Re: The question of Bayt
^ first of all what shias believe today was not the same what shias in that time believed so the theory of imamate was formalized much later in its present form
secondly hussain b ALi did not rebel against muawiyah ?
intially as he had to keep his end of the treaty [like a honorable muslim ]even though muawiyah started violating his terms later on.By appointing yazid as his heir muawiyah had violated even the last clause of the treaty and rebellion against ummayyads had become legitimate
regarding peace treaty itself there is a book called "life of Imam Hasan al-mujtaba" by BAqir Shareef al-quraishi there various historical reports are discussed in great detail along with the motivation and background of the historians
