Najaf (Arabic: النجف; BGN: An Najaf) is a city in Iraq about 160 km south of Baghdad. Its estimated population in 2008 is 900,600 people. It is the capital of Najaf Governorate. It is one of the holiest cities of Shia Islām and the center of Shia political power in Iraq.
Najaf's religious significance
Najaf is renowned as the site of the tomb of Alī ibn Abī Tālib (also known as "Imām Alī"), the cousin and son-in-law of the prophet Muhammad whom the Shia consider to be the righteous caliph and first imām. The city is now a great center of pilgrimage from throughout the Shi'a Islamic world. It is estimated that only Mecca and Medina receive more Muslim pilgrims.
The Imām Alī Mosque is housed in a grand structure with a gilded dome and many precious objects in the walls. Nearby is the Wādī as-Salām "Wadi of Peace", claimed to be the largest cemetery in the Muslim world (and possibly the largest in the entire world), containing the tombs of several prophets. Many of the devout from other lands aspire to be buried here, to be raised from the dead with Imām Alī on Judgement Day. Over the centuries, numerous hospices, schools, libraries and Sufi convents were built around the shrine to make the city the centre of Shīˤa learning and theology.
The Najaf seminary is one of the most important teaching centres in the Islamic world. Ayatollah Khomeini lectured there from 1964-1978.  Many of the leading figures of the new Islamic movement that emerged in Iraq, Iran and Lebanon in the 1970s had studied at Najaf. 
Much of Najaf's heritage was badly damaged during the rule of Saddam Hussein, with a highway being driven through the middle of the Wādī'u s-Salām.
The Najaf area is located 30 km south of the ancient city of Babylon and 400 km north of the ancient Biblical city of Ur. The city itself was reputedly founded in 791 by the Abbasid Caliph Harūn ar-Rashīd, as a shrine to Ali ibn Abi Talib. 
Ali ibn Abi Talib instructed that his burial place should remain a secret as he had many enemies and he feared that his body might be subjected to some indignity. According to legend the dead body of Ali was placed on a camel which was driven from Kufa. The camel stopped a few miles west of the city and here the body was secretly buried. No tomb was raised and nobody knew of the burial place except for a few trusted people. It is narrated that more than a hundred years later the Abbasid Caliph, Harun al-Rashid, went deer hunting outside Kufa and the deer sought sanctuary at a place where the hounds would not pursue it. On inquiry as to why the place was a sanctuary Harūn ar-Rashīd was told that it was the burial place of Ali. Harūn ar-Rashīd ordered a mausoleum to be built on the spot and in due course the town of Najaf grew around the mausoleum.
Under the rule of the Ottoman Empire Najaf experienced severe difficulties as the result of repeated raids by Arab desert tribes and acute water shortages caused by the lack of a reliable water supply. The number of inhabited houses in the city had plummeted from 3000 to just 30 by the start of the 16th century.
The city was besieged by the Wahhabis in the late 18th century, which prompted the clergy of the city to arrange for the construction of a wall around the city and under-ground tunnels as a refuge for the women and children if the wall was over-run. These fortifications successfully repelled a Wahhabi siege later on. The water shortages were finally resolved in 1803 with the construction of the Hindiyya canal, following which the city's population rapidly doubled from 30,000 to 60,000.
The Ottomans were expelled in an uprising in 1915, following which the city fell under the rule of the British Empire. The sheikhs of Najaf rebelled in 1918, killing the British governor of the city by Sayed Mahdi Al-Awadi and cutting off grain supplies to the Anaza, a tribe allied with the British. In retaliation the British besieged the city and cut off its water supply. The rebellion was put down and the rule of the sheikhs was forcibly ended. A great number of the Shia ulema were expelled into Persia/Iran where they set the foundations for the rise of the city of Qom as the center of the Shia learning and authority in lieu of Najaf. Najaf lost its religious primacy to Qom and was not to regain it until the 21st century and the establishment of a Shia-majority government in Iraq after 2003.

</table> Najaf was regarded with suspicion by the Sunnī-dominated regime of Saddam Hussein, which suppressed and restricted Shia religious activities. At the end of the Gulf War in 1991, people revolted against the regime's suppression and the destruction that it led the country into. This was put down by the Iraqi military with severe brutality and damage to the city, damaging the golden dome, slaughtering several innocent people who took refuge in the shrine and causing several others to disappear. Much of the damage was not repaired after several years, which was considered to be a collective punishment. In February 1999, One of Najaf's most senior clerics, Muħammad Sādiq as-Sadr, was assassinated along with his two sons on the way from Baghdad to Najaf - the third killing of Shiite clerics in less than a year. Although the Iraqi government claimed to have caught and executed the supposed killers, there was evidence that Saddam's regime carried out the assassination, especially since it occurred in a country with very tight security and surveillance. One of his surviving sons, Moqtada al-Sadr, has assumed a prominent political role, mostly after the 2003 Iraq war, despite his relative paucity of formal theological credentials.
Najaf after the fall of Saddam
During the 2003 invasion of Iraq, Najaf was a key target of the invading United States forces. The city was encircled during heavy fighting on March 26, 2003 and was captured on April 3, 2003 by 1st, 2nd, 3rd Battalions, 327th Infantry Regiment, units of the 101st Airborne Division.
On August 29, 2003 a car bomb exploded during prayers outside the Imām Alī Mosque just as weekly prayers were ending. More than 80 people were killed, including the influential cleric Ayatollah Sayyid Muħammad Bāqir al-Ħakīm, the Shīia leader of the Supreme Council for the Islamic Revolution in Iraq (SCIRI). Dozens of others were injured. Nobody claimed responsibility for the attack - Saddam himself, in hiding at the time, denied any involvement in a taped message. On April 4, 2004, the Mahdi Army attacked the Spanish-Salvadoran-ALARNG base(FOB) in Najaf, part of a coordinated uprising across central and southern Iraq in an apparent attempt to seize control of the country ahead of the June 30, 2004 handover of power to a new Iraqi government. This uprising led to the 1st Armored Division's Task Force 2nd Battalion, 37th Armor (2-37 AR) attached to the 2 Armored Cavalry Regiment (2ACR) arriving in the city in the wake of the Spanish withdrawal. The situation aroused grave concerns among the Shia community of Iraq and Iran, as firefights took place within yards of the Kufa Mosque. Some mosques suffered superficial damage in the process, mostly due to Mahdi Army fighters mishandling explosives stored in the Kufa Mosque. Firefights between the Mahdi Army and Badr Organization took place in May as tensions rose over the Mahdi Army's occupation of the Imam Ali Shrine, looting of the mosques in their control, and illegal prisons and Sharia courts. The Najaf cemetery, the largest cemetery in the world, became a battle ground in May 2004 as M1A1 tanks from 2-37 AR fought Mahdi Army elements on the outskirts of the cemetery. The Mahdi Army stationed several three man rocket propelled grenade RPG teams in the cemetery, who lived in large tombs to avoid detection from U.S. helicopters and UAVs.
In August 2004, fighting broke out again between American troops of the 11th Marine Expeditionary Unit, the 1st Cavalry Division's 1st Battalion, 5th US Cavalry Regiment and 2nd Battalion, 7th US Cavalry Regiment, 15th Forward Support Battalion and Al-Sadr's Mahdi Army. The battle, which was mostly centered around Wādī' as-Salām Cemetery and the southwestern portion of the city, lasted three weeks and ended when senior Iraqi cleric Grand Ayatollah Alī Al-Sīstānī negotiated an end to the fighting. The evening before Al-Sistani arrived in the city, two F-16's, flying out of Balad, dropped four two-thousand pound JDAMs (Joint Direct Attack Munitions) on two hotels in close proximity to the Imam Ali Shrine. The success of this airstrike dealt a devastating blow to the insurgents holed up in one of the holiest shrines in the Islamic faith.
in last 6 years, Najaf city has lived in save environment and never witness any securities problems and every day more that 5000 visitors have came from Iran and Pakstan and some arab countries to visiting the tomb of Imam Ali the cousin of Islam prophet Mohammed
