Twenty-three people have appeared at Belfast Crown Court charged with rioting in the Ardoyne area of north Belfast on 12 July last year.
All 23 admitted riotous assembly over violence which broke out after Orangemen marched past Ardoyne shops.
About 100 police officers were injured during four hours of trouble.
Nine of those in court were juveniles, including a boy who was 12 at the time of the riot. All will be sentenced after the judge views reports on them.
Most of those appearing in court were arrested after the police examined CCTV footage of the disturbances.
