Jawhar ibn Abdallah, surnamed al-Siqilli ("the Sicilian"), al-Rumi ("the Greek"), al-Saqlabi ("the Slav"), al-Katib ("the Chancellor") and al-Qaid ("the General"), (Arabic: جوهر الصقلي , born early 10th century, died 992), was the most important military leader in Fatimid history. He led the conquest of North Africa and then of Egypt, founded the city of Cairo and the great al-Azhar mosque.
Jawhar was a Sicilian ghulam[clarification needed] of Greek ethnicity. His family originated from the Emirate of Sicily (hence the epithet الصقلي = the Sicilian), and came as a slave to North Africa. He was sent to the Caliph Ismail al-Mansur on account of his intelligence and cunning. Under his son al-Muizz (953-975) he gained his freedom and became his personal secretary. Soon he was Vizir and the highest-ranking military commander of the Fatimids. In this role he resumed the expansion of the Fatimids and, together with the Zirids, conquered Fez in Northern Morocco, and pushed towards the Atlantic. Only the strongholds of Ceuta and Tangier could be retained by the Umayyads of Córdoba.
After the Western borders had been secured, Jawhar as-Siqilli pushed towards Egypt and occupied the land around the Nile from the Ikhshidids after a siege at Giza. The conquest was prepared by a treaty with the Vizir of the Ikhshidids (by which Sunnis would be guaranteed freedom of religion), so the Fatimids encountered little resistance. Afterwards Jawhar ruled Egypt until 972 as viceroy.
In this capacity he founded the city of Cairo on 969 north of Fostat, to serve as the new residence of the Fatimid Caliphs, and the al-Azhar mosque in 970. Although Palestine was occupied after the conquest of Egypt, Syria could not be overcome, following a defeat at the hands of the Carmathians at Damascus. However, when the Carmatians overran Egypt, Jawhar was able to defeat them north of Cairo on the 22 December 970, although the struggle continued until 974. To secure the southern border of Egypt a legation was sent to the Christian land of Nubia.
After the establishment of the residence at Cairo, Jawhar fell into disfavour with al-Muizz. Under his successor al-Aziz (975-996) however, in whose accession to the throne Gawhar played an important role, he was rehabilitated. He was regent again until 979, but was finally stripped of power after a campaign against Syria was once again defeated near Damascus. Gawhar died on February 1, 992.

"Under Mu’izz (955-975) the Fatimids reached the height of their glory, and the universal triumph of isma ‘ilism appeared not far distant. The fourth Fatimid Caliph is an attractive character: humane and generous, simple and just, he was a good administrator, tolerant and conciliatory. Served by one of the greatest generals of the age, Jawhar al-Rumi, a former Greek slave, he took fullest advantage of the growing confusion in the Sunnite world."
