Judaism
Around the 1st century CE, there were several small Jewish sects: the Pharisees, Sadducees, Zealots, Essenes, and Christians. After the destruction of the Second Temple in 70 CE, these sects vanished. Christianity survived, but by breaking with Judaism and becoming a separate religion; the Pharisees survived but in the form of Rabbinic Judaism (today, known simply as "Judaism"). The Sadducees rejected the divine inspiration of the Prophets and the Writings, relying only on the Torah as divinely inspired. Consequently, a number of other core tenets of the Pharisees' belief system (which became the basis for modern Judaism), were also dismissed by the Sadducees. (The Samaritans practiced a similar religion, which is traditionally considered separate from Judaism.)
Islam by country
Islam is divided into two major religious denominations: Sunni and Shi'a. Of the total Muslim population, 87–90% are Sunni and 10–13% are Shi'a. Most Shi'as (between 68% and 80%) live in mainly four countries: Iran, Azerbaijan, Bahrain and Iraq.
Today, many of the Shia sects are extinct. The major surviving Imamah-Muslim Sects are Usulism (with nearly more than 10%), Nizari Ismailism (with nearly more than 1%) and Alevism (with slightly more than 0.5% but less than 1%). The other existing groups include Zaydi Shi'a of Yemen whose population is nearly more than 0.5% of the world's Muslim population, Musta’li Ismaili (with nearly 0.1% whose Taiyabi adherents reside in Sindh and Gujarat in South Asia. There are also significant diaspora populations in Europe, North America, the Far East and East Africa), and Ibadis from the Kharijites whose population has diminished to a level below 0.15%. On the other hand, new Muslim sects like the Nation of Islam, Ahmadi Muslims (with nearly around 1%), non-denominational Muslims, Quranist Muslims and Wahhabis (with nearly around 1-2% of the world's total Muslim population) were later independently developed.
