The Abbasids is the name given to the third Islamic caliphate in history, They are second Islamic dynasties and they are related to our prophet Mohammed. The Abbasids wanted to take Bahrain and keep Bahrain under their control bbecause of its strategic location and for its many advantages so a lot of countries try to take and keep Bahrain under their control and there was a fight between the other countries and people to take Bahrain and who will control Bahrain. (1) The Abbasids removed Baani Omaya sons from their way and and took the place, They spent on the ruling dynasty and chased their children until they killed most of them have been spared them only resorted to Andalusia, and was including Abdul Rahman bin Muawiya bin Hisham bin Abdul Malik bin Marwan ibn al-Hakam, Vastoly on the Iberian Peninsula, and remained in the heel of the year 1029C. The Abbasid kept Bahrain under their control in 750 C , and After that they The Abbasids made Bahrain and Oman under the Al Yamamah. After that in the east of Arabian Peninsula happened a movement of Qaramite which kept the east of Arabian Peninsula under the Qaramite control in 899 C , Its capital was made in Al-Ahsa. Abbasid took Awal Island from Qaramite so in 1058, The Qaramite tried to take Awal back from the Abbasid in 1066 C so this makes Abu al-Bahlul to repulsed them in a naval battle, This thing let the Arab people of Bahrain to hate the Qaramtie so their country falls in 1076 C with the help of Ayyunites and Seljuks. (2) Body: In less than a century, the Abbasid state extended from Andalusia and Marrakech to the west and east to India and China. They inherited the king of Kesseri and Caesar. They ruled these countries and places and established their armies and migrated to their tribes and mingled with them and their tenths. Many of these open lands entered Islam and learned Arabic in the language of the Koran and contacted the Arabs in housing and living. And trade and various affairs of life and married Arabs and within them intervention Shdhda until the emergence of a generation of breeders who were raised from the parents of Arabs and mothers of Arabic. The Arabs were the gentlemen, the rulers, the state and the state, and they had influence and power. They were fanatics of all Arabs, and they put the dictionaries in their place without their status. When the Abbasid state began, the loyalists raised their heads, revered their dignity, and entrusted their hands to the caliphate, and claimed that the Arabs had no preference for them; for they were the oldest civilization and the most powerful of them was power and took their stature and their influence increased and became them ministers and leaders and senior writers and the caliphs of the caliphate and labor and chocolates. Mixing them with Arabs and infiltrating the country. The policy of the Abbasids and the declaration of equality between the tribes and peoples and Arabs and the pro-distant influence. And we calculated that many scientists and writers, and even the caliphs and princes were of the Ajmiyat (3) The king of Bani Abbas was the result of many introductions and the end of a strange story and an end to the reasons that combined to eliminate the Umayyad state and put the reins of the Islamic caliphate in the hands of the Abbasids The first of these reasons is the persecution of the Umayyads by the Prophet, their displacement, their exile, their imprisonment, and the humiliation of them everywhere. (4) One of the reasons that helped the establishment of the Abbasid state was what was in the persecution of the Umayyads to the pro-general: As they taught us Arab Arab purely because they were proud of the Arabs great pride, and despise the pro-severe contempt, even they were using in their state one of them and pilgrims and their parents on Iraq ordered that the Kufa is not directed only Arab and was not followed succession one of the sons of the birthers who were born of The Arab in the army of the caliphate of the cavalry and loyal teams in the infantry and prevent the Umayyad marriage of pro-Arab women, but canceled what had previously signed such marriages .(5) The political situation in the cities of Bahrain in the Umayyad and Abbasid era: The Kingdom of Bahrain and Al Qatif have witnessed a series of events that have become in the Umayyad and Abbasid eras. Al Qatif was considered an important center for confronting events in this period because of its importance and its importance as the most important city in the whole of Bahrain. This is why we see it in many of the revolutions that took place in the Abbasid and Umayyad rulers, and it is striking to the attention of many of the leaders who led the revolutions which broke out as a result of the inevitable actions of the Umayyad and Abbasid states and the sense of the people of the country of Bahrain in this period of time, Umayyad and Abbasid and excessive attention to the status of governance and the capital and neglect the rest of the regions, including the country of Bahrain. The movement of the Kharijites, which took control of Qatif in 67 AH, one of the most important events in the region where the external Najdah bin Amer managed to control the Qatif after he equipped a large army led by himself from Yamama, and after fierce and fierce battles managed to achieve victory, And a spa. And set up Najdah Balqatif and took control of his influence and tried to track the remnants of the army of Abdul Qais. Thus, Najdah bin Amer al-Qatif chose a center for his rule and a starting point for the control of the coasts of the Arabian Gulf. Musab ibn al-Zubayr sent an army of 14,000 knights to eliminate Najdah and his companions and rid the territory of Bahrain of his control. However, the result came to the benefit of the outside after a strong battle. The army of Ben Zubayr, which was under the leadership of Abdullah bin Omair Leithi, and ended the battle defeat Abdullah bin Omair. The Kharijites established their feet in Qatif and became stronger even as they coveted control of the rest of the coastal provinces of the Arabian Gulf. They sent the armies from Kazma to Amman and Yemen, and the Kharijite leader Najdah bin Amer could go to Mecca for Hajj without any trouble, A clear picture of the geographical area in which the Kharijites were moving. And after the dispute within the ranks of the Kharijis, and ended up killing commander Najdah bin Amer, and received Abu Fadik leadership turned their capital to Guatha, and between them and the Umayyad army several battles so that Abdul Malik bin Marwan could defeat them after the order to fight Omar bin Abdullah Bin Muammar, who equipped a large army of 21 thousand fighters to eliminate them 3 and killed their commander (Abu Fadik), and hence became the territory of Bahrain Under the control of the Umayyad, which faced many objections in this region, the people of Bahrain in general and the cathedrals, especially on the border with the Umayyad rule, and they feel the sense of grievance because of the depletion of large sums of money from the region and which serve the capital and the manifestations of luxury and opulence, The uprisings followed each other and met with the most severe treatment and actions by pilgrims and others in the Umayyad and Abbasid eras. The most important of these uprisings happened in the year 79 AH under the leadership of Rayyan Nukri in Qatif, which stretched his power on it, and the governor of Bahrain, Mohammed bin Saasaa to control the situation, which made pilgrims send an army led by Yazid bin Abi Kabsha in 80 AH and fought fierce battles in Qatif ended the elimination of the rebels And the Crucifixion of the commander Rayyan infamous to spread terror and fear in the hearts of people, yet another storm is found, Dawood bin Mehrez of Abdul Qais of the people of Qatif able to control the area, and removed the crucified, and buried their bodies, but the Umayyad army was also able to quell this revolution led by Abdul Rahman bin Nu’man The Exorcist. In the year 86 AH (705 m) Masoud bin Abi Zaynab Muharbi revolution against the Bani Umayyah and managed to expel the worker of the illiteracy of the Shasha bin Abdullah bin Jaroud 4 and took control of the country, but this revolution like its predecessor was extinguished after the Umayyad worker in Yamama could equip a large army could Defeat the rebels 5. After that, there were a number of revolutions that did not calm down, which usually ended with the elimination of the rebels and the abuse of the people of the region and the use of the worst methods of violence and torture . The history of the Abbasid period was less revolutionary than the Umayyad period, and the Abbasids were not less cruel to the rebels. History reminded us of the revolutions that took place in Qatif and the country of Bahrain. , And was able to extinguish the sons of Abbas after Al-Mansour equipped an army led by the governor of Basra, where he managed to defeat the rebels and the Abbasid army brutally against children and women and took many of the Spaya to Mansour. In 1905 (805 AD), an uprising was led by Saif Bin Bakir, who managed to control Hajar. Al-Rashed directed an army to eliminate the rebellion in a place known as Ain al-Noura. Thus, the region witnessed many uprisings and revolutions against the Umayyad and Abbasid rule. They were met with extreme cruelty and brutality, and some Abbasid rulers deliberately set up wily governors over the people of the house to acquaint them with the loyalty of this region to the people of the house. That rewarded him for the poetry he had said to the people of the house and their Shiites were slandered. Mutawakil was known for his strong hatred of the people of the house. After this period, the Abbasid state was preoccupied with the emergence of a revolutionary political movement that spread from 255 to 269 AH. It was full of manifestations of terror and panic, and Iraq was its first theater by a group of African Negroes, slaves who were subjected to cruel treatment in Iraq that did not match the lowest levels. Humanity, this movement of distinctive character in Islamic and Arab history was its beginnings as some historians from the country of Bahrain and moved to Iraq, where the revolution after the defeat of their leader in Bahrain by Al-Arian. After this movement, Bahrain witnessed the largest religious political movement in Islamic history. It is a movement of a distinctive character.
