Islamic society was dominated by the Arab element alone and non-Arabs were subordinated to the Arabs. In fact a strong Arab empire was created which gave itself the name of an Islamic caliphate.
During this period some of the caliphs were indifferent to religious sentiments to the extent that one of them - who was the "vicegerent of the Holy Prophet" and was regarded as the protector of religion - decided without showing any respect for Islamic practices and the feelings of Muslims to construct a room above the Ka'bah so that he could have a place to enjoy and amuse himself during the annual pilgrimage.
It is even recounted of one of these caliphs that he made the Holy Quran a target for his arrow and in a poem composed to the Quran said: "On the Day of Judgment when you appear before God tell Him 'the caliph tore me.'" Naturally the Shi'ites, whose basic differences with the Sunnis were in the two questions of the Islamic caliphate and religious authority, were passing through bitter and difficult days in this dark period.
Yet in spite of the unjust and irresponsible ways of the governments of the time the asceticism and purity of the leaders of the Household of the Prophet made the Shi'ites each day ever more determined to hold on to their beliefs. Of particular importance was the tragic death of Husayn, the third Imam, which played a major role in the spread of Shi'ism, especially in regions away from the center of the caliphate, such as Iraq, the Yemen, and Persia.
This can be seen through the fact that during the period of the fifth Imam, before the end of the first Islamic century, and less than forty years after the death of Husayn, the Shi'ites took advantage of the internal differences and weaknesses in the Umayyad government and began to organize themselves, flocking to the side of the fifth Imam. People came from all Islamic countries like a flood to his door to collect hadith and to learn the Islamic sciences.
The first century had not yet ended when a few of the leaders who were influential in the government established the city of Qum in Persia and made it a Shi'ite settlement. But even then the Shi'ah continued to live for the most part in hiding and followed their religious life secretly without external manifestations.
Several times the descendants of the Prophet (who are called in Persian sadat-i 'alawi) rebelled against the injustice of the government, but each time they were defeated and usually lost their lives.
