It stretches from Yemen to

216-550: A few endemic plants grow here. Many species, such as the striped hyena , jackal and honey badger , have died out as a result of hunting , habitat destruction , overgrazing by livestock, off-road driving , and human encroachment on their habitat. Other species, such as the Arabian sand gazelle , have been successfully re-introduced and are protected at reserves. The desert lies mostly in Saudi Arabia and covers most of

These rare driest areas may get only 30 to 40 mm (1.6 in) of rain per year. The Arabian Desert’s sunshine duration index is very high by global standards: between 2,900 hours (66.2% of daylight hours) and 3,600 hours (82.1% of daylight hours), but typically around 3,400 hours (77.6% of daylight hours). Thus clear-sky conditions with plenty of sunshine prevail over

This area is known for its mariners, and its farmers raise garden crops, providing the local market with vegetables, fruits and fish. Olive oil, grain and livestock are produced in the eastern Kabla region. The Chiadma annually celebrate a 40-day pilgrimage,

According to NASA's Gravity Recovery and Climate Experiment (GRACE) satellite data (2003–2013) analysed in a University of California, Irvine (UCI) -led study published in Water Resources Research on 16 June 2015, the most over-stressed aquifer system in the world is the Arabian Aquifer System , upon which more than 60 million people depend for water.

Despite its spiritual importance, in political terms Arabia soon became a peripheral region of

The narrow coastal plain and isolated oases, amounting to less than 1% of the land area, are used to cultivate grains, coffee and tropical fruits . Goat, sheep, and camel husbandry is widespread elsewhere throughout the rest of the Peninsula. Some areas have a summer humid tropical monsoon climate , in particular

In antiquity, the term "Arabia" encompassed a larger area than the current term "Arabian Peninsula" and included the Arabian desert and large parts of the Syrian-Arabian desert . During the Hellenistic period , the area was known as Arabia ( Ancient Greek : Ἀραβία ). The Romans named three regions "Arabia": One of

1368-721: The Iberian Peninsula , to the Pyrenees . With Muhammad's death in 632, disagreement broke out over who would succeed him as leader of the Muslim community. Umar ibn al-Khattab , a prominent companion of Muhammad, nominated Abu Bakr , who was Muhammad's intimate friend and collaborator. Others added their support and Abu Bakr was made the first caliph . This choice was disputed by some of Muhammad's companions, who held that Ali ibn Abi Talib , his cousin and son-in-law, had been designated his successor. Abu Bakr's immediate task

1440-581: The Indian Ocean to the southeast. The peninsula plays a critical geopolitical role in the Arab world and globally due to its vast reserves of oil and natural gas .

1512-497: The Islamic world , in which the most important medieval Islamic states were based at various times in such far away cities as Damascus , Baghdad , and Cairo . However, from the 10th century (and, in fact, until the 20th century) the Hashemite Sharifs of Mecca maintained a state in the most developed part of the region, the Hejaz . Their domain originally comprised only the holy cities of Mecca and Medina but in

1584-637: The Nefud Desert dates to approximately 90,000 years ago and is the oldest human fossil discovered outside of Africa and the Levant. This indicates human migrations from Africa to Arabia occurred around this time. The Arabian Peninsula may have been the homeland of a ' Basal Eurasian ' population, which diverged from other Eurasians soon after the Out-of-Africa migration, and subsequently became isolated, until it started to mix with other populations in

1656-626: The Persian Gulf and Oman to Jordan and Iraq . It is the fourth largest desert in the world and the largest in Asia. At its center is Ar-Rub' al-Khali (The Empty Quarter) , one of the largest continuous bodies of sand in the world. It is an extension of the Sahara Desert . Gazelles , oryx , sand cats , and spiny-tailed lizards are just some of the desert-adapted species that survive in this extreme environment, which features everything from red dunes to deadly quicksand . The climate

1728-759: The Rashidun or "rightly guided" Caliphate . Under the Rashidun Caliphs, and, from 661, their Umayyad successors , the Arabs rapidly expanded the territory under Muslim control outside of Arabia. In a matter of decades Muslim armies decisively defeated the Byzantine army and destroyed the Persian Empire , conquering huge swathes of territory from the Iberian peninsula to India. The political focus of

The most prominent feature of the peninsula is desert , but in the southwest, there are mountain ranges, which receive greater rainfall than the rest of the peninsula. Harrat ash Shaam

2016-513: The Tuwayr , Shammar and Dhofar generally do not exceed 1,000 m (3,300 ft) in height. Not all mountains in the peninsula are visibly within ranges. Jebel Hafeet in particular, on the border of the UAE and Oman, measuring between 1,100 and 1,300 m (3,600 and 4,300 ft), is not within the Hajar range, but may be considered an outlier of that range. Most of the Arabian Peninsula

2088-472: The United States –led 2003 invasion of Iraq . Despite its historically sparse population, political Arabia stands out for its rapid population growth, driven by both significant inflows of migrant labor and persistently high birth rates. The population is characterized by its relative youth and a heavily skewed gender ratio favoring males. In several states, the number of South Asians surpasses that of

Arabia Felix had originally been used for the whole peninsula, and at other times only for the southern region. Because its use became limited to the south, the whole peninsula was simply called Arabia. Arabia Deserta was the entire desert region extending north from Arabia Felix to Palmyra and

Although, the Sharifs exercised at most times independent authority in the Hejaz , they were usually subject to the suzerainty of one of the major Islamic empires of the time.

There is evidence that human habitation in the Arabian Peninsula dates back to about 106,000 to 130,000 years ago. The harsh climate historically prevented much settlement in the pre-Islamic Arabian Peninsula, apart from

The fertile soils of Yemen have encouraged settlement of almost all of the land from sea level up to the mountains at 10,000 feet (3,000 m). In the higher elevations, elaborate terraces have been constructed to facilitate grain, fruit, coffee, ginger and khat cultivation. The Arabian peninsula

Acheulean tools found in Saffaqah, Riyadh Region reveal that hominins lived in the Arabian Peninsula around 188,000 years ago. Human habitation in Arabia may have occurred as early as 130,000 years ago. A fossilized Homo sapiens finger bone found at Al Wusta in

Broadly, the ranges can be grouped as follows: From the Hejaz southwards, the mountains show a steady increase in altitude westward as they get nearer to Yemen, and the highest peaks and ranges are all located in Yemen. The highest, Jabal An-Nabi Shu'ayb or Jabal Hadhur of the Haraz subrange of the Sarawat range, is 3,666 metres (12,028 ft) high. By comparison,

Two Saudi states were formed and controlled much of Arabia before Ibn Saud was even born. Ibn Saud, however, established the third Saudi state. The second major development has been the discovery of vast reserves of oil in the 1930s. Its production brought great wealth to all countries of

3528-472: The mountains of the UAE and northern Oman. The peninsula consists of: Arabia has few lakes or permanent rivers. Most areas are drained by ephemeral watercourses called wadis , which are dry except during the rainy season. Plentiful ancient aquifers exist beneath much of the peninsula, however, and where this water surfaces, oases form (e.g. Al-Hasa and Qatif , two of the world's largest oases ) and permit agriculture, especially palm trees , which allowed

Higher elevations are made temperate by their altitude, and the Arabian Sea coastline can receive cool, humid breezes in summer due to cold upwelling offshore. The peninsula has no thick forests. Desert-adapted wildlife is present throughout
