The Troubles (Irish: Na Trioblóidí) were an ethno-nationalist[15][16][17][18] conflict in Northern Ireland that lasted about 30 years from the late 1960s to 1998.[19] Also known internationally as the Northern Ireland conflict,[20][21][22][23] it is sometimes described as an "irregular war"[24][25][26] or "low-level war".[27][28][29] The conflict began in the late 1960s and is usually deemed to have ended with the Good Friday Agreement of 1998.[4][5][30][31][32] Although the Troubles mostly took place in Northern Ireland, at times violence spilled over into parts of the Republic of Ireland, England and mainland Europe.
