Final answer:
Violence in Northern Ireland has declined due to factors such as government intervention, stronger law enforcement, diminished support for terrorist organizations, and improved economic conditions. The establishment of the Northern Ireland Assembly was crucial for peace, and economic growth has further stabilized the region.
Step-by-step explanation:
The decline of violence in Northern Ireland can be attributed to a variety of factors, including increased government intervention, stronger law enforcement, diminished support for terrorist organizations, and improved economic conditions. The establishment of the Northern Ireland Assembly in 1998 following a series of condemned terrorist acts was a vital step towards peace, bringing together members from both sides of the societal divide. While there have been challenges along the way, the hope for lasting peace remains, partly influenced by economic improvements and the diminishing influence of extremist groups.
Economic advancements have also played a role in reducing violence—Northern Ireland, like the Republic of Ireland, has seen benefits from the creation of the EU and advances in communication, making it more attractive for international business, all factors that contribute to a more stable and prosperous society.
