Spread of Islam in the context of "Adal Sultanate"

In world history, post-classical history refers to the period from about 500 CE to about 1450 or 1500 CE, roughly corresponding to the European Middle Ages following the decline of the western Roman Empire. The post-classical period is characterized by the expansion of certain civilizations geographically, by ongoing wars fought over land, resources and religion, and by the development of trade networks between often-distant civilizations. This period is also called—with various implications and emphases—the medieval era, the post-antiquity era, the post-ancient era, or the pre-modern era.

In Asia and the Middle East during this time, the spread of Islam helped produce a series of caliphates which fostered the Islamic Golden Age, leading to advances in science and greater trade between those in the Asian, African, and European continents. East Asia experienced the entrenchment of the power of a unitary and Imperial China, the dynastic governance and culture of which influenced Japan, Korea and Vietnam. Religions such as Buddhism and neo-Confucianism spread in the region, while Christianity became entrenched in Europe and increasingly elsewhere. Gunpowder was developed in China during the post-classical era. The Mongol Empire conquered and controlled much of Europe and Asia, permitting more trade and cultural and intellectual exchange between the two regions.

Bahrain, officially the Kingdom of Bahrain, is an island country in West Asia. Situated on the Persian Gulf, it comprises a small archipelago of 50 natural islands and an additional 33 artificial islands, centred on Bahrain Island, which makes up around 83 percent of the country's landmass. Bahrain is situated between Qatar and the northeastern coast of Saudi Arabia, to which it is connected by the King Fahd Causeway. The population is 1,588,670 as of 2024, of whom 739,736 (46.6% of the population) are Bahraini nationals, and 848,934 are expatriates (53.4% of the population). Bahrain spans some 760 square kilometres (290 sq mi) and is the third-smallest nation in Asia after Maldives and Singapore. The capital and largest city is Manama.

The area that straddles the present-day territory of Bahrain was once the site of the ancient Dilmun civilisation. It has been famed since antiquity for its pearl fisheries, which were considered the best in the world into the 19th century. Bahrain was one of the earliest areas to be influenced by Islam, during the lifetime of Muhammad in 628. Following a period of Arab rule, Bahrain was ruled by the Portuguese Empire from 1521 until 1602, when they were expelled by Shah Abbas the Great of the Safavid Iran. In 1783, the Bani Utbah and allied tribes captured Bahrain from Nasr Al-Madhkur. It has since been ruled by the Al Khalifa royal family, with Ahmed al Fateh as Bahrain's first hakim.

The Islamization of Iran began with the Muslim conquest of Iran, when the Rashidun Caliphate annexed the Sasanian Empire. It was a long process by which Islam, though initially rejected, eventually spread among the Persians and the other Iranian peoples. Although Arabization was a common element of the early Muslim conquests, it did not have as significant of an impact in Iran as it did elsewhere, as the Iranian populace persisted in maintaining many of their pre-Islamic traditions, such as their language and culture, albeit with adaptations to conform to the nascent religion. A distinctly Iranian Muslim identity emerged in this context and later sidelined the Arabs in what is known as the Iranian Intermezzo.

Iranian society was deeply transformed by the spread of Islam, which greatly influenced the nation's cultural, scientific, and political structure; the blossoming of Persian literature, philosophy, medicine, and art became major elements of Islam in Iran. Integrating a heritage of thousands of years of civilization and being at the "crossroads of the major cultural highways" in the Near East contributed to the Iranians emerging at the forefront of the Islamic Golden Age under the Abbasid Caliphate.

The history of Islam is believed, by most historians, to have originated with Muhammad's mission in Mecca and Medina at the start of the 7th century CE, although Muslims regard this time as a return to the original faith passed down by the Abrahamic prophets, such as Adam, Noah, Abraham, Moses, David, Solomon, and Jesus, with the submission (Islām) to the will of God. According to the traditional account, the Islamic prophet Muhammad began receiving what Muslims consider to be divine revelations in 610 CE, calling for submission to the one God, preparation for the imminent Last Judgement, and charity for the poor and needy. As Muhammad's message began to attract followers (the ṣaḥāba) he also met with increasing hostility and persecution from Meccan elites. In 622 CE Muhammad migrated to the city of Yathrib (now known as Medina), where he began to unify the tribes of Arabia under Islam, returning to Mecca to take control in 630 and order the destruction of all pagan idols. By the time Muhammad died c. 11 AH (632 CE), almost all the tribes of the Arabian Peninsula had converted to Islam, but disagreement broke out over who would succeed him as leader of the Muslim community during the Rashidun Caliphate.

The early Muslim conquests were responsible for the spread of Islam. By the 8th century CE, the Umayyad Caliphate extended from al-Andalus in the west to the Indus River in the east. Polities such as those ruled by the Umayyad and Abbasid caliphates (in the Middle East and later in Spain and Southern Italy), the Fatimids, Seljuks, Ayyubids, and Mamluks were among the most influential powers in the world. Highly Persianized empires built by the Samanids, Ghaznavids, and Ghurids significantly contributed to technological and administrative developments. The Islamic Golden Age gave rise to many centers of culture and science and produced notable polymaths, astronomers, mathematicians, physicians, and philosophers during the Middle Ages. By the early 13th century, the Delhi Sultanate conquered the northern Indian subcontinent, while Turkic dynasties like the Sultanate of Rum and Artuqids conquered much of Anatolia from the Byzantine Empire throughout the 11th and 12th centuries. In the 13th and 14th centuries, destructive Mongol invasions, along with the loss of population due to the Black Death, greatly weakened the traditional centers of the Muslim world, stretching from Persia to Egypt, but saw the emergence of the Timurid Renaissance and major economic powers such as the Mali Empire in West Africa and the Bengal Sultanate in South Asia. Following the deportation and enslavement of the Muslim Moors from the Emirate of Sicily and elsewhere in southern Italy, the Islamic Iberia was gradually conquered by Christian forces during the Reconquista. Nonetheless, in the early modern period, the gunpowder empires—the Ottomans, Timurids, Mughals, and Safavids—emerged as world powers.

The 7th century is the period from 601 through 700 in accordance with the Julian calendar in the Christian Era.

The spread of Islam and the Muslim conquests began with the unification of Arabia by the Islamic prophet Muhammad starting in 622. After Muhammad's death in 632, Islam expanded beyond the Arabian Peninsula under the Rashidun Caliphate (632–661) and the Umayyad Caliphate (661–750). The Muslim conquest of Persia in the 7th century led to the downfall of the Sasanian Empire. Also conquered during the 7th century were Syria, Palestine, Armenia, Egypt, and North Africa.

In the year before the First Council of Constantinople in 381, Nicene Christianity became the official religion of the Roman Empire when Theodosius I, emperor of the East, Gratian, emperor of the West, and Gratian's junior co-ruler Valentinian II issued the Edict of Thessalonica in 380, which recognized the catholic orthodoxy, as defined by the Council of Nicea, as the Roman Empire's state religion. Historians refer to this state-sponsored church using a variety of terms: the catholic church, the orthodox church, the imperial church, the Roman church, or the Byzantine church, with some also used for wider communions extending beyond the Roman Empire. The Eastern Orthodox Church, Oriental Orthodoxy, and the Catholic Church all claim to stand in continuity from the Nicene Christian church to which Theodosius granted recognition. Political differences between the Eastern Roman Empire and the Persian Sassanid Empire led to the separation of the Church of the East in 424. A doctrinal split within the imperial church led to the independence of early Oriental Orthodoxy, while the fall of the Western Roman Empire initiated the gradual separation between Eastern and Western Christianity, culminating in the East-West schism of 1054. The Western Church evolved into the Latin Catholic Church while the Eastern Church that remained under the patronage of the Eastern empire and evolved into the Greek Orthodox Church.

Earlier in the 4th century, following the Diocletianic Persecution of 303–313 and the Donatist controversy that arose in consequence, Constantine the Great had convened councils of bishops to define the orthodoxy of the Christian faith and to expand on earlier Christian councils. A series of ecumenical councils convened by successive Roman emperors met during the 4th and the 5th centuries, but Christianity continued to suffer rifts and schisms surrounding the theological and christological doctrines of Arianism, Nestorianism, Miaphysitism, and Dyophysitism. In the 5th century, the Western Roman Empire decayed as a polity; invaders sacked Rome in 410 and in 455, and Odoacer, an Arian barbarian warlord, forced Romulus Augustus, the last nominal Western Emperor, to abdicate in 476. However, apart from the aforementioned schisms, the church as an institution persisted in communion, if not without tension, between the East and West. In the 6th century, the Byzantine armies of the Byzantine Emperor Justinian I recovered Italy and other regions of the Western Mediterranean shore. The Byzantine Empire soon lost most of these gains, but it held Rome, as part of the Exarchate of Ravenna, until 751, a period known in church history as the Byzantine Papacy. The early Muslim conquests of the 7th–9th centuries would begin a process of converting most of the then-Christian world in the Levant, Middle East, North Africa, regions of Southern Italy and the Iberian Peninsula to Islam, severely restricting the reach both of the Byzantine Empire and of its church. Christian missionary activity directed from the capital of Constantinople did not lead to a lasting expansion of the formal link between the church and the Byzantine emperor, since areas outside the Byzantine Empire's political and military control set up their own distinct churches, as in the case of Bulgaria in 919.

The Arabic script is the writing system used for Arabic (Arabic alphabet) and several other languages of Asia and Africa. It is the second-most widely used alphabetic writing system in the world (after the Latin script), the second-most widely used writing system in the world by number of countries using it, and the third-most by number of users (after the Latin and Chinese scripts).

The script was first used to write texts in Arabic, most notably the Quran, the holy book of Islam. With the religion's spread, it came to be used as the primary script for many language families, leading to the addition of new letters and other symbols. Such languages still using it are Arabic, Persian (Farsi and Dari), Urdu, Uyghur, Kurdish, Pashto, Punjabi (Shahmukhi), Sindhi, Azerbaijani (Torki in Iran), Malay (Jawi), Javanese, Sundanese, Madurese and Indonesian (Pegon), Balti, Balochi, Luri, Kashmiri, Cham (Akhar Srak), Rohingya, Somali, Mandinka, and Mooré, among others. Until the 16th century, it was also used for some Spanish texts, and—prior to the script reform in 1928—it was the writing system of Turkish.
