The LTTE was formed in 1976

Peace talks in October have failed to bring an end to a 23-year civil war in Sri Lanka that has now claimed over 65,000 lives. Here are the main events in the conflict.

1948
Ceylon gains independence from British rule dating back to the end of the 18th century.

The population is comprised of a Sinhalese majority that can be traced back to the sixth century BC and a Tamil minority, mainly concentrated in the north of the country, who have roots reachnig back to the third century.

1956 Sinhalese is made the only official language in a series of Sinhalese nationalist measures introduced by the government.

1958 Riots erupt between the Sinhalese and Tamil communities that leave many people dead and force several thousand people, mainly Tamils, to relocate to the north.

1972 Ceylon is renamed Sri Lanka.

The Tamil New Movement is formed by Velupillai Prabhakaran, made up mainly of university students calling for greater equality in the grading system and more places in higher education. In 1975 they assassinate the mayor of Jaffna, marking the emergence of violence in the Tamil campaign.

1976 The Liberation Tigers of Tamil Eelam (LTTE) are formed from the Tamil New Movement and other student groups.

The concept for a separate Tamil state (Tamil Eelam) to be established in the north of the country is first proposed by the Tamil United Liberation Front (TULF).

Both sides have sustained heavy losses

1977 The TULF, a coalition of small parties, wins the majority of seats in Tamil areas in the country's elections, but the government later bans them from parliament for advocating an independent state.

More riots break out following an alleged assault by Tamils on Sinhalese policemen.

1983 Ethnic tensions in the country erupt into the start of a civil war when 13 soldiers are killed in an LTTE attack. The raid triggers anti-Tamil riots in Colombo and other parts of the country that leave thousands of people dead and force Tamils to leave Sinhalese majority areas.

1985 The first attempt at peace talks between the two sides fails.

1987 Government soldiers push LTTE fighters back to the northern city of Jaffna.

In the same year the LTTE carries out what is believed to be its first suicide bomb attack when a lorry is driven into an army camp and explodes, killing 40 soldiers.

The government signs the Indo-Sri Lanka peace accords that makes several concessions to the Tamil fighters, including recognising Tamil as an official language. India agrees to help keep order in the north and east of the country via a peace-keeping force and agrees to stop helping Tamil fighters.

1988 Indian troops leave the country as violence escalates between the warring parties.

1991 The former Indian prime minister, Rajiv Gandhi is assassinated by a suicide bomber who is believed to be a member of the LTTE.

One of the war's fiercest battles takes place at the Elephant Pass army base that controls access to the Jaffna peninsula. Thousands of LTTE fighters surround the base and lay siege to it for a month in a battle that leaves around 2,000 dead on both sides.

1993 The Sri Lanka president, Ranasinghe Premadasa is killed by an LTTE bomber.

Kuramatunga was Sri Lanka's  president for 11 years

1994 New president, Chandrika Kumaratunga, opens peace talks with the LTTE.

1995 The peace talks collapse and the government launches a major offensive that drives the separatists out of Jaffna. An estimated 400,000 civilians leave the town.

1996 Government troops launch another offensive and a further 200,00 people flee the violence.

Nintey people are killed and 1,400 injured when a LTTE suicide bomber attacks the central bank in Colombo. The government imposes a state of emergency.

1997 A separatist bomb attack damages the Temple of the Tooth in Kandy, the country’s holiest Buddhist site.

The government and some foreign administrations ban the LTTE in an effort to disrupt their fundraising.

1999 Kumaratunga loses one eye and sustains other injuries in a failed assassination attempt by the LTTE at an election rally.

April General elections are held early and the party of president Kumaratunga is unable to secure an overall majority in parliament. Mahinda Rajapakse becomes prime minister.

December More than 30,000 Sri Lankans are killed and tens of thousands left homeless by the Indian Ocean Tsunami. Arguments ensue almost immediately about whether the large amount of international aid is sent to mainly Tamil or Sinhalese areas.
