Communication across the vast distances penetrated by the Arab armies are unlikely to have been as swift and continuous as the Arabic tradition suggests, but there clearly was a substantial degree of control from the centre. Commanders were appointed and dismissed on the caliphs’ orders and there is no example in the literature of a commander rebelling against his authority or defying his orders. This is in marked contrast with both the Roman and Sasanian empires, which were at different times effectively disabled by the rebellions of generals and governors against their rulers. The Muslim conquests were far from being the outpouring of an unruly horde of nomads; the campaigns were directed by a small group of able and determined men.
The political leadership of the early Islamic state was composed almost entirely of the
muhājirūn
, those members of the Quraysh in Mecca who had originally supported Muhammad: the
ansār
of Medina were largely, but not entirely, excluded from military command. It is unlikely, however, that the conquests would have been so successful without the military leadership and expertise provided by the rest of the Quraysh of Mecca. From about 628 onwards, more and more leading Qurashis pledged their allegiance to the Prophet. In return, many of them were rewarded with important positions in the new order. When the conquests began under Abū Bakr, he turned to this group to find many of his commanders. Among them was Khālid b. al-Walīd, who was sent by Abū Bakr to suppress the dissent in Yamāma in eastern Arabia and then on to lead the Muslim armies in Iraq and Syria. Another man from the same background was Amr b. al-Ās, an influential Qurashi who agreed to come over to Muhammad in 628 ‘on condition that my past sins [i.e. his resistance to Muhammad] be pardoned and that he give me an active part in affairs: and he did so’.

Amr was typical of the new elite who considered themselves to be socially superior to many of those who had been Muhammad’s earliest supporters. He had inherited an estate, famous for its grapes and raisins, near Tā’if and, in an incautious moment, he told a messenger sent by the caliph Umar that his, Amr’s, father had been dressed in a garment of silk with gold buttons while Umar’s father had carried firewood for a living.
14
Amr went on to play an important role in the conquest of Syria before leading the Muslim armies into Egypt. Perhaps the most striking example of the recruitment of old enemies into the new elite was the family of Abū Sufyān. Abū Sufyān was a rich Meccan of the old school and a dyed-in-the-wool opponent of Muhammad and his new religion. His sons were quick to see the possibilities of the new order and converted to Islam, one of them, Mu
c
āwiya, serving as one of Muhammad’s secretaries. Mu
c
āwiya and his brother Yazīd were dispatched with the early Muslim armies to Syria, where their father already owned landed estates. Yazīd became governor of the newly conquered territories before succumbing to plague, but Mu
c
āwiya survived to become first governor of Syria and then, from 661, caliph. He can also claim to be the founder of Muslim naval power in the eastern Mediterranean.
Among the towns of the Hijaz is the ancient city of Tā’if, high in the mountains near Mecca. Tā’if was a walled and fortified city surrounded by orchards and gardens, a place of retreat from the scorching heat of the Meccan summer. It was dominated by the high-status tribe of Thaqīf, who were the guardians of the town shrine, dedicated to the goddess al-Lat. Like many of the Meccans, the Thaqafis, as members of the tribe were called, pledged their allegiance to Muhammad in the last four years of his life. They were to become junior partners to the Quraysh in the Islamic project, especially important in the conquest and early administration of Iraq.
The members of this new elite were emphatically not Bedouin. They came from urban and commercial backgrounds. They prided themselves on the virtue of
hilm
- that is, self-control and political understanding. This was in marked contrast to the Bedouin, whom they considered excitable and unreliable, useful for their military skills and hardiness but needing to be to be controlled and led.
15
But the partnership, the complementarity, was the key to the success of the early Arab conquests, the result of the urban elite of the Hijaz using and directing the military energies of the Bedouin to achieve their aims.
When Muhammad died in 632 the whole future of the Islamic project hung in the balance. For a few weeks it was touch and go whether this new community would survive and expand or simply disintegrate into its feuding constituent parts. The future history of much of the world was decided by the actions of a small number of men arguing and debating in Medina. Muhammad had left no generally acknowledged heir. He had made it clear that he was the ‘seal of the Prophets’, the last in the great chain of messengers of God which had begun with Adam. It was quite unclear whether he could have any sort of successor at all. Different groups within the community began to assert their own needs. The
ansār
of Medina seem to have been happy to accept Islam as a religion but they no longer wished to accept the political authority of the Quraysh: after all, these men had come to them as refugees, had been welcomed into their city and were now lording it over them. It was particularly galling that new converts from the Quraysh, men who had vigorously opposed the Prophet when they themselves were fighting for his cause, now seemed to be in very influential positions. They met together in the shelter of the portico of one of their houses and debated, most apparently favouring the idea that the
ansār
should be independent and in control of their home town.
While the debate rumbled on and ideas were tossed around, other people were moving with speed and efficiency. Before the
ansār
had come to any firm conclusions, Umar b. al-Khattāb had taken the hand of Abū Bakr and pledged allegiance to him as
khalīfat Allh
, the deputy of God on earth.
a
After this dramatic gesture, both the Quraysh and, more reluctantly, the
ansār
felt obliged to accept Abū Bakr’s leadership. This at least is the account in the traditional Arab sources, and it has the ring of truth. It was essentially a
coup d’état
. In doing this, Umar was making a number of points. He was saying that there should be one successor to the Prophet who would lead the whole community, Quraysh and
ansār
alike. He was also saying that the leader would be chosen from the
muhājirūn
, the early converts from Mecca. Mecca would be the religious focus of the new religion, but political power was based in Medina and it was from Medina that the first two caliphs directed the great conquests.
In many ways the elderly Abū Bakr was the perfect choice. No one could dispute his loyalty to the Prophet and he shared with Alī the honour of being the first converts to the new religion. He had been the Prophet’s companion when he made the dangerous
hijra
from Mecca to Medina in 622. He also seems to have been tactful and diplomatic, but perhaps his most important quality was his knowledge of the Arab tribes of Arabia, their leaders, their interests and their conflicts. These qualities were to be extremely valuable in the crucial two years of his short reign.
Umar’s coup ensured that Abū Bakr and the Quraysh were going to control the nascent Muslim state, but there were much wider problems in the rest of Arabia. The spread of Muhammad’s influence in the peninsula had largely occurred peacefully: tribes and their leaders had wished to be associated with this new power and some of them had agreed to pay taxes to Medina. Muhammad’s death brought all this into question. Many of the leaders who had pledged allegiance felt that this had been a personal contract and that it lapsed with his death. Others felt that they should be allowed to be Muslims without paying the taxes or acknowledging the political authority of Medina. Yet others saw this as an opportunity to challenge the primacy of Medina. Among the latter were the numerous tribe of the Banū Hanīfa of Yamāma in eastern Arabia. They now asserted that they too had a Prophet, called Maslama. They boldly suggested that the peninsula should be divided into two zones of influence; the Quraysh could have one and they should have the other. Other tribes in north-east Arabia chose to follow a prophetess called Sajāh. Muhammad had shown how powerful a position a prophet could hold and how much benefit it could bring to his or her tribe. It was not surprising that others tried to follow his example. The Muslim sources refer to all these movements as the
ridda
, a term that usually means apostasy from Islam but in this context meant all types of rejection of Islam or the political authority of Medina.
The new Islamic leadership decided to take a bold, hard line on these developments. They demanded that those who had once pledged allegiance to Muhammad now owed it to his successor and the Medina regime. No one could be a Muslim unless they were prepared to pay taxes to Medina. In making this decision, they set in motion the events that were to result in the great Arab conquests: if they had decided to let other areas of Arabia go and consolidate the new religion around the shrine in Mecca, or if they had decided that it was possible for men to be Muslims without acknowledging the political authority of Medina, or if they had decided not to use military force to assert their authority, the conquests would never have occurred in the way they did.
Having made this decision, the leadership set about enforcing it with ruthless efficiency. Any one group that would not accept rule from Medina was to be brought into line, by force if necessary. The Meccan aristocrat Khālid b. al-Walīd was sent to crush the Banū Hanīfa and the other tribes of north-east Arabia and other expeditions, almost all led by Qurashis, were sent to Oman, south Arabia and Yemen. They were helped by the fact that many of the tribesmen of the Hijaz and western Arabia remained loyal to Medina and agreed to serve in the armies.
These
ridda
wars were effectively the first stage of the wider Islamic conquests. Khālid b. al-Walīd moved directly from crushing the Banū Hanīfa to supporting the Banū Shaybān in their first attacks on the Sasanian Empire in Iraq. Amr b. al-Ās was sent to bring the tribes of southern Syria into line and continued to be a leading figure in the conquest of the entire country.
The dynamics of these first conquests were significant. The Islamic state could never survive as a stable Arab polity confined to Arabia and desert Syria. The Bedouin had traditionally lived off raiding neighbouring tribes and extracting payment in various forms from settled peoples. It was a fundamental principle of early Islam, however, that Muslims should not attack each other: the
umma
was like a large and expanding tribe in the sense that all men were members of the same defensive group. If all the Arabs were now part of one big family, raiding each other was clearly out of the question.
16
The inhabitants of the settled communities were also fellow Muslims. A peaceful, Muslim Arabia would mean abandoning both of the traditional nomad ways of surviving. The alternatives were stark: either the Islamic elite were to lead the Bedouin against the world beyond Arabia and the desert margin, or the Islamic polity would simply disintegrate into its warring constituent parts and the normal rivalries and anarchy of desert life would reassert themselves once more. Once the
ridda
had been subdued and the tribes of Arabia were brought once more under the control of Medina, the leadership had no choice but to direct the frenetic military energies of the Bedouin against the Roman and Sasanian empires. The only way of avoiding an implosion was to direct the Muslims against the non-Muslim world.
The conquests started before the
ridda
was finally over, tribes being encouraged to join the Muslim cause and accept the authority of Medina in order to be allowed to participate in these campaigns. Soon there was a continuous procession of nomads to Medina wanting to be enrolled in armies and willing to accept the orders of Umar and the Islamic leadership.
They were dispatched in armies of fighting men. The early Muslim conquests were not achieved by a migration of Bedouin tribesmen with their families, tents and flocks in the way that the Saljuk Turks entered the Middle East in the eleventh century. They were achieved by fighting men under orders. Only after the conquest were the families allowed or encouraged to move from their desert camping grounds and settle in the newly conquered areas.
The numbers we are given for the forces vary wildly and are unlikely, at this early stage in Islamic history, to be very reliable. Muslim sources tell us that the combined might of the armies that conquered Syria was around 30,000 men,
17
but these seldom came together and operated for most of the time in smaller groups. The forces that conquered Iraq seem to have been significantly smaller, and the Arabic sources quote between 6,000 and 12,000 men.
18
The numbers in Egypt were smaller still: Amr’s initial force was between 3,500 and 4,000 men, though they were soon joined by 12,000 reinforcements. These numbers may be unreliable but they look realistic and are fairly consistent. This was not a horde that overwhelmed the opposition by sheer weight of numbers; indeed, at the crucial battles of Yarmūk in Syria and the Qādisiya in Iraq, it is possible that they were outnumbered by their Roman and Sasanian opponents.
