Not the best of sources, but here is some history of Miraak
Miraak History
During the period of time when http://elderscrolls.wikia.com/wiki/Dragon ruled over mortals, Miraak served as a dragon priest on the island of Solstheim. At some point before his death, he came into possession of a black book which in term lead to him in service of http://elderscrolls.wikia.com/wiki/Hermaeus_Mora, the Daedric Lord of Knowledge and Fate, who taught him a http://elderscrolls.wikia.com/wiki/Bend_Will. With this forbidden knowledge in his possession, Miraak turned on his dragon masters, using his power to devour their souls to become ever more powerful. According to http://elderscrolls.wikia.com/wiki/Frea, because of his betrayal, the dragons sought him out at his http://elderscrolls.wikia.com/wiki/Temple_of_Miraak on Solstheim and killed him for his treachery. After his death, he lived on in http://elderscrolls.wikia.com/wiki/Apocrypha, the realm of Hermaeus Mora, until the time was right for his return.

There is also a book, I forgot the name of it, that talkes about a deciever/betrayer and how Hermy grabbed him up.
Edit: The name of the book is the Guardian and the Traitor. Here is a link to it.
