There have been numerous incidents during the Hajj, the Muslim pilgrimage to the cities of Mecca and Medina, that have caused loss of life. Every follower of Islam is required to visit Mecca and Medina during the Hajj at least once in their lifetime, if able to do so; according to Islam, the pilgrimage is one of the Five Pillars of Islam. During the month of the Hajj, Mecca and Medina must cope with as many as three million pilgrims.

Mina, also known as Muna, and commonly known as the "City of the Tents" is a valley located 8 kilometres southeast of the city of Mecca, in the district of Masha'er, Province of Makkah in the Hejazi region Saudi Arabia. Covering an area of approximately 20 km2 (7.7 sq mi), Mina incorporates the tents, the area of Jamarat, and the slaughterhouses just outside the tents.
