlain was negotiating a settlement of outstanding disputes with Éamon de Valera, whose new constitution laid claim to NorthernIreland, and the 1949 election was called when the Irish government declared itself a republic.
