Early Muslim conquests in the context of "Saudi Arabia"

Ancient history is a time period from the beginning of writing and recorded human history through late antiquity. The span of recorded history is roughly 5,000 years, beginning with the development of Sumerian cuneiform script. Ancient history covers all continents inhabited by humans in the period 3000 BC – AD 500, ending with the expansion of Islam in late antiquity.

The three-age system periodises ancient history into the Stone Age, the Bronze Age, and the Iron Age, with recorded history usually considered to begin with the Bronze Age. The start and end of the three ages vary between world regions. In many regions the Bronze Age is generally considered to begin a few centuries prior to 3000 BC, while the end of the Iron Age varies from the early first millennium BC in some regions to the late first millennium AD in others.

Hellenistic Judaism was a form of Judaism in classical antiquity that combined Jewish religious tradition with elements of Hellenistic culture and religion. Until the early Muslim conquests of the eastern Mediterranean, the main centers of Hellenistic Judaism were Alexandria in Egypt and Antioch in Syria (modern-day Turkey), the two main Greek urban settlements of the Middle East and North Africa, both founded in the end of the 4th century BCE in the wake of the conquests of Alexander the Great. Hellenistic Judaism also existed in Jerusalem during the Second Temple Period, where there was a conflict between Hellenizers and traditionalists.

The major literary product of the contact between Second Temple Judaism and Hellenistic culture is the Septuagint translation of the Hebrew Bible from Biblical Hebrew and Biblical Aramaic to Koine Greek, specifically, Jewish Koine Greek. Mentionable are also the philosophic and ethical treatises of Philo and the historiographical works of the other Hellenistic Jewish authors.

Late antiquity is a period of time that comes after the end of classical antiquity and stretches into the beginning of the Early Middle Ages, though the exact start and end dates are debated. Late antiquity represents a cultural sphere covering much of the Mediterranean world, including parts of Europe and the Near East.

Late antiquity was an era of massive political and religious transformation. Religiously, it marked the origins or ascendance of the three major monotheistic religions: Christianity, rabbinic Judaism, and Islam, as well as the period when both the Bible and the Quran were canonized. Politically, it marked the ends of the Western Roman Empire and the Sasanian Empire (the last Persian empire of antiquity), as well as the beginning of the Arab conquests and the formation of the Rashidun Caliphate. Meanwhile, the Byzantine Empire became a militarized and Christianized society. Late antiquity was also an era of significant cultural innovation and transformation, marked by the emergence of public architecture like the Hagia Sophia, and the emergence of late antique literature and art.

The ancient Near East was home to many cradles of civilization, spanning Mesopotamia, the Levant,, Egypt, Iran, Anatolia and the Armenian highlands, and the Arabian Peninsula. As such, the fields of ancient Near East studies and Near Eastern archaeology are one of the most prominent with regard to research in the realm of ancient history. Historically, the Near East denoted an area roughly encompassing the centre of West Asia, having been focused on the lands between Greece and Egypt in the west and Iran in the east. It therefore largely corresponds with the modern-day geopolitical concept of the Middle East.

The history of the ancient Near East begins with the rise of Sumer in the 4th millennium BC, though the date that it ends is a subject of debate among scholars; the term covers the region's developments in the Bronze Age and the Iron Age, and is variously considered to end with either the establishment of the Achaemenid Empire in the 6th century BC, the establishment of the Macedonian Empire in the 4th century BC, or the beginning of the early Muslim conquests in the 7th century AD.

Ancient warfare is war that was conducted from the beginning of recorded history to the end of the ancient period. The difference between prehistoric and ancient warfare is more organization oriented than technology oriented. The development of first city-states, and then empires, allowed warfare to change dramatically. Beginning in Mesopotamia, states produced sufficient agricultural surplus. This allowed full-time ruling elites and military commanders to emerge. While the bulk of military forces were still farmers, the society could portion off each year. Thus, organized armies developed for the first time. These new armies were able to help states grow in size and become increasingly centralized.

In Europe and the Near East, the end of antiquity is often equated with the Fall of Rome in 476 AD, the wars of the Eastern Roman Empire on its Southwestern Asian and North African borders, and the beginnings of the Muslim conquests in the 7th century. In China, it can also be seen as ending of the growing role of mounted warriors needed to counter the ever-growing threat from the north in the 5th century and the beginning of the Tang dynasty in 618 AD. In India, the ancient period ends with the decline of the Gupta Empire (6th century) and the beginning of the Muslim conquests there from the 8th century. In Japan, the ancient period is considered to end with the rise of feudalism in the Kamakura period in the 12–13th century.

The Umayyad Caliphate or Umayyad Empire (US: /uːˈmaɪæd/; Arabic: ٱلْخِلَافَة ٱلْأُمَوِيَّة, romanized: al-Khilāfa al-Umawiyya) was the second caliphate established after the death of the Islamic prophet Muhammad and was ruled by the Umayyad dynasty from 661 to 750. It succeeded the Rashidun Caliphate, of which the third caliph, Uthman ibn Affan, was also a member of the clan. The Umayyad family established dynastic, hereditary rule with Mu'awiya ibn Abi Sufyan, the long-time governor of Greater Syria, who became caliph after the end of the First Fitna in 661. After Mu'awiya's death in 680, conflicts over the succession resulted in the Second Fitna, and power was eventually claimed by Marwan ibn al-Hakam, from another branch of the clan. Syria remained the Umayyads' core power base thereafter, with Damascus as their capital.

The Umayyads continued the Muslim conquests, conquering Ifriqiya, Transoxiana, Sind, the Maghreb and Hispania (al-Andalus). At its greatest extent, the Umayyad Caliphate covered 11,100,000 km (4,300,000 sq mi), making it one of the largest empires in history in terms of area. The dynasty was toppled by the Abbasids in 750. Survivors of the dynasty established themselves in Córdoba which, in the form of an emirate and then a caliphate, became a world center of science, medicine, philosophy and invention during the Islamic Golden Age.

The terms Islamic world and Muslim world commonly refer to the Islamic community, which is also known as the Ummah. This consists of all those who adhere to the religious beliefs, politics, and laws of Islam or to societies in which Islam is practiced. In a modern geopolitical sense, these terms refer to countries in which Islam is widespread, although there are no agreed criteria for inclusion. The term Muslim-majority countries is an alternative often used for the latter sense.

The history of the Muslim world spans about 1,400 years and includes a variety of socio-political developments, as well as advances in the arts, science, medicine, philosophy, law, economics and technology during the Islamic Golden Age. Muslims look for guidance to the Quran and believe in the prophetic mission of the Islamic prophet Muhammad, but disagreements on other matters have led to the appearance of different religious schools of thought and sects within Islam. The Islamic conquests, which culminated in the Caliphate being established across three continents (Asia, Africa, and Europe), enriched the Muslim world, achieving the economic preconditions for the emergence of this institution owing to the emphasis attached to Islamic teachings. In the modern era, most of the Muslim world came under European colonial domination. The nation states that emerged in the post-colonial era have adopted a variety of political and economic models, and they have been affected by secular as well as religious trends.
