I. The Constituencies
Between 1790 and 1801 the House of Commons consisted of 558 Members elected by 314 constituencies. The 245 English constituencies (40 counties, 203 boroughs, 2 universities) returned 489 Members; the 24 Welsh constituencies and 45 Scottish constituencies returned one Member each. In 1801 the addition of 100 Irish Members elected by 66 constituencies made an Imperial Parliament of 658 Members.
