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 geographic center of Saudi Arabia, accounting for about a third of the country's modern population. It is the home of the House of Saud, from which they pursued the unification of Saudi Arabia since the time of the Emirate of Diriyah.
Abdulaziz bin Abdul Rahman Al Saud, known in the West 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 flag of Saudi Arabia is entirely green except for the central portion which bears an Arabic inscription and a sword in white. The inscription is the Islamic creed, or shahada: "There is no god but Allah; Muhammad is the Messenger of Allah". The current design has been used by the government of Saudi Arabia since 15 March 1973.
The House of Saud is the ruling royal family of Saudi Arabia. It is composed of the descendants of Muhammad bin Saud, founder of the Emirate of Diriyah, known as the First Saudi state (1727–1818), and his brothers, though the ruling faction of the family is primarily led by the descendants of Abdulaziz bin Abdul Rahman, the modern founder of Saudi Arabia. It forms a subtribe of the larger prominent ancient Banu Hanifa tribe of Arabia, of which well known 7th century Arabian theologist Maslama ibn Ḥabīb originates. The most influential position of the royal family is the King of Saudi Arabia, an absolute monarch. The family in total is estimated to comprise 10,000 to 20,000 members; however, the majority of power, influence and wealth is possessed by a group of about 2,000 of them. Some estimates of the royal family's wealth measure their net worth at anywhere from as low as $500 billion to as high as $3 trillion. This figure includes the market capitalization of Saudi Aramco, the state oil and gas company, and its vast assets in fossil fuel reserves, making them the wealthiest family in the world and the wealthiest in recorded history.
Abdulaziz bin Muhammad Al Saud was the second ruler of the Emirate of Diriyah. He was the eldest son of Muhammad bin Saud and the son-in-law of Muhammad bin Abdul Wahhab. Abdulaziz ruled the Emirate from 1765 until 1803. He was nicknamed by his people as the savior of his time due to his fearless activities.
The Emirate of Diriyah, also known as the First Saudi State, was established in February 1727. In 1744, the emir of a Najdi town called Diriyah, Muhammad bin Saud, and the religious leader Muhammad ibn Abd al-Wahhab formed an alliance to found a socio-religious reform movement to unify the many states of the Arabian Peninsula.
The Emirate of Nejd or Imamate of Nejd was the Second Saudi State, existing between 1824 and 1891 in Nejd, the regions of Riyadh and Ha'il of what is now Saudi Arabia. Saudi rule was restored to central and eastern Arabia after the Emirate of Diriyah, the First Saudi State, having previously been brought down by the Ottoman Empire's Egypt Eyalet in the Ottoman–Wahhabi War (1811–1818).
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 Emirate of Jabal Shammar, also known as the Emirate of Haʾil or the Rashidi Emirate, was a state in the northern part of the Arabian Peninsula, including Najd, existing from the mid-nineteenth century to 1921. Jabal Shammar in English is translated as the "Mountain of the Shammar". Jabal Shammar's capital was Ha'il. It was led by the monarchy of the Rashidi dynasty. It included parts of modern-day Saudi Arabia, Iraq, and Jordan.
The Emirate of Riyadh was the first iteration of the Third Saudi State from 1902 to 1913. It was a monarchy led by the House of Saud. The state was formed after Saudi forces seized Riyadh from the control of the Emirate of Ha'il, led by the House of Rashid, during the Battle of Riyadh. It was the direct antecedent of the Emirate of Nejd and Hasa, and the earliest legal predecessor of present-day Saudi Arabia. Al-Hasa was conquered in 1913.
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.
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 on its 33rd anniversary by King Faisal bin Abdulaziz in order to replace the Royal Seating Day and was made a public holiday by King Abdullah bin Abdulaziz in 2005. Saudi National Day 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 monarch and head of state/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 supreme commander-in-chief of the Royal Saudi 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 Ministry of Education(MoE) (Arabic: وزارة التعليم), before 2003 as the Ministry of Knowledge and until 1953 as the Directorate of Knowledge, is a government ministry in Saudi Arabia that is responsible for regulating primary, secondary and higher education in the country. It was established in 1926 by King Abdulaziz ibn Saud in the Kingdom of Nejd and Hejaz. Since the amalgamations of the General Presidency for Girls' Education (GPGE) in 2002 and the Ministry of Higher Education (MOHE) in 2015, it became the sole body which supervises all schools, universities and colleges in the country.
The Declaration of theUnification of Saudi Arabia was officially announced by Prince Faisal bin Abdulaziz, the Viceroy of Hejaz 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.
Saudi Founding Day, officially the Founding Day, is a public holiday in Saudi Arabia celebrated annually on February 22 to commemorate the enthronement of Muhammad bin Saud as the emir of the oasis town of Diriyah in 1727 following the death of his father Saud al-Muqrin, the eponymous ancestor of the al-Saud family. His hereditary succession is considered as the prelude to the inception of the First Saudi State, the antecedent to the Second Saudi State and present-day Kingdom of Saudi Arabia. It was founded in 2022 on its 295th anniversary when King Salman bin Abdulaziz issued a royal decree that designated it as a legal holiday to be observed as per the Gregorian calendar. It is one of the three non-religious national holidays observed in the country, other being the Saudi National Day and Saudi Flag Day.
