The history of Saudi Arabia as a nation state began with the emergence of the Al Saud dynasty in central Arabia in 1727 and the subsequent establishment of the Emirate of Diriyah. Pre-Islamic Arabia, the territory that constitutes modern Saudi Arabia, was the site of several ancient cultures and civilizations; the prehistory of Saudi Arabia shows some of the earliest traces of human activity in the world.
Najd is the central region of Saudi Arabia, in which about a third of the country's modern population resides. It is the home of the House of Saud, from which it pursued unification with Hejaz since the time of the Emirate of Diriyah.
Abdulaziz bin Abdul Rahman Al Saud, known in the Western world mononymously as Ibn Saud, was an Arab political and religious leader who founded Saudi Arabia – the third Saudi state – and reigned as its first king from 23 September 1932 until his death in 1953. He had ruled parts of the kingdom since 1902, having previously been Emir, Sultan, and King of Nejd, and King of Hejaz.
The national flag of Saudi Arabia is a green background with Arabic inscription and a sword in white. The inscription is the Islamic creed, or shahada: "There is no deity but God; Muhammad is the Messenger of God". The current design has been used by the government of Saudi Arabia since 15 March 1973.
The Sultanate of Nejd was the third iteration of the Third Saudi State, from 1921 to 1926. It was a monarchy led by the House of Saud, and a legal predecessor of modern-day Saudi Arabia. This version of the Third Saudi State was created when Abdul Aziz ibn Saud, Emir of Riyadh, declared himself sultan over Nejd and its dependencies. On the 2 December 1922, the Nejd signed an agreement with Kuwait defining their border with each other. The border would be a straight line along the 29th parallel. In December 1925, the Kingdom of Hejaz surrendered to the forces of Abdul Aziz ibn Saud, who was thereafter proclaimed king of Hejaz in January 1926 and merged his dominions into the Kingdom of Hejaz and Nejd.
The Unification of Saudi Arabia was a military and political campaign in which the various tribes, sheikhdoms, city-states, emirates, and kingdoms of most of the central Arabian Peninsula were conquered by the House of Saud, or Al Saud. Unification started in 1902 and continued until 1932, when the Kingdom of Saudi Arabia was proclaimed under the leadership of Abdulaziz, known in the West as Ibn Saud, creating what is sometimes referred to as the Third Saudi State, to differentiate it from the Emirate of Diriyah, the First Saudi State and the Emirate of Nejd, the Second Saudi State, also House of Saud states.
The Kingdom of Hejaz and Nejd, initially the Kingdom of Hejaz and Sultanate of Nejd, was a dual monarchy ruled by Abdulaziz following the victory of the Saudi Sultanate of Nejd over the Hashemite Kingdom of the Hejaz in 1925. It was the fourth iteration of the Third Saudi State.
The Third Saudi state is the heir to the two earlier Saudi states: the first and the second, founded by Abdul Aziz bin Abdul Rahman, who managed to capture the city of Riyadh on January 13, 1902. A long series of conflicts and conquests ultimately led to the establishment of the modern and contemporary Saudi state, the Kingdom of Saudi Arabia.
The Emirate of Nejd and Hasa was the second iteration of the Third Saudi State from 1913 to 1921. It was a monarchy led by the House of Saud. The state was formed after Saudi forces seized Al-Ahsa from the control of the Ottoman garrison, during the Conquest of al-Hasa. It was the direct antecedent of the Sultanate of Nejd, and a legal predecessor of modern-day Saudi Arabia.
The Saudi conquest of Hejaz or the Second Saudi-Hashemite War, also known as the Hejaz-Nejd War, was a campaign by Abdulaziz al-Saud of the Saudi Sultanate of Nejd to take over the Hashemite Kingdom of Hejaz in 1924–25, ending with conquest and incorporation of Hejaz into the Saudi domain.
Jordan–Saudi Arabia relations are characterized by mutual recognition and exchange of embassies.
The First Saudi–Hashemite War, also known as the First Nejd–Hejaz War or the al-Khurma dispute, took place in 1918–19 between Abdulaziz Ibn Saud of the Emirate of Nejd and Hasa and the Hashemites of the Kingdom of Hejaz.
Saudi National Day is a public holiday in Saudi Arabia celebrated annually on 23 September to commemorate the proclamation that renamed the Kingdom of Nejd and Hejaz as the Kingdom of Saudi Arabia in 1932 through a royal decree by King Abdulaziz ibn Saud. It was founded in 1965 by King Faisal bin Abdulaziz in order to replace the Royal Seating Day, but at the same time letting it retain the year count of 1930 instead of 1932. It was made a public holiday by King Abdullah bin Abdulaziz in 2005 and is one of the three non-religious holidays observed in the country, other being the Saudi Founding Day and Saudi Flag Day.
The king of Saudi Arabia, officially the King of the Kingdom of Saudi Arabia, is the head of state and head of government of the Kingdom of Saudi Arabia who holds absolute power. He is the head of the Saudi Arabian royal family, the House of Saud. The king is the commander-in-chief of the Saudi Arabian Armed Forces and the head of the Saudi national honors system. The king is called the "Custodian of the Two Holy Mosques", a title that signifies Saudi Arabia's jurisdiction over the mosques of Masjid al-Haram in Mecca and Al-Masjid an-Nabawi in Medina. The title has been used many times through the history of Islam. The first Saudi king to use the title was Faisal; however, King Khalid did not use the title after him. In 1986, King Fahd replaced "His Majesty" with the title of Custodian of the Two Holy Mosques, and it has been since used by both King Abdullah and King Salman. The king has been named the most powerful and influential Muslim and Arab leader in the world according to the Muslim 500.
The Ottoman era in the history of Arabia lasted from 1517 to 1918. The Ottoman degree of control over these lands varied over these four centuries, with the fluctuating strength or weakness of the Empire's central authority.
The Jordan–Saudi Arabia border is 731 km (454 mi) in length and runs from the Gulf of Aqaba in the south-west to the tripoint with Iraq in the north-east.
Bani Khalid Emirate or the Emirate of Al Humaid from the Bani Khalid tribe was a state that arose in the eastern region of the Arabian Peninsula in 1669 after Emir Barrak ibn Ghurayr made his capital in Al-Mubarraz, then managed to defeat the Ottoman Empire represented by Lahsa Eyalet and drove them out of the region. The Emirate of Al Humaid ended in 1796 after the defeat of Barak bin Abdul Mohsen at the hands of the First Saudi State.
The Declaration of theUnification of Saudi Arabia was officially announced by Prince Faisal bin Abdulaziz, the Viceroy of Hejaz and future monarch on behalf of King Abdulaziz ibn Saud on September 23, 1932, at 9:00 am from al-Hamidiyah Palace in Mecca. Faisal read out the Royal Decree No. 2716 issued by Abdulaziz ibn Saud on September 18, 1932, that renamed the Kingdom of Hejaz and Nejd and its annexes as the Kingdom of Saudi Arabia.
The Second Saudi-Rashidi War (1915–1918) also known as The Central Arabian Theatre of WWI took place between the British-aligned Emirate of Nejd and Hasa and the Emirate of Jabal Shammar, which was an ally of the Ottoman Empire.
