The occupation of Iraq (2003–2011) began on 20 March 2003, when the United States invaded with a military coalition to overthrow Iraqi president Saddam Hussein and his Arab Socialist Ba'ath Party, and continued until 18 December 2011, when the final batch of American troops left the country. While the United States, the United Kingdom, and Australia were the largest contributors to the coalition, 29 other countries, such as Japan, were involved in the Iraq War in a lesser capacity. Additionally, several private military contractors took part in enforcing the occupation.
Muqtada al-Sadr is an Iraqi Shia Muslim cleric, politician and militia leader. He inherited the leadership of the Sadrist Movement from his father. He founded the now dissolved Mahdi Army militia in 2003 that resisted the American occupation of Iraq. He also founded the Promised Day Brigade militia after the dissolution of the Mahdi Army; both were backed by Iran. In 2014, he founded the Peace Companies militia and is its current head. In 2018, he joined his Sadrist political party to the Saairun alliance, which won the highest number of seats in the 2018 and 2021 Iraqi parliamentary elections.
Events in the year 2004 in Iraq.
The Mahdi Army was an Iraqi Shia militia created by Muqtada al-Sadr in June 2003 and disbanded in 2008.
An Iraqi insurgency began shortly after the 2003 American invasion deposed longtime leader Saddam Hussein. It is considered to have lasted until the end of the Iraq War and U.S. withdrawal in 2011. It was followed by a renewed insurgency.
After the 2003 invasion of Iraq was completed and the regime of Saddam Hussein was toppled in May 2003, an Iraqi insurgency began that would last until the United States left in 2011. The 2003–2006 phase of the Iraqi insurgency lasted until early 2006, when it escalated from an insurgency to a Sunni-Shia civil war, which became the most violent phase of the Iraq War.
After the handover of sovereignty, Operation Squeeze Play was a combined U.S./Iraqi sweep of the western suburbs of Baghdad launched on 22 May 2005. Almost 300 suspects were detained in the first day of the operation.
The Iraqi civil war was an armed conflict from 2006 to 2008 between various sectarian Shia and Sunni armed groups, such as the Islamic State of Iraq and the Mahdi Army, in addition to the Iraqi government alongside American-led coalition forces. In February 2006, the insurgency against the coalition and government escalated into a sectarian civil war after the bombing of Al-Askari Shrine, considered a holy site in Twelver Shi'ism. US President George W. Bush and Iraqi officials accused Al-Qaeda in Iraq (AQI) of orchestrating the bombing. AQI publicly denied any links. The incident set off a wave of attacks on Sunni civilians by Shia militants, followed by attacks on Shia civilians by Sunni militants.
At approximately 6:44 a.m. Arabia Standard Time on 22 February 2006, al-Askari Shrine in Samarra, Iraq, was severely damaged in a bombing attack amidst the then-ongoing Iraq War. Constructed in the 10th century, it is one of the holiest sites in Shia Islam. Despite the magnitude of the explosions, there were no casualties. American president George W. Bush asserted that the bombing had been carried out by Al-Qaeda in Iraq, which denied involvement in the attack.
The following lists events that happened during 2006 in Iraq.
The Iraq War, also referred to as the Second Gulf War, was a prolonged conflict in Iraq lasting from 2003 to 2011. It began with the invasion by a United States-led coalition, which resulted in the overthrow of the Ba'athist government of Saddam Hussein. The conflict persisted as an insurgency arose against coalition forces and the newly established Iraqi government. US forces were officially withdrawn in 2011. In 2014, the US became re-engaged in Iraq, leading a new coalition under Combined Joint Task Force – Operation Inherent Resolve, as the conflict evolved into the ongoing insurgency.
Operation Together Forward, also known as Forward Together, was an unsuccessful offensive against sectarian militias in Baghdad to significantly reduce the violence in which had seen a sharp uprise since the mid-February 2006 bombing of the Askariya Mosque, a major Shiite Muslim shrine, in Samarra.
The 2006 Sadr City bombings were a series of car bombs and mortar attacks in Iraq that occurred on 23 November at 15:10 Baghdad time and ended at 15:55. Six car bombs and two mortar rounds were used in the attack on the Shia slum in Sadr City.
The 2004 Iraq spring fighting was a series of operational offensives and various major engagements during the Iraq War. It was a turning point in the war; the Spring Fighting marked the entrance into the conflict of militias and religiously based militant Iraqi groups, such as the Shi'a Mahdi Army.
Operation Imposing Law, also known as Operation Law and Order, Operation Fardh al-Qanoon or Baghdad Security Plan (BSP), was a joint Coalition-Iraqi security plan conducted throughout Baghdad. Under the Surge plan developed in late 2006, Baghdad was to be divided into nine zones, with Iraqi and American soldiers working side by side to clear each sector of Shiite militias and Sunni insurgents and establish Joint Security Stations so that reconstruction programs could begin in safety. The U.S. military commander in Iraq, David Petraeus, went so far as to say Iraq would be "doomed" if this plan failed. Numerous members of Congress stated the plan was a critical period for the U.S. presence in Iraq.
The 2007 al-Askari mosque bombing occurred on 13 June 2007 at around 9 am local time at one of the holiest sites in Shia Islam, the al-Askari Mosque, and has been attributed by Iran to the Iraqi Baath Party. While there were no injuries or deaths reported, the mosque's two ten-story minarets were destroyed in the attacks. This was the second bombing of the mosque, with the first bombing occurring on 22 February 2006 and destroying the mosque's golden dome.
The Battle of Basra began on 25 March 2008, when the Iraqi Army launched an operation to drive the Mahdi Army militia out of the southern Iraqi city of Basra. The operation was the first major operation to be planned and carried out by the Iraqi Army since the invasion of 2003.
The siege of Sadr City was a blockade of the Shi'a district of northeastern Baghdad carried out by US and Iraqi government forces in an attempt to destroy the main power base of the insurgent Mahdi Army in Baghdad. The siege began on 4 April 2004 – later dubbed "Black Sunday" – with an uprising against the Coalition Provisional Authority following the government banning of a newspaper published by Muqtada Al-Sadr's Sadrist Movement. The most intense periods of fighting in Sadr City occurred during the first uprising in April 2004, the second in August the same year, during the sectarian conflict that gripped Baghdad in late 2006, during the Iraq War troop surge of 2007, and during the spring fighting of 2008.
The Iraqi conflict is a series of violent events that began with the 2003 American-led invasion of Iraq and deposition of Iraqi president Saddam Hussein, the most recent of which is the ISIS conflict, in which the Iraqi government declared victory in 2017.
