The Safavid conversion of Iran to Shia Islam was a process of forced conversion that took place roughly over the 16th through 18th centuries and turned Iran (Persia), which previously had a Sunni majority population, into the spiritual bastion of Shia Islam.
Until the 16th century, Persia was mostly Sunni. At the turn of that century, the Safavid dynasty conquered much of what is now Iran and made Shiism the official religion. The conversion was accompanied by a massive crackdown on Sunnis, so that over time much of the population became Shia.
Iran is unique in the Muslim world because its population is overwhelmingly more Shia than Sunni (Shia constitute 95% of the population) and because its constitution is theocratic republic based on rule by a Shia jurist.
Regardless of what the Iranian government does, though, Shia Muslims in Sunni countries have every right to practise their faith and, if they wish, to try to convert others. It may worry the Sunni regimes but it also worries the Wahhabi/Salafi elements whose ideology has often gone unchallenged in the public discourse.
A majority of Iraqi Arabs are Shias, but Sunnis ran the show when Saddam Hussein, himself Sunni, ruled Iraq. Saddam spread a false belief, still surprisingly persistent in the country today, that Sunnis were the real majority in Iraq.
Iran's Sunni community is relatively free to practice its religion in the majority of Iran's 31 provinces. According to Article 12 of the Iranian Constitution, Sunnis are allowed to perform their religious rites and to provide the children of believers with religious education as they see fit.
As many as 4,000 people are estimated to have been killed by Shia-Sunni sectarian attacks in Pakistan between 1987–2007. And since 2008, thousands of Shia have been killed by Sunni extremists according to Human Rights Watch (HRW).
Islam is the dominant religion in Egypt (Arabic: مِصر, romanized: Miṣr) with around an estimated 90.3% of the population. Almost the entirety of Egypt's Muslims are Sunnis, with a very small minority of Shia. Islam has been recognized as the state religion since 1980.
The Islamization of Iran occurred as a result of the Muslim conquest of Persia in 633–654 AD. It was a long process by which Islam, though initially rejected, was gradually accepted by the majority of the population.
Approximately 11 percent of the population are citizens, of whom more than 85 percent are Sunni Muslims, according to media reports. The vast majority of the remainder are Shia Muslims, who are concentrated in the Emirates of Dubai and Sharjah.
According to scholar Ladan Boroumand "Iran today is witnessing the highest rate of Christianization in the world", and according to scholar Shay Khatiri of Johns Hopkins University “Islam is the fastest shrinking religion in there [Iran], while Christianity is growing the fastest”, and in 2018 "up to half a million ...
Most of the Kuwaiti population embraces Islam. Majority of the Kuwaiti Muslims are Sunnis and the rest are Shia'a. Adherents of other religions are given the complete freedom to practice their own rituals provided that provided that no prejudice may occur against Islam.
Late 18th to mid-20th century. Since the late 18th century, most of Iraq's Sunni Arab tribes converted to Shia Islam (particularly in the 19th century). During the 19th century, the Ottoman Empire instituted a policy of settling the semi-nomadic Sunni Arab tribes to create greater centralization in Iraq.
The Shia believe only a living scholar must be followed. Sunni Muslims pray five times a day, whereas Shia Muslims can combine prayers to pray three times a day. Shia prayers can often be identified by a small tablet of clay, from a holy place (often Karbala), on which they place their forehead while bowing in prayer.
