[Anyone who read this before, please notice I have come back and bolded quite a bit more of the text; earlier I sent it before I was done because I had to log off prematurely].
This is from the Catholic Encyclopedia - a less than friendly witness just to demonstrate my intention of avoiding hagiography. A note says it was entered in 1910, which is probably why they call Islam "Mohammedanism", but they give a more recent additional source ... ask me if you want that one. Bolds will be mine :
I. THE FOUNDER
Mohammed, "the Praised One", the prophet of Islam and the founder of Mohammedanism, was born at Mecca (20 August?) A.D. 570. Arabia was then torn by warring factions. The tribe of Fihr, or Quarish, to which Mohammed belonged, had established itself in the south of Hijas (Hedjaz), near Mecca, which was, even then, the principal religious and commercial centre of Arabia.
The power of the tribe was continually increasing; they had become the masters and the acknowledged guardians of the sacred Kaaba, within the town of Mecca - then visited in annual pilgrimage by the heathen Arabs with their offerings and tributes - and had thereby gained such preeminence that it was comparatively easy for Mohammed to inaugurate his religious reform and his political campaign, which ended with the conquest of all Arabia and the fusion of the numerous Arab tribes into one nation, with one religion, one code, and one sanctuary. (See ARABIA, Christianity in Arabia.)
Mohammed's father was Abdallah, of the family of Hashim, who died soon after his son's birth. At the age of six the boy lost his mother and was thereafter taken care of by his uncle Abu-Talib. He spent his early life as a shepherd and an attendant of caravans, and at the age of twenty-five married a rich widow, Khadeejah, fifteen years his senior. She bore him six children, all of whom died very young except Fatima, his beloved daughter.
On his commercial journeys to Syria and Palestine he became acquainted with Jews and Christians, and acquired an imperfect knowledge of their religion and traditions. He was a man of retiring disposition, addicted to prayer and fasting, and was subject to epileptic fits. In his fortieth year (A.D. 612), he claimed to have received a call from the Angel Gabriel, and thus began his active career as the prophet of Allah and the apostle of Arabia. His converts were about forty in all, including his wife, his daughter, his father-in-law Abu Bakr, his adopted son Ali Omar, and his slave Zayd. By his preaching and his attack on heathenism, Mohammed provoked persecution which drove him from Mecca to Medina in 622, the year of the Hejira (Flight) and the beginning of the Mohammedan Era. At Medina he was recognized as the prophet of God, and his followers increased. He took the field against his enemies, conquered several Arabian, Jewish, and Christian tribes, entered Mecca in triumph in 630, demolished the idols of the Kaaba, became master of Arabia, and finally united all the tribes under one emblem and one religion. In 632 he made his last pilgrimage to Mecca at the head of forty thousand followers, and soon after his return died of a violent fever in the sixty-third year of his age, the eleventh of the Hejira, and the year 633 of the Christian era.
The sources of Mohammed's biography are numerous, but on the whole untrustworthy, being crowded with fictitious details, legends, and stories. None of his biographies were compiled during his lifetime, and the earliest was written a century and a half after his death. The Koran is perhaps the only reliable source for the leading events in his career. His earliest and chief biographers are Ibn Ishaq (A.H. 151=A.D. 768), Wakidi (207=822), Ibn Hisham (213=828), Ibn Sa'd (230=845), Tirmidhi (279=892), Tabari (310-929), the "Lives of the Companions of Mohammed", the numerous Koranic commentators [especially Tabari, quoted above, Zamakhshari 538=1144), and Baidawi (691=1292)], the "Musnad", or collection of traditions of Ahmad ibn Hanbal (241=855), the collections of Bokhari (256=870), the "Isabah", or "Dictionary of Persons who knew Mohammed", by Ibn Hajar, etc. All these collections and biographies are based on the so-called Hadiths, or "traditions", the historical value of which is more than doubtful.
These traditions, in fact, represent a gradual, and more or less artificial, legendary development, rather than supplementary historical information. According to them, Mohammed was simple in his habits, but most careful of his personal appearance. He loved perfumes and hated strong drink. Of a highly nervous temperament, he shrank from bodily pain. Though gifted with great powers of imagination, he was taciturn. He was affectionate and magnanimous, pious and austere in the practice of his religion, brave, zealous, and above reproach in his personal and family conduct. Palgrave, however, wisely remarks that "the ideals of Arab virtue were first conceived and then attributed to him". Nevertheless, with every allowance for exaggeration, Mohammed is shown by his life and deeds to have been a man of dauntless courage, great generalship, strong patriotism, merciful by nature, and quick to forgive. And yet he was ruthless in his dealings with the Jews, when once he had ceased to hope for their submission. He approved of assassination, when it furthered his cause; however barbarous or treacherous the means, the end justified it in his eyes; and in more than one case he not only approved, but also instigated the crime.
Concerning his moral character and sincerity contradictory opinions have been expressed by scholars in the last three centuries. Many of these opinions are biased either by an extreme hatred of Islam and its founder or by an exaggerated admiration, coupled with a hatred of Christianity. ...
