Abha is located in the southern region of Asir at an elevation of 2270 meters (7448 feet) above sea level. . Abha lies on the western edge of Mount al-Hijaz, near Jabal Sawda, claimed by some to be the highest peak in Saudi Arabia.
The climate of Abha is cold and semi-arid (Köppen: BSk) and it is influenced by city's high elevation. [inaccessible source] The city's weather is generally mild throughout the year, becoming noticeably cooler during the “low-sun” season. Abha seldom sees temperatures rise above 35 °C (95.0 °F) during the course of the year. The city averages 278 millimetres (11 in) of rainfall annually, with the bulk of the precipitation occurring between February and April, with a secondary minor wet season in July and August.
The highest recorded temperature was 40 °C (104 °F) on August 25, 1983, while the lowest recorded temperature was −2 °C (28 °F) on December 29, 1983.
In 25 B.C. Aelius Gallus marched his legions south from Egypt on a 1,300-mile expedition to take control of the ancient overland trade routes between the Mediterranean and what is now Yemen and Hadhramaut. The Romans wanted control of those routes because they were desperate for money and hoped to raise some by capturing Marib, capital of Yemen, and taking control of the trade in incense - then a priceless commodity - and other valuable aromatics. As it turned out, however, the expedition was a disaster and little information about 'Asir emerged.
By 1920, however, ibn Saud, founder of Saudi Arabia, had begun to recoup the losses of the House of Sa'ud and to unify most of the Peninsula under his rule. As part of this campaign, he sent his Bedouin warriors also known as the Ikhwan to occupy 'Asir, and from then on 'Asir was controlled by the House of Sa'ud - a situation formalized in 1934 with the signing of the Treaty of Taif between Saudi Arabia and Yemen.
Even then the region was still largely unknown to the West. In 1932, St John Philby, one of the first Europeans to explore and map the Peninsula, did enter 'Asir, but as he did not publish his observations until 1952, the area remained one of the blank spots on the world's map.
Al-Magar was a prehistoric culture whose epicenter lay in modern-day southwestern Najd. Al-Magar is characterized as being one of the first civilizations in the world where widespread domestication of animals occurred, particularly the horse, during the Neolithic period. Aside from horses animals such as sheep, goats, dogs, in particular of the Saluki breed, ostriches, falcons and fish were discovered in the form of stone statues and rock engravings. Radiocarbon dating of these and other objects discovered indicate an age of about 9,000 years. The various discoveries reflect the significance of the site as an important ancient civilization and gives it significant pre-historic importance with enough proof and detailed data for re-writing the Neolithic history of the Arabian Peninsula and Saudi Arabia in particular. Al-Magar also reveals additional information about the relationship between human economic activities and inherent climate change, how hunter-gatherer societies became sedentary, how they made use of natural resources available to them, and how they set into motion the domestication of plants and animals.
In November 2017 hunting scenes showing images of most likely domesticated dogs, resembling the Canaan dog, wearing leashes were discovered in Shuwaymis, a hilly region of northwestern Saudi Arabia. These rock engravings date back more than 8000 years, making them the earliest depictions of dogs in the world.
The first "Saudi state" established in 1744 in the area around Riyadh, rapidly expanded and briefly controlled most of the present-day territory of Saudi Arabia, sacking Karbala in 1802 and capturing Mecca in 1803, but was destroyed by 1818 by the Ottoman viceroy of Egypt, Mohammed Ali Pasha. A much smaller second "Saudi state", located mainly in Nejd, was established in 1824. Throughout the rest of the 19th century, the Al Saud contested control of the interior of what was to become Saudi Arabia with another Arabian ruling family, the Al Rashid. By 1891, the Al Rashid were victorious and the Al Saud were driven into exile in Kuwait.
At the beginning of the 20th century, the Ottoman Empire continued to control or have a suzerainty over most of the peninsula. Subject to this suzerainty, Arabia was ruled by a patchwork of tribal rulers, with the Sharif of Mecca having pre-eminence and ruling the Hejaz. In 1902, Abdul Rahman's son, Abdul Aziz—later to be known as Ibn Saud—recaptured control of Riyadh bringing the Al Saud back to Nejd. Ibn Saud gained the support of the Ikhwan, a tribal army inspired by Wahhabism and led by Faisal Al-Dawish, and which had grown quickly after its foundation in 1912. With the aid of the Ikhwan, Ibn Saud captured Al-Ahsa from the Ottomans in 1913.
In 1916, with the encouragement and support of Britain (which was fighting the Ottomans in World War I), the Sharif of Mecca, Hussein bin Ali, led a pan-Arab revolt against the Ottoman Empire to create a united Arab state. Although the Arab Revolt of 1916 to 1918 failed in its objective, the Allied victory in World War I resulted in the end of Ottoman suzerainty and control in Arabia.
On 25 March 2015, Saudi Arabia, spearheading a coalition of Sunni Muslim states, started a military intervention in Yemen against the Shia Houthis and forces loyal to former President Ali Abdullah Saleh, who was deposed in the 2011 Arab Spring uprisings.
Saudi Arabia, together with Qatar and Turkey, openly supported the Army of Conquest, an umbrella group of anti-government forces fighting in the Syrian Civil War that reportedly included an al-Qaeda linked al-Nusra Front and another Salafi coalition known as Ahrar al-Sham. Saudi Arabia was also involved in the CIA-led Timber Sycamore covert operation to train and arm Syrian rebels.
Following a number of incidents during the Hajj season, the deadliest of which killed at least 2,070 pilgrim in 2015 Mina stampede, Saudi Arabia has been accused of mismanagement and focusing on increasing money revenues while neglecting pilgrims' welfare.
In March 2015, Sweden scrapped an arms deal with Saudi Arabia, marking an end to a decade-old defense agreement with the kingdom. The decision came after Swedish Foreign Minister Margot Wallstrom was blocked by the Saudis while speaking about democracy and women's rights at the Arab League in Cairo. This also led to Saudi Arabia recalling its ambassador to Sweden.
