The rule established by the Emir State of Draiyah in many areas was short-lived.
The vastness and harsh environment constituted a natural obstacle to the exercise of the ruling power of the Emir State of Draíye.
The Emir of Draiyah in Yemen, Hijaz, Asir, Muscat and Hadaramau regions had no power to rule.
On the other hand, the Emir State of Draiya lacked a solid social foundation, and expansion was an important condition for the existence of the Amir State of Draiya, and the plundering and sharing of spoils of war constituted a link between the Emir and the tribal groups.
Once the expansion stopped, the Bedouin tribes went their separate ways, the emir of Draiyah and the Olema of the Wahab sect could not control the vast number of tribes and regions, and the unified regime was bound to collapse.
The power of the Emir state of Draiyah caused panic among the Ottoman government, and the expanding Wahhab army threatened the stability of Syria and Iraq, the heart of the Ottoman Empire.
The Ottoman Sultan Mehmed II appointed the new governor of Egypt, Mohammed Ali, on an expedition to the Kingdom of Saudi Arabia.
Muhammad Ali's army entered Hijaz by sea and overland, occupying Yanbu, Medina and Jeddah.
Wahhab sent troops back from Mecca and Taif and Egyptian troops conquered the Hijaz region.
In the spring of Saudi Ibn.
Abdulaziz died, his son Abdullah ascended the throne, and the Saudi family lost control of Hijaz, Oman and Bahrain, and the Emirate of Draiyah was on the verge of extinction.
At the beginning of the year, the Wahhabs gathered 20,000 troops at Basal, and they were immediately defeated by Muhammad Ali's army, and the military strength of the Emir State of Draiyah was completely lost.
In the same month, Ibrahim, son of Muhammad Ali, captured Draiyashat and the emir Abdullah, surrendered, was captured, Wahab, and the Saudi family regime destroyed the Egyptians, becoming the ruler of Najd.
'Members of the Saudi family, including Abdullah, members of the Wahab family, as well as about 400 members of the Najd nobility, were exiled to Egypt, Ibrahim, and razed Draya to the ground.
The rest of the Saudi family retreated to central Najd, and the Wahhab movement turned to a low ebb.
Abdullah was executed by the Ottoman sultan in Istanbul earlier this year.
In the summer of 1819 Ibrahim left Draye and returned to Medina.
Muhammad Ali's aim was to control the two holy cities of Hijaz and the waters of the Red Sea, and Egypt's army was unable to rule the vast Arabian desert for long.
Ibrahim appointed Muhammad ibn Ishari ibn al-Muammar as ruler of Najd region, in Dharaya.
After Egypt's withdrawal, Najd fell into the chaos of the former tribal division.
A descendant of the Saudi family, Terchi.
Ibn Abdullah's power gradually rose in the Najd region to challenge the position of Muhammad ibn Mishari ibn al-Muammar.
After the capture of Dlaiyah and Riyadh, Muhammad ibn Ishari ibn al-Muammar was defeated and killed.
In the autumn of that year, Muhammad Ali's forces reoccupied Dra'eyah and Riyadh Terchi, and Egyptian troops executed large numbers of rebels in Najd.
Nante, with the support of the Sudel tribe, made a comeback and frequently harassed Najd's Egyptian army.
In the autumn of that year, the Egyptian army was forced to retreat to Hijaz Tarqi ibn Abdullah, garrisoned Riyah, and was able to control the Wahhab imams to control the Najd region, restore the power of the Saudi family, and establish Riyadh as the second Saudi state.
Following the tradition of the Emirate of Dlaiyah, the Emir of Riyadh is committed to the spread of the Wahhab faith and the expansion of its territory, mainly targeting the Persian Gulf coast.
Eliminating the scuffles between the tribes and ignoring Islamic laws in Najd, he expanded his sphere of influence through constant conquests, capturing not only the vicinity of Riyadh, but also parts of Qassem, Hassa, and Oman, and driving all Turkish and Egyptian armies out of Najd.
"By the end of the year, the entire Persian Gulf coast was subordinate to the Wahhab regime and paid tribute."
'The long period of indifference of the Saudi family during the reign of Terchi led to turmoil in the Saudi state.
The rebellion of Al-Bashari, a member of the Saudi family, was quickly defeated.
Nantel died in Riyadh as an assassination and Mishari took control of Riyadh with the support of the Wahhab family.
Soon after, Terchi's eldest son, Faisal, returned from Bahrain to Riyadh and executed Mishari to take over Saudi power.
Al-Faisal refused to pay tribute to the Ottoman sultan, and Egyptian troops entered Najd from Hijaz.
The Egyptian governor Muhammad Ali attempted to bring the entire Arabian Peninsula under his control, so he installed his puppet, Khalid ibn Al Saud, a prince of the Saudi family, to govern Najd al-Faisal after his defeat and sent to Cairo.
Abdullah ibn al-Sunaiin, another descendant of the Saud family, with the support of Wahhab troops, captured Riyadh, replacing Khalid ibn Saud as the emir of the Saudi state and driving all the remaining Egyptian troops out of Najd.
Al-Faisal returned from Egypt to Riyadh, and Abdullah ibn al-Sunai was defeated and killed, and Faisal once again became the emir of the Saudi state.
