Landmark dates in Afghanistan since the 2001 US-led invasion that ousted the Taliban from power, with the Islamists going on to launch a fierce insurgency.
- 2001: 'War on terror' -
President George W. Bush launches his "war on terror" -- a response to the September 11 attacks that killed around 3,000 people in New York, Washington and Pennsylvania -- with air strikes on Afghanistan on October 7, 2001.
The Taliban government had sheltered Osama bin Laden and his Al-Qaeda movement, which masterminded the strikes.
In power since 1996, the Taliban are soon defeated and flee the capital on December 6.
Hamid Karzai is appointed to lead an interim government and NATO begins to deploy its International Security Assistance Force (ISAF).
- 2004: First presidential election -
Afghanistan's first election based on universal suffrage is held on October 9, 2004 and Karzai wins 55 percent of votes on an enthusiastic turnout of 70 percent.
The Taliban regroup in the south and east, and also across the border in Pakistan, and launch an insurgency.
- 2008: US reinforcements -
As the attacks multiply, the US command in September 2008 asks for reinforcement of about 20,000 more US troops to join the 33,000 on the ground as part of the 70,000 combined NATO deployment.
Still engaged in Iraq, Bush sends 5,000 soldiers.
- 2009: Karzai re-elected -
Karzai is reelected in August 20, 2009 elections that are marred by massive fraud, a turnout of only 30-33 percent and Taliban attacks.
He takes 49.7 percent of votes in the first round and his challenger Abdullah Abdullah, a former minister, withdraws before the runoff.
On December 1 President Barack Obama -- elected on promises to end the Iraq and Afghanistan wars -- announces the deployment of 30,000 more US soldiers.
Bin Laden is killed on May 2, 2011 in a US special forces operation in Pakistan.
By 2012 more than 150,000 foreign soldiers are deployed in Afghanistan, of which 100,000 are American.
- June 2014: Ghani takes power -
On June 14, 2014 Ashraf Ghani is elected president with 56 percent of votes.
It is Afghanistan's first democratic transfer of power, with Karzai constitutionally barred from seeking another term.
The vote is marred by violence and a bitter dispute over claims of fraud.
- December 2014: NATO withdraws -
On December 31, 2014 the NATO alliance ends its 13-year combat mission in Afghanistan. About 12,500 foreign soldiers -- of which 9,800 are American -- remain to train Afghan troops and conduct anti-terrorist operations.
The following year the Taliban make their greatest military advances since they were removed from government.
The Islamic State (IS) group also becomes active. Bloody attacks multiply, notably in Kabul.
- 2018: Talks open -
Insurgency-linked violence claims a record number of lives in 2018, according to a UN tally which records at least 3,804 civilian deaths.
In mid-2018 Washington and Taliban representatives discreetly open talks in Doha focused on slashing the US military footprint in Afghanistan.
In return the US demands the Taliban prevent the country from being used as a safe haven for jihadist groups including Al-Qaeda.
Talks focus on a ceasefire and the opening of Taliban negotiations with the Kabul government.
But on September 7, 2019 US President Donald Trump abruptly calls off the talks after a US soldier is among 12 people killed in an attack in Kabul.
