Arabia in the context of "Arabian plate"

In modern historiography, ancient Rome is the Roman civilisation from the founding of the Italian city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), the Roman Republic (509‍–‍27 BC), and the Roman Empire (27 BC – 476 AD) until the fall of the western empire.

Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula. The settlement grew into the city and polity of Rome, and came to control its neighbours through a combination of treaties and military strength. It eventually controlled the Italian Peninsula, assimilating the Greek culture of southern Italy (Magna Graecia) and the Etruscan culture, and then became the dominant power in the Mediterranean region and parts of Europe. At its height it controlled the North African coast, Egypt, Southern Europe, and most of Western Europe, the Balkans, Crimea, and much of the Middle East, including Anatolia, the Levant, and parts of Mesopotamia and Arabia. That empire was among the largest empires in the ancient world, covering around 5 million square kilometres (1.9 million square miles) in AD 117, with an estimated 50 to 90 million inhabitants, roughly 20% of the world's population at the time. The Roman state evolved from an elective monarchy to a classical republic and then to an increasingly autocratic military dictatorship during the Empire.

The Amazons (Ancient Greek: Ἀμαζόνες Amazónes, singular Ἀμαζών Amazōn; in Latin Amāzon, -ŏnis) were a people in Greek mythology, portrayed in a number of ancient epic poems and legends, such as the Labours of Heracles, the Argonautica and the Iliad. They were female warriors and hunters, known for their physical agility, strength, archery, riding skills, and the arts of combat. Their society was closed to men and they raised only their daughters, returning their sons to their fathers with whom they would only socialize briefly in order to reproduce.

Courageous and fiercely independent, the Amazons, commanded by their queen, regularly undertook extensive military expeditions into the far corners of the world, from Scythia to Thrace, Asia Minor, and the Aegean Islands, reaching as far as Arabia and Egypt. Besides military raids, the Amazons are also associated with the foundation of temples and the establishment of numerous ancient cities like Ephesos, Cyme, Smyrna, Sinope, Myrina, Magnesia, Pygela, etc.

A desert is a landscape where little precipitation occurs and, consequently, living conditions create unique biomes and ecosystems. The lack of vegetation exposes the unprotected surface of the ground to denudation. About one-third of the land surface of the Earth is arid or semi-arid. This includes much of the polar regions, where little precipitation occurs, and which are sometimes called polar deserts or "cold deserts". Deserts can be classified by the amount of precipitation that falls, by the temperature that prevails, by the causes of desertification or by their geographical location.

Deserts are formed by weathering processes as large variations in temperature between day and night strain the rocks, which consequently break into pieces. Although rain seldom occurs in deserts, there are occasional downpours that can result in flash floods. Rain falling on hot rocks can cause them to shatter, and the resulting fragments and rubble strewn over the desert floor are further eroded by the wind. This picks up particles of sand and dust, which can remain airborne for extended periods – sometimes causing the formation of sand storms or dust storms. Wind-blown sand grains striking any solid object in their path can abrade the surface. Rocks are smoothed down, and the wind sorts sand into uniform deposits. The grains end up as level sheets of sand or are piled high in billowing dunes. Other deserts are flat, stony plains where all the fine material has been blown away and the surface consists of a mosaic of smooth stones, often forming desert pavements, and little further erosion occurs. Other desert features include rock outcrops, exposed bedrock and clays once deposited by flowing water. Temporary lakes may form and salt pans may be left when waters evaporate. There may be underground water sources in the form of springs and seepages from aquifers. Where these are found, oases can occur.

The word "Saracen" (/ˈsærəsən/ SARR-ə-sən) was commonly used in medieval Europe to refer to a person who lived in or near what the ancient Romans knew as Arabia Petraea and Arabia Deserta. Its original meaning in Greek and Latin is not known with certainty. By the early medieval period, it had come to be associated with the Arabian tribes. Following the rise of Islam, which occurred in Arabia, the word's definition evolved to refer not only to Arabs, but to Muslims as well. It eventually became the standard adjective among European Christians for all people and things from the Muslim world, regardless of whether they were Arab in origin.

The oldest known source mentioning "Saracens" in association with Muslims is the Greek-language Christian tract Doctrina Jacobi, which was compiled in the Byzantine Empire amidst the Muslim conquest of the Levant. The word became particularly widespread in European societies during the Crusades, when it was used by the Roman Catholic Church and by several European Christian political and military figures.

Arabs (Arabic: عَرَب) are an ethnic group mainly inhabiting the Arab world in West Asia and North Africa. A significant Arab diaspora is present in various parts of the world. Before the spread of Arabic language in the wake of the Arab conquests, "Arab" largely referred to the Semitic inhabitants—both settled and nomadic—of the Arabian Peninsula and the Syrian Desert. In modern usage, it includes people from across the Greater Middle East that share Arabic as a native language.

Arabs have been in the Fertile Crescent for thousands of years. In the 9th century BCE, the Assyrians made written references to Arabs as inhabitants of the Levant, Mesopotamia, and Arabia. Throughout the Ancient Near East, Arabs established influential civilizations starting from 3000 BCE onwards, such as Dilmun, Gerrha, and Magan, playing a vital role in trade between Mesopotamia, and the Mediterranean. Other prominent tribes include Midian, ʿĀd, and Thamud mentioned in the Bible and Quran. Later, in 900 BCE, the Qedarites enjoyed close relations with the nearby Canaanite and Aramaean states, and their territory extended from Lower Egypt to the Southern Levant. From 1200 BCE to 110 BCE, powerful kingdoms emerged such as Saba, Lihyan, Minaean, Qataban, Hadhramaut, Awsan, and Homerite emerged in Arabia. According to the Abrahamic tradition, Arabs are descendants of Abraham through his son Ishmael.

A thalassocracy or thalattocracy, sometimes also maritime empire, is a state with primarily maritime realms, an empire at sea, or a seaborne empire. Traditional thalassocracies seldom dominate interiors, even in their home territories. Examples of this were the Phoenician states of Tyre, Sidon and Carthage; the Italian maritime republics of Venice and Genoa of the Mediterranean; the Omani Empire of Arabia; and the empires of Srivijaya and Majapahit in Maritime Southeast Asia. Thalassocracies can thus be distinguished from traditional empires, where a state's territories, though possibly linked principally or solely by the sea lanes, generally extend into mainland interiors in a tellurocracy ("land-based hegemony").

The term thalassocracy can also simply refer to naval supremacy, in either military or commercial senses. The ancient Greeks first used the word thalassocracy to describe the government of the Minoan civilization, whose power depended on its navy. Herodotus distinguished sea-power from land-power and spoke of the need to counter the Phoenician thalassocracy by developing a Greek "empire of the sea".

The Palearctic or Palaearctic is a biogeographic realm of the Earth, the largest of eight. Confined almost entirely to the Eastern Hemisphere, it stretches across Europe and Asia, north of the foothills of the Himalayas, and North Africa.

The realm consists of several bioregions: the Mediterranean Basin; North Africa; North Arabia; Western, Central, South and East Asia. The Palaearctic realm also has numerous rivers and lakes, forming several freshwater ecoregions.
