Constituencies
The House was elected in the same way as the British House of Commons. By the time of the Union, the shape of the House had been fixed with two members elected for each of the 32 Counties of Ireland, two members for each of 117 Boroughs, and two members for Dublin University, a total of 300 members. The number of Boroughs invited to return members had originally been small (only 55 Boroughs existed in 1603) but was doubled by the Stuart monarchs.
