WHATS THE MAIN DIFFERENCE BETWEEN SIAH AND SUNNI ?

you can refer to this thread Mathahibs (http://www.englishsabla.com/forum/showthread.php?s=&threadid=16065)

I found this in the net which could help you undertsand the history of that era, but I would like to stress that the diffrences are minor and all should be called muslims and nothing else!

..... This rift widened almost as soon as 'Ali, cousin and son-in-law of the Prophet, was chosen to be the fourth caliph. At issue, essentially, was the legitimacy of 'Ali's caliphate. 'Uthman's relatives - in particular Mu'awiyah, the powerful governor of Syria, where 'Ali's election had not been recognized - believed 'Ali's caliphate was invalid because his election had been supported by those responsible for 'Uthman's unavenged death. The conflict came to a climax in 657 at Siffin, near the Euphrates, and eventually resulted in a major division between the Sunnis or Sunnites and the Shi'is (also called Shi'ites or Shi'ah), the "Partisans" of 'Ali- a division that was to color the subsequent history of Islam.

Actually the Sunnis and the Shi'is are agreed upon almost all the essentials of Islam. Both believe in the Quran and the Prophet, both follow the same principles of religion and both observe the same rituals. However, there is one prominent difference, which is essentially political rather than religious, and concerns the choice of the caliph or successor of Muhammad.

The majority of Muslims support the elective principle which led to the choice of Abu Bakr as the first caliph. This group is known as ahl alsunnah wa-l-jama'ah, "the people of custom and community," or Sunnis, who consider the caliph to be Muhammad's successor only in his capacity as ruler of the community. The main body of the Shi'is, on the other hand, believes that the caliphate - which they call the imamate or "leadership" - is nonelective. The caliphate, they say, must remain within the family of the Prophet - with 'Ali the first valid caliph. And while Sunnis consider the caliph a guardian of the shari'ah, the religious law, the Shi'is see the imam as a trustee inheriting and interpreting the Prophet's spiritual knowledge.

After the battle of Siffin, 'Ali - whose chief strength was in Iraq, with his capital at Kufa - began to lose the support of many of his more uncompromising followers and in 661 he was murdered by a former supporter. His son Hasan was proclaimed caliph at Kufa but soon afterward deferred to Muiawiyah, who had already been proclaimed caliph in Jerusalem in the previous year and who now was recognized and accepted as caliph in all the Muslim territories - thus inaugurating the Umayyad dynasty which would rule for the next ninety years.

The division between the Sunnis and the Shi'is continued to develop, however, and was widened in 680 when 'Ali's son Husayn tried to win the caliphate from the Umayyads and, with his followers, was killed at Karbala in Iraq. His death is still mourned each year by the Shi'is.

Is this all?
