France had been on high alert for terrorism since the Charlie Hebdoshooting and a series of related attacks in January by militants belonging to Al-Qaeda in the Arabian Peninsula, and had increased security in anticipation of the 2015 United Nations Climate Change Conference, scheduled to be held in Paris at the beginning of December, as well as reinstating border checks a week before the attacks.

Throughout 2015, France witnessed smaller attacks: the February stabbing of three soldiers guarding a Jewish community centre in Nice, the June attempt to blow up a factory in Saint-Quentin Fallavier, and the August shooting and stabbing attack on a passenger train.

The Bataclan theatre had been threatened a number of times because of its public support for Israel. Two Jewish brothers, Pascal and Joël Laloux, owned the Bataclan for more than 40 years before selling it in September 2015. In 2011, a group calling itself Army of Islam told French security services they had planned an attack on the Bata clan because its owners were Jewish.

In the weeks leading up to the Paris attacks, ISIL and its branches had claimed responsibility for several other attacks: the downing of Metrojet Flight 9268 on 31 October and the suicide bombings in Beirut on 12 November.

Intelligence agencies in Turkey, Iraq and Israel had all warned of an imminent attack on France months beforehand, but were ignored by the French authorities.
