The peace agreement reached between Great Britain and Ireland 25 years ago marked the beginning of the end of the period of violence known as "The Troubles" in Northern Ireland.
On one side stood Catholics who wanted to see a united Ireland, on the other stood Protestants who wanted to maintain ties with Britain. More than 3,700 people were killed during the 30-year period when the fighting was at its worst.
Petrol bombs in Derry
That the 25th anniversary of the agreement stirs up emotions became clear on Monday. In the run-up to the anniversary, over 90 different parades and manifestations had been reported and approved by the local police. Others took the liberty of demonstrating without permission, whereupon violence broke out in some places.
"Our police officers have been attacked in Creggan with petrol bombs and other objects while at an unannounced Easter parade. No injuries have been reported at this time," the police department wrote on Monday afternoon.
Northern Irish police have also previously warned that armed republicans could carry out attacks on police over the Easter weekend.
"We were born into the war zone"
For many Northern Irishmen, however, the anniversary means more than an opportunity to demonstrate, it also serves as a reminder of the importance of peace.
Gleann Doherty was only seven months old when his father was killed on Bloody Sunday in 1972. He remembers how soldiers patrolled the streets and how sudden gun battles were not at all uncommon while walking to school.
"We were born into this war zone, so we didn't know anything else," he told SVT's team on site in Derry.
The wounds from "The Troubles" are hard to heal, he says, but anything is better than the violence.
"My daughter hasn't had to experience what I experienced. She has never had to see the British army on the streets.
