Mu'awiya I was the founder and first caliph of the Umayyad Caliphate, ruling from 661 until his death. He became caliph less than thirty years after the death of the Islamic prophet Muhammad and immediately after the four Rashidun ('rightly-guided') caliphs. Unlike his predecessors, who had been close, early companions of Muhammad, Mu'awiya was a relatively late follower of Muhammad.
Nubians are a Nilo-Saharan speaking ethnic group indigenous to the region which is now northern Sudan and southern Egypt. They originate from the early inhabitants of the central Nile valley, believed to be one of the earliest cradles of civilization. In the southern valley of Egypt, Nubians differ culturally and ethnically from Egyptians, although they intermarried with members of other ethnic groups, especially Arabs. They speak Nubian languages as a mother tongue, part of the Northern Eastern Sudanic languages, and Arabic as a second language.
Makuria was a medieval Nubian kingdom in what is today northern Sudan and southern Egypt. Its capital was Dongola in the fertile Dongola Reach, and the kingdom is sometimes known by the name of its capital.
The Baqt (بقط) was a 7th-century treaty between the Christian state of Makuria and the new Muslim rulers of Egypt. Lasting almost seven hundred years, it is by some measures the longest-lasting treaty in history. The name comes either from the Egyptian's term for barter, or the Greco-Roman term for pact.
Banu Kanz, also known as Awlad Kanz, was a semi-nomadic Muslim dynasty of Arab descent that ruled the border region between Upper Egypt and Nubia between the 10th and 15th centuries. They were descended from the sons of sheikhs of the Arab Banu Hanifa tribe who intermarried with the princesses of the Beja Hadariba tribe. They gained official control over the region of Aswan, Wadi Allaqi and the frontier zone in the early 11th century when their chief, Abu al-Makarim Hibatallah, captured a major rebel on behalf of the Fatimid authorities. Abu al-Makarim was accorded the title Kanz al-Dawla by Caliph al-Hakim and his successors inherited the title. The Banu Kanz entered into conflict with the Ayyubids in 1174, during which they were defeated and forced to migrate southward into northern Nubia, where they helped accelerate the expansion of Islam in the mostly Christian region. They eventually assumed control of the Nubian Kingdom of Makuria in the early 14th century, but by the early the 15th century, they were supplanted by the Hawwara tribesmen dispatched by the Mamluks to combat the Banu Kanz. Their modern-day descendants are a Sudanese tribe known as the "Kunuz", who live in the far north of the country.
The Exarchate of Africa was a division of the Byzantine Empire around Carthage that encompassed its possessions on the Western Mediterranean. Ruled by an exarch (viceroy), it was established by the Emperor Maurice in 591 and survived until the Muslim conquest of the Maghreb in the late 7th century. It was, along with the Exarchate of Ravenna, one of two exarchates established following the western reconquests under Emperor Justinian I to administer the territories more effectively.
The Arab–Byzantine wars were a series of wars from the 7th to 11th centuries between multiple Arab dynasties and the Byzantine Empire. The Muslim Arab Caliphates conquered large parts of the Christian Byzantine empire and unsuccessfully attacked the Byzantine capital of Constantinople. The frontier between the warring states remained almost static for three centuries of frequent warfare, before the Byzantines were able to recapture some of the lost territory.
ʿUqba ibn Nāfiʿ ibn ʿAbd al-Qays al-Fihrī al-Qurashī, also simply known as Uqba ibn Nafi, was an Arab general serving the Rashidun Caliphate since the reign of Umar and later the Umayyad Caliphate during the reigns of Mu'awiya I and Yazid I, leading the Muslim conquest of the Maghreb, including present-day Libya, Tunisia, Algeria and Morocco and a failed attempt in Nubia. He is credited with establishing Umayyad rule in North Africa. Uqba was the nephew of Amr ibn al-As. He is often surnamed al-Fihri in reference to the Banu Fihr, a clan connected to the Quraysh. His descendants would be known as the ʿUqbids or Fihrids.
The Arab conquest of Egypt, led by the army of 'Amr ibn al-'As, took place between 639 and 642 AD and was overseen by the Rashidun Caliphate. It ended the seven-century-long Roman period in Egypt that had begun in 30 BC and, more broadly, the Greco-Roman period that had lasted about a millennium.
Islamic rule in Tripolitania and Cyrenaica began as early as the 7th century. With tenuous Byzantine control over Libya restricted to a few poorly defended coastal strongholds, the Arab invaders who first crossed into Pentapolis, Cyrenaica in September 642 encountered little resistance. Under the command of Amr ibn al-A'as, the armies of Islam conquered Cyrenaica, renaming the Pentapolis, Barqa.
Umar was the second Rashidun Caliph and reigned during 634–644. Umar's caliphate is notable for its vast conquests. Aided by brilliant field commanders, he was able to incorporate present-day Iraq, Iran, Azerbaijan, Armenia, Georgia, Syria, Jordan, Palestine, Lebanon, Egypt, and parts of Afghanistan, Turkmenistan and south western Pakistan into the Caliphate. During his reign, the Byzantines lost more than three fourths of their territory and in Persia, Umar became the king (ruler) of Iran after the fall of the Sassanid Empire.
The Rashidun Caliphate was the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE. During its existence, the empire was the most powerful economic, cultural, and military force in West Asia and Northeast Africa.
The Rashidun army was the core of the Rashidun Caliphate's armed forces during the early Muslim conquests in the 7th century. The army is reported to have maintained a high level of discipline, strategic prowess and organization, granting them successive victories in their various campaigns.
The 3rd Rashidun Caliph, Uthman continued the policy of military expansion carried out by his predecessors, Umar and Abu Bakr. During his reign, the caliphate stretched from Tripolitania, Egypt, and Anatolia to Greater Khorasan and Sindh and reached its greatest extent in 654 CE. However, these conquests were halted when a rebellion began in Egypt which led to his murder, and began the first Fitna.
The second battle of Dongola or siege of Dongola was a military engagement between early Arab forces of the Rashidun Caliphate and the Nubian-Christian forces of the kingdom of Makuria in 652. The battle ended Muslim expansion into Nubia, establishing trade and a historic peace between the Muslim world and a Christian nation. As a result, Makuria was able to grow into a regional power that would dominate Nubia for over the next 500 years.
Umayyad rule in North Africa or Umayyad Ifriqiya was a province of the Umayyad Caliphate (661–750) during the historical period in which it ruled the Maghreb region of North Africa, from its conquest of the Maghreb starting in 661 to the Kharijite Berber Revolt ending in 743, which led to the end of its rule in the western and central Maghreb. Following this period, the Umayyads retained their rule over Ifriqiya while the rest of the Maghreb fell to successive Islamic dynasties of Arab, Berber and Persian descent.
Slavery in the Rashidun Caliphate refers to the chattel slavery taking place in the Rashidun Caliphate (632–661), a period when the Islamic Caliphate was established and the Islamic conquest expanded outside of the Arabian Peninsula.
