Thats most of the history, the only other things I should add is this
-his son, Abdul-baha (servent of the glorious) was his successor, and last of the line. In his lifetime, he established the "house of justice" I think and set up the Baha'is capital in Haifa, Israel.

Now about the faith itself, the core beliefs:

We belive that their is one God, who manifests himself for each age. We belive that all prophets from Zoroaster, Abraham, Jesus, Muhammed, Krishna, Buddha, etc. were all manifestations. Baha'u'llah was the latest manifestaion and the spiritual messenger of our age. We also belive that their will be more prophets as time progresses. We do not belive in churches, or priests. Prayer exists, but is not required. The "temples" Big John was reffering to are acutally "houses of worship" which are just for reverence or meditation. Their is only really one festival and that is the one I meantioned above.

We belive in pacifism, as well as tolerance. The ultimate goal for the Baha'is is to unite the earth under one banner, one language and one faith. Their is a famous quote by Baha'u'llah, "The world is but one nation, and the people it's citizens".

The so called HQ of Baha'ism is in Haifa, Israel. Their, the Bab, Baha'u'llah, and Abdul'baha are buried as well as it is the seat of the "house of justice" and the great library.

So their you have it, I hope my informations good enough. Oh yea, its reffered to as the "Bahai religion" not "Bahai'sm"
