What is major difference between SHIA and SUNNI Muslims?

I bear witness that "both are muslim sects". I bear witness that "Shia Islam holds that Muhammad's family, the Ahl al-Bayt ("the People of the House"), and certain individuals among his descendants, who are known as Imams, have special spiritual and political authority over the community. Shia Muslims further believe that Ali, Muhammad's cousin and son-in-law, was the first of these Imams and was the rightful successor to Muhammad and thus reject the legitimacy of the first three caliphs."

I bear witness that "Sunni branch of Islam accepts the first four caliphs as rightful successors of Muhammad and accepts hadiths narrated by the companions". Peace. More.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
