Quick Summary

The Northern Ireland Assembly is a devolved legislature located in Belfast, Northern Ireland. It is part of the United Kingdom's constitutional framework, with the British prime minister as its head of government and the monarch as head of state.12

The Assembly was established following the Good Friday Agreement in 1998, which aimed to foster political accommodation between the Protestant (unionist) and Catholic (nationalist) communities. The Assembly operates on a power-sharing basis, with both unionist and nationalist legislators participating in its governance. Legislation requires support from a proportion of both groups.23

Historically, Northern Ireland had its own parliament established by the Government of Ireland Act in 1920, but this was suspended in 1972. The current Assembly, established in 1998, has seen periods of devolved power alternating with direct rule from London, reflecting the ongoing complexities of political stability and power-sharing in the region.24
