It’s the 21st of November and you are at the home stadium of Real Madrid for the el clasico. Fans cheer and sing the club anthem in this sense of pride and commitment to their respective teams. You begin to feel this surge of patriotism and worth of your very existence at this moment; what could possibly go wrong? A rampage of opposing fans? Projected Molotov cocktails? A potential black-eye? As crazy as it may sound, those were the potential outcomes of what was usually expected during the 1950s at a casual game of football, not by the fans, but by the infamous football hooligans, who are by far and large known as, ‘overzealous supporters’ (Wikipedia). The reasons for such shocking trial of events were mainly due to racism, sense of Identity with the team and, as petty as this may sound; issues with ticketing.
Racism, being the ugly mark of human society, is still prevalent in this modern age. It doesn’t necessarily have to involve an occasional Rosa being forced to the back of the bus; but more of verbal slurs which lead to public display of violence. On the 12th of October, 2015, The Notorious fans of Israel’s Beitar Jerusalem football club are well known for shouting anti-arab slogans and throwing stones at Palastanian fans. Although there have been laws implemented to protect Palestanian fans and Arab players, atleast 25 Palestenian had been killed by the Israeli forces. As mentioned earlier, verbal offence towards a specific ethnicity especially when clubs are involved lead to major breakouts. Although Racism has reached its death, it still somehow thrives within the world of sports and has its dominance in Football. These breakouts can be stopped if the laws enforced against racism were executed well; judicially.
Many football fanatics associate themselves to a specific team or club as a sense of identity; so much that they end up getting the club logo tattooed for eternity onto their skin. These “fans” are usually the ones to stay away from. They take their club pride seriously, so much that *eg* In any case, these are the guys who end up stagnating the overall revenue. Fans fear for the worst when they have to sit in the same stadium as these pious worshippers.
And finally the shocking issue: ticketing sales. As unusual as it may seem, the rig in the ticketing sales unleashed a wave of rage-fueled hooligans who ended up destroying the name of the Turkish Football team.

Bpl hooliganism
United Kingdom[edit]
Main article: Football hooliganism in the United Kingdom
There are records of football hooliganism in the UK from the 1880s, and from no later than the 1960s the UK had a worldwide reputation for it – the phenomenon was often dubbed the English Disease.[126][127][128][129] From the 1970s, many organised hooligan firms sprang up. As a result of the Heysel Stadium disaster of 1985, where 39 Juventus fans were killed by Liverpool hooliganism, English clubs were banned from all European competitions until 1990, with Liverpool banned for an additional year.[130] According to Manchester United hooligan Colin Blaney in his autobiography 'The Undesirables', many of the football hooligan gangs in the UK used hooliganism as a cover for acquisitive forms of crime, specifically theft and burglary.[131] This has also been confirmed in numerous other articles on the subject.[132][133] In the 1980s and well into the 1990s the UK government led a major crackdown on football-related violence. While football hooliganism has been a growing concern in some other European countries in recent years, British football fans now tend to have a better reputation abroad. Although reports of British football hooliganism still surface, the instances now tend to occur at pre-arranged locations rather than at the matches themselves.
English clubs who have made the headlines for the worst and most frequent cases of hooliganism include Birmingham City (whose multi racial hooligan element gained the nickname "Zulus" from fans of rival teams in the 1970s when football hooligans were almost always white British), Chelsea (whose then chairman Ken Bates installed an electric fence at the club's stadium in the mid 1980s to combat hooligans, but was refused permission to switch it on during matches), Leeds United (who were banned from European competitions following a riot after the 1975 European Cup final against Bayern München), Liverpool (whose fans rioted at the 1985 European Cup final resulting in the death of 39 spectators at Heysel Stadium in Belgium, leading to English clubs being banned from European competitions for 5 years), Manchester United (who were booted out of the European Cup Winner's Cup in 1977 after their fans rioted a game in France, although they were reinstated to the competition on appeal), Millwall (whose most notorious hooliganism incident was in 1985 when their fans rioted in an FA Cup tie at Luton), Tottenham Hotspur (who had a section of fans banned from all football grounds in England in 2008 for their racial and homophobic abuse of former player Sol Campbell) and Wolves (who had dozens of fans convicted of incidents in the late 1980s involving the Subway Army hooligan firm at matches against teams including Cardiff City and Scarborough when they were in the Fourth Division).

TURKEYY !!!!!!

According to the Turkish Daily News, hooligan groups are well organised, have their own "leaders", and often consist of organised street fighters. These groups have a "racon" (code of conduct), which states that the intention must be to injure rather than kill and that a stab must be made below the waist.[108] Other hooligans have fired firearms into the air to celebrate their team's victory, which has been known to accidentally kill innocent people watching the celebrations on their balconies.[109][110]
Trouble has arisen during matches between Istanbul rivals Galatasaray and Fenerbahçe.[109] However, the Turkish Football Federation has tightened security to try and contain the hooliganism. During the 2005 Turkish cup final between Galatasaray andFenerbahçe, 8,000 police, stewards and officials were employed to prevent violence.[111] In 2006, the Turkish Football Federation introduced new measures to combat the threat of hooliganism and have made new regulations that allow the Professional Football Disciplinary Board to fine clubs up to YTL 250,000 for their fans behavior. Repeat offenders could be fined up to YTL 500,000.[112] Despite reports from the Turkish Football Federation, the Turkish police believe that football hooliganism is not a major threat and are "isolated incidents".[113]
Before Galatasaray's semi-final UEFA Cup match with Leeds United in 2000, two Leeds fans, Christopher Loftus and Kevin Speight, were stabbed to death in Istanbul following street fights between Turkish and British hooligans.[108] UEFA allowed the game to proceed and Galatasaray won 2–0. Leeds complained because home fans jeered while a message of condolence was read for the victims.[114] Galatasaray's players refused to wear black arm bands. The Leeds chairman at the time, Peter Ridsdale, accused Galatasaray of "showing a lack of respect".[115] He also revealed that his teams' players had received death threats before the match.[116]
Ali Ümit Demir was arrested and sentenced to 15 years imprisonment for the stabbing, but the sentence was reduced to 5 years on the basis of heavy provocation, while five others were given lesser sentences of under four months.[113] The families of those accused of attacking with knives are reported to have defended their actions and approved of their children punishing the "rude British people".[108] Galatasaray fans were banned from traveling to the return match to try and avoid further clashes between fans, although there were reports of attacks by Leeds fans on Turkish television crews and the police.[117] However the Assistant Chief Constable in charge of policing the game believed that the number of arrests was "no worse than a normal high category game".[117]Hakan Şükür was hit with projectiles from Leeds United supporters and the Galatasaray team bus was stoned after driving through an underpass. The game saw Emre Belözoğlu and Harry Kewell sent off and Galatasaray sealed their way to the final with a 2–2 score.
Violence also occurred between Arsenal fans (mainly from The Herd) and Galatasaray fans before the 2000 UEFA Cup final in Copenhagen[118] in which a Galatasaray fan, an Arsenal fan and a Dane were said to have been stabbed.[119] Galatasaray later won the match after a penalty shoot-out.
On 24 May 2001, 50 people were injured when fighting broke out at a match between French club PSG and Galatasaray at the Parc des Princes stadium.[16][17]PSG were initially given a record $571,000 fine, but it was reduced on appeal to $114,000. Galatasaray was initially fined $114,000 by UEFA, but it too was eventually reduced to $28,500.[18] In May 2001, six PSG fans from the Supporters Club, were arrested and charged with assault, carrying weapons, throwing items on the pitch and racism. The six were alleged to have deliberately entered a part of the Parc des Princes stadium where French fans of Turkish origin were standing, in order to attack them. The six were banned from all football stadiums for the duration of their trial.
On 3 June 2011, after the Belgium vs. Turkey match, several riots occurred in the city center of Ghent after a 1–1 draw.30 people were injured. Hooliganism in Turkey is also a problem in Ankara, İzmir, Eskişehir, Bursa, Samsun and Adana[citation needed]. During the 2003–2004 season, a Second League Category A, match between Karşıyaka and Göztepe on 8 February 2004, involved rival Karşıyaka and Göztepe supporters clashing and the match was subsequently stopped for 33 minutes. This was due to Karşıyaka leading 5–2 after coming back from a 2–0 deficit. After the match, Göztepe fans clashed with the police, seven police officers were wounded and fifteen Göztepe fans were arrested.[120]
On 7 May 2011, Bursaspor supporters clashed with the police ahead of the team's match with rival Beşiktaş. 25 police officers and 9 fans were injured in the violence.[123] A Trabzonspor fan pointed a gun to the bus which carried the players of Fenerbahçe. During the Fenerbahçe-Galatasaray game at the end of 2011–2012 season Fenerbahçe fans clashed with the police the damage costed about 2 million dollars.Buses were stoned,Police cars set on fire and trees were set on fire by Fenerbahçe fans.This was described as a warzone.
The 1967 Kayseri Atatürk Stadium Disaster was the worst hooliganism event that has ever happened in Turkey. It resulted in 40 deaths and some 600 were injured. The violence started following provocation of the Kayserispor fans in the half time, whose team went to leading by a goal scored in the first half.Supporters of the two teams threw rocks to each other.Some of the hooligans were also armed with bats and knives.The fleeing crowd caused a stampede in front of the stand exits.The events in the stadium were followed by vandalism in Kayseri and many-days lasting riots in Sivas. Hooliganism is also an issue in other sports like Basketball and Volleyball in Turkey.
On 13 May 2013, a Fenerbahce fan was stabbed to death after the Istanbul derby. The Fenerbahce fan was on his way back home after the match between Fenerbahçe and Galatasaray, when he was attacked by a group of Galatasaray fans at a bus stop, and died in hospital later.[124]
In 2015, confectioners Ülker–previously "one of Turkish football's biggest sponsors"–ceased their support, reportedly due to "low crowds, violence and poor atmosphere at matches".[125]
