Why is violence flaring up between Ajax and Hajduk supporters?

Violent confrontations have erupted in Split between hundreds of Hajduk Split supporters and Ajax fans ahead of their scheduled match. Croatian authorities intervened to prevent serious injuries, arresting 57 individuals following a clash between 300 Hajduk supporters and 200 Ajax fans. Local police had increased surveillance and security measures in anticipation of such violence, while Ajax leadership had explicitly warned their supporters about the risks involved in traveling to Croatia for this game. Journalists suggest the aggression stems from the reputation of Hajduk Split's hard-core fan group, known as Torcida, which has become increasingly violent over the decades. The hostility appears motivated by the desire of the local group to challenge the reputation of Ajax's own supporters. In response to the ongoing unrest, authorities have mandated that visiting fans use designated transport points to reach the stadium safely. Ajax has consistently advised fans to avoid the city center and adhere strictly to official safety protocols provided by the club and the UEFA.
