Abbasid CaliphateThe Abbasid Caliphate was the third caliphate to succeed the Islamic prophet Muhammad. It was founded by a dynasty descended from Muhammad's uncle, Abbas ibn Abd al-Muttalib (566–653 CE), from whom the dynasty takes its name. They ruled as caliphs for most of the caliphate from their capital in Baghdad in modern-day Iraq, after having overthrown the Umayyad Caliphate in the Abbasid Revolution of 750 CE (132 AH).
IslamIslam (ˈɪslɑːm; ۘالِإسْلَام, al-ʾIslām ʔɪsˈlæːm, ) is an Abrahamic monotheistic religion centered on the Quran and the teachings of Muhammad. Adherents of Islam, called Muslims, number approximately 2 billion globally and are the world's second-largest religious population after Christians. Muslims believe that Islam is the complete and universal version of a primordial faith that was revealed many times through earlier prophets such as Adam (believed to be the first man), Ibrahim, Moses, and Isa (Jesus), among others.
Sasanian EmpireThe Sasanian Empire (səˈsɑːniən,_səˈseɪniən), officially known as Eranshahr ("Land/Empire of the Iranians"), was the last Iranian empire before the early Muslim conquests of the 7th–8th centuries AD. Named after the House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).
CaliphateA caliphate or khilāfah (خِلَافَة, xi'laːfah) is an institution or public office under the leadership of an Islamic steward with the title of caliph (ˈkælɪf,_ˈkeɪ-; خَلِيفَة xæ'liː'fæh, ), a person considered a political-religious successor to the Islamic prophet Muhammad and a leader of the entire Muslim world (ummah). Historically, the caliphates were polities based on Islam which developed into multi-ethnic trans-national empires.
Byzantine EmpireThe Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fall of the Western Roman Empire in the 5th century AD and continued to exist until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in the Mediterranean world.
Rashidun CaliphateThe Rashidun Caliphate (al-Khilāfah ar-Rāšidah; 632 661) was the first caliphate to succeed the Islamic prophet Muhammad. It was ruled by the first four successive caliphs of Muhammad after his death in 632 CE (11 AH). During its existence, the empire was the most powerful economic, cultural, and military force in West Asia. The caliphate arose following Muhammad’s passing in June 632 and the subsequent debate over the succession to his leadership.
Dhimmi(ذمي , ˈðimmiː, collectively أهل الذمة / "the people of the covenant") or (معاهد) is a historical term for non-Muslims living in an Islamic state with legal protection. The word literally means "protected person", referring to the state's obligation under sharia to protect the individual's life, property, as well as freedom of religion, in exchange for loyalty to the state and payment of the jizya tax, in contrast to the zakat, or obligatory alms, paid by the Muslim subjects.
AliʿAlī ibn Abī Ṭālib (عَلِيّ بْن أَبِي طَالِب; 600 – 661 CE) was the last Caliph of the Rashidun Caliphate, the successor state to the Islamic prophet Muhammad's political dominions. He is considered by Shia Muslims to be the first Imam, the rightful religious and political successor to Muhammad. The issue of succession caused a major rift between Muslims and divided them into two major branches: Shia following an appointed hereditary leadership among Ali's descendants, and Sunni following political dynasties.
Poll taxA poll tax, also known as head tax or capitation, is a tax levied as a fixed sum on every liable individual (typically every adult), without reference to income or resources. Poll is an archaic term for "head" or "top of the head". The sense of "counting heads" is found in phrases like polling place and opinion poll. Head taxes were important sources of revenue for many governments from ancient times until the 19th century. In the United Kingdom, poll taxes were levied by the governments of John of Gaunt in the 14th century, Charles II in the 17th and Margaret Thatcher in the 20th century.
Abu BakrAbū Bakr ʿAbd Allāh ibn ʿAbī Quḥāfa (; 27 October 573 – 23 August 634) was the senior companion and was, through his daughter Aisha, a father-in-law of the Islamic prophet Muhammad, as well as the first Caliph of the Rashidun Caliphate. He is known with the honorific title al-Siddiq by Sunni Muslims. Abu Bakr was born in 573 CE to Abu Quhafa and Umm Khayr. He belonged to the tribe of Banu Taym. In the Age of Ignorance, he was a monotheist and condemned idol-worshipping. As a wealthy trader, Abu Bakr used to free slaves.
