Through Afghanistan, United Nations Security Council and NATO

ISAF's initial mandate was to secure the Afghan capital of Kabul and its surrounding area against opposition forces to facilitate the formation of the Afghan Transitional Administration headed by Hamid Karzai. In 2003, NATO took command of the mission at the request of the UN and Afghan government, marking its first deployment outside Europe and North America. Shortly thereafter, the UN Security Council expanded ISAF's mission to provide and maintain security beyond the capital region. ISAF incrementally broadened its operations in four stages, and by 2006 took responsibility for the entire country; ISAF subsequently engaged in more intensive combat in southern and eastern Afghanistan.

At its peak between 2010 and 2012, ISAF had 400 military bases throughout Afghanistan (compared to 300 for the ANSF) and roughly 130,000 troops. Forty-two countries contributed troops to ISAF, including all 30 members of NATO. Personnel contributions varied greatly throughout the mission: Canada was the largest contributor initially, though by 2010 the United States accounted for most troops, followed by the United Kingdom, Turkey, Germany, France, and Italy; Georgia, Denmark, Norway, and Estonia were among the largest contributors per capita. The intensity of the combat faced by participating countries varied greatly, with the U.S. sustaining the most casualties overall, while British, Danish, Estonian, Georgian, and U.S. forces suffered the most deaths for their population; Georgian Armed Forces had the highest per-capita casualty rate among coalition members.

Under its ultimate aim of transitioning security responsibilities to Afghan forces, ISAF ceased combat operations and was disbanded in December 2014. Several troops remained to serve a supporting and advisory role as part of its successor organization, the Resolute Support Mission.

Jurisdiction

For almost two years, the ISAF mandate did not go beyond the boundaries of Kabul. According to General Norbert Van Heyst, such a deployment would require at least ten thousand additional soldiers. The responsibility for security throughout the whole of Afghanistan was to be given to the newly reconstituted Afghan National Army. However, on 13 October 2003, the Security Council voted unanimously to expand the ISAF mission beyond Kabul with Resolution 1510. Shortly thereafter, Canadian Prime Minister Jean Chrétien said that Canadian soldiers (nearly half the entire force at that time) would not deploy outside Kabul.

On 24 October 2003, the German Bundestag voted to send German troops to the region of Kunduz. Approximately 230 additional soldiers were deployed to that region, marking the first time that ISAF soldiers operated outside of Kabul. After the Afghan parliamentary election in September 2005 the Canadian base Camp Julien in Kabul closed, and the remaining Canadian assets were moved to Kandahar as part of Operation Enduring Freedom in preparation for a significant deployment in January 2006. On 31 July 2006, the NATO‑led International Security Assistance Force assumed command of the south of the country, ISAF Stage 3, and by 5 October, also of the east of Afghanistan, ISAF Stage 4.

ISAF was mandated by UN Security Council Resolutions 1386, 1413, 1444, 1510, 1563, 1623, 1659, 1707, 1776, and 1917 (2010). The last of these extended the mandate of ISAF to 23 March 2011.
