Political violence in Turkey became a serious problem in the late 1970s and was even described as a "low-level civil war". Far-left groups such as Revolutionary People's Liberation Party/Front, and separate Maoist groups , also Turkish right-wing ultranationalist gangs (sometimes allied with the state), were responsible for most of the violence. Ultimately, over 5,000 people died in the conflict. The violence lessened for a while after the 1980 Turkish coup d'état and was later overshadowed by the PKK insurgency in 1984.

Background The Democrat Party, right-wing force that united conservatives, traditionalists, Islamists, nationalists, liberals, and urban bourgeoisie under one roof and was the dominant party throughout the 1950s, was banned after the 1960 coup d'état and its leaders such as prime minister Adnan Menderes were hanged. Intellectuals, politicians and the masses on the right fell into moral defeat as a result of these developments.

With the increase in infrastructure and transportation investments after the 1960 coup, the urban population grew, industrialization accelerated, and workers and their families who earned a living via performing labor became numerous. Class consciousness increased. The Right to unionize was granted with the 1961 Constitution. Under the influence of these developments, the Turkish left strengthened. 1961 Constitution essentially allowed ideological politics. In this environment of freedoms guaranteed, by the constitution students inclined to the Workers' Party of Turkey () founded their political associations. Left-wing book and magazines were translated, and political literature became more accessible. This situation became a threat to the right which began to mobilize its own forces to fight against communism.

Due to increasing political tensions and high inflation during social changes in the late 1960s and early 1970s, consumption was restricted to a limited group, and unemployment rose despite the growth of the labor force, and migration to Europe increased due to a lack of jobs (see Gastarbeiter). While the number of unionized workers increased, the number of unemployed people under the age of 30 reached alarming rates. In the 1960s, workers became militant in their struggle for higher wages and better working conditions. The struggle between employers and workers intensified with strikes and lockouts. As a result, in 1967, some unionists left Confederation of Turkish Trade Unions (TÜRK-İŞ) (), which they saw as pro-Justice Party (), and founded the radical left-wing Confederation of Revolutionary Trade Unions of Turkey (). While TÜRK-İŞ was established according to the American model and prioritized political tendencies by concentrating on economic demands; DİSK, on the other hand, got closer to Workers' Party of Turkey (TİP) by claiming that economic demands could be won through political struggle, based on the European example. As a result of this division, TÜRK-İŞ weakened.

With the increase in the number of students, schools and higher education, institutions became gathering places for political groups on the left and right sides.

In the absence of liberal solutions for countries whose main problem was development, such as Turkey, the intellectuals of the period were largely interested in the socialist model. Many intellectuals signed the manifesto proposing a socialist model in the first issue of Yön magazine, published in 1961. Under these influences, changes were taking place in the value system and status scale of ideologies in Turkey in the 1960s. Workers' Party of Turkey won 14 seats in the 1965 general election thanks to the national remnant and gained an important place in politics. Although it received a similar number of votes with the changed election system in the 1969 elections, its presence was reduced to three.

While Turkey, which is also a member of NATO, became a frontline country in the Cold War, various socialist regimes were established through coups in the south and in the Mediterranean region. From the right-wing perspective, while Turkey was surrounded from both the north and south, the loss of state authority in Istanbul for two days, starting in the industrial zones of Kocaeli and Istanbul, during the great workers' protest led by DİSK on 15-16 June 1970, was frightening for the right.

Some of the state elite, out of concern about the rise of the left, supported the far-right. Due to this support, left-leaning writers and journalists claimed that the Grey Wolves (officially the Idealist Hearths, ) were established and protected by the state in the late 60s to wage an armed struggle against the left.

In 1975 Süleyman Demirel, chairman of the conservative Justice Party (, AP) succeeded Bülent Ecevit, chairman of the now social-democratic Republican People's Party (, CHP) as Prime Minister. He formed a coalition, the Nationalist Front (), with Necmettin Erbakan's Islamist National Salvation Party (, MSP), and Alparslan Türkeş' far-right Nationalist Movement Party (, MHP). The MHP used the opportunity to infiltrate state security services, seriously escalating the low-intensity civil war that had been waging between rival factions.Gil, Ata. "La Turquie à marche forcée", Le Monde diplomatique, February 1981.

The elections of 1977 had no clear winner, as CHP didn't have a majority to form a government, and the right-wing parties all had to work together to form another coalition. Demirel at first continued the coalition with the Nationalist Front, but in 1978, Ecevit came to power again with the help of defectors from the AP, in a controversial event called the Güneş Motel Incident. In 1979, Demirel once again became prime minister. At the end of the 1970s, Turkey was in an unstable situation with unsolved economic and social problems and facing large strike actions and partial paralysis of parliamentary politics (the Grand National Assembly of Turkey was unable to elect a president during the six months preceding the coup). Since 1969, proportional representation had made it difficult for one party to achieve a parliamentary majority. The interests of the industrial bourgeoisie, who were economically dominant, were opposed by other social classes, such as smaller industrialists, tradesmen, rural notables and landlords, whose interests did not always coincide among themselves. Numerous agricultural and industrial reforms sought by parts of the upper-middle classes were blocked by others. The politicians seemed unable to combat the growing violence in the country. Even the police force was divided, with some police officers becoming members of left-wing and others being members right-wing unions. The left-wing police officers' union Pol-Der, had grown quite large, at one point having 18.000 members. In response, a right-wing police officers' union was formed, and the two unions' members were in conflict. The right and left-wing police officers would frequently report each other for administrative sanctions. The right-wing police members would intimidate and beat citizens that reported right-wing terrorists, and the left-wing police officers would intimidate citizens that reported crimes by left-wing militants, causing chaos.

Sequence of events Unprecedented political violence erupted in Turkey in the late 1970s. The overall death toll of the 1970s is estimated at 5,000, with nearly ten assassinations per day. Most were members of left-wing and right-wing political organizations, which were then engaged in bitter fighting. The ultranationalist Grey Wolves, the youth organisation of the MHP, claimed they were supporting the security forces. According to the British Searchlight magazine, in 1978 there were 3,319 right-wing attacks, in which 831 were killed and 3,121 wounded.Searchlight (magazine), No.47 (May 1979), pg. 6. In the central trial against the left-wing organization Devrimci Yol (Revolutionary Path, abbreviated as DEV-YOL) at the Ankara Military Court, the defendants listed 5,388 political killings before the military coup. Among the victims were 1,296 right-wingers and 2,109 left-wingers. The others could not clearly be related.Devrimci Yol Savunması (Defense of the Revolutionary Path). Ankara, January 1989, p. 118-119. The 1978 Bahçelievler massacre, the 1977 Taksim Square massacre with 35 victims and the 1978 Maraş massacre with over 100 victims are some notable incidents. Martial law was announced following the Maraş massacre in 14 of the then 67 provinces in December 1978. On the eve of the 12 September 1980 coup, martial law had been extended to 20 provinces. Nationalist Movement Party members were also murdered throughout Turkey, in one instant, the Gaziosmanpaşa local chairman for the MHP was murdered alongside his wife and children in Istanbul . MHP minister of Customs Gün Sazak was also assassinated by left-wing militants. . The People's Liberation Party-Front of Turkey claimed responsibility for killing several MHP members, bombing local MHP offices, and bombing police headquarters. In several incidents, members of left-wing organizations were in conflict with each other, with Revolutionary People's Liberation Party/Front compiling a list of incidents where murders occurred within the left, and accusing militant left-wing People's Liberation Party-Front of Turkey of shooting and killing members of other left-wing political organizations, or reporting them to the authorities.

Ecevit was warned about the coming coup in June 1979 by Nuri Gündeş of the National Intelligence Organization (MİT). Ecevit then told his interior minister, İrfan Özaydınlı, who then told Sedat Celasun, one of the five generals who would lead the coup. The deputy undersecretary of the MİT, Nihat Yıldız, was demoted to the London consulate and replaced by a lieutenant general as a result.

Kurdish separatism The right-wing groups were opposed to Kurdish separatism. Disproportionate numbers of Kurds were part of the left-wing groups. Before the 1980 military coup, the majority of violent clashes were between leftist and rightist groups, though the separatist attacks against the Turkish forces increased afterwards.

An amendment of the electoral law in 1969 kept small parties on both sides to gain any seats in Parliament. This caused a public uprising, including the Kurdish resistance. Multiple Kurdish leftist organizations appeared in Turkey in the 1960s and 1970s that were ready to use violence as a political tool. Violence sparked especially in the second half of the 1970s. Throughout the years, a number of them fell apart or were banned altogether after the 1980 military coup. After becoming increasingly involved in political activism after its foundation in 1978, the Kurdistan Workers' Party (PKK) led by Abdullah Öcalan would rise quickly to be one of the major separatist actors. As a militant political organisation, the PKK claimed 354 lives between the years 1978 and 1980. Most of the victims were ethnic Kurds as they constituted PKK's main target group. For example, feudal leaders were against the PKK's goals and values, which was why the PKK fought against them. Also, the PKK attempted to be the sole leftist power in the region, and thus fought against other leftist groups.

The Kurdistan Worker's Party did not only use violence to mobilise people during this time period. However, their use of violence did appeal to larger crowds, increasing the popularity of the party. By gaining more people to support them, other organisations were not able to gain similar status as the PKK did. Thus, the PKK was the main access of the Kurdish to political participation in Turkey. One way of involving a larger number of people in its activities was to include women, which challenged the traditional gender relations in the country.
