There were many important dates and specific details to remember. In August 2014, the U.S. and Iran both began airstrikes in Iraq. 
Today, the world is much safer from this group than before. By 2020, the group's ability to hold land was mostly gone. 
The war against the Islamic State (IS) was a massive global effort to stop a militant group. In 2014, the Islamic State invaded parts of Iraq and Syria. They took over large amounts of territory very quickly. The group was widely condemned for human rights abuses and executions. This rapid expansion caused fear of the conflict spreading further. Because of these actions, many different nations decided to intervene.
To fight the group, several different coalitions were formed. The most prominent was a U.S.-led coalition known as Combined Joint Task Force – Operation Inherent Resolve (CJTF-OIR). This group was formally established in October 2014. Its mission was to formalize military actions against the rising threat. 
Many countries participated in these international efforts. In September 2014, the U.S. began working with Saudi Arabia and Jordan. They coordinated aerial bombing campaigns across both Iraq and Syria. 
Different nations had different roles and goals in the region. For example, Iran began flying drones and sending soldiers to Iraq in mid-June 2014.
On the ground, local militias received vital support from international forces. The U.S. and its allies trained and equipped secular groups. These included the Free Syrian Army and various Kurdish militias. 

The war saw significant changes in the group's control over land. By December 2017, IS was estimated to control no territory in Iraq. They only held about 5% of Syrian territory at that time. Iraq declared victory in its fight against the group on December 9, 2017. In March 2019, the group lost its last major territory in Syria after the Battle of Baghuz Fawqani. 
Even after losing their territory, the group did not disappear entirely. They transitioned into what is known as an insurgency. This means they began using smaller, hidden tactics to cause trouble. In October 2019, the group's leader, Abu Bakr al-Baghdadi, died during a U.S. special operations raid. He was later succeeded by Abu Ibrahim al-Hashimi al-Qurashi. By August 2020, it was estimated that over 10,000 fighters remained. These fighters mostly operated as sleeper cells in Syria and Iraq.
