Question: Extract the answer to the question from the following context. Question: Which came first, the Iraqi invasion of Kuwait or the coalition commencing hostilities? Context: The Persian Gulf War was a conflict between Iraq and a coalition force of 34 nations led by the United States. The lead up to the war began with the Iraqi invasion of Kuwait in August 1990 which was met with immediate economic sanctions by the United Nations against Iraq. The coalition commenced hostilities in January 1991, resulting in a decisive victory for the U.S. led coalition forces, which drove Iraqi forces out of Kuwait with minimal coalition deaths. Despite the low death toll, over 180,000 US veterans would later be classified as "permanently disabled" according to the US Department of Veterans Affairs (see Gulf War Syndrome). The main battles were aerial and ground combat within Iraq, Kuwait and bordering areas of Saudi Arabia. Land combat did not expand outside of the immediate Iraq/Kuwait/Saudi border region, although the coalition bombed cities and strategic targets across Iraq, and Iraq fired missiles on Israeli and Saudi cities.
Answer: Iraqi invasion of Kuwait

input: Please answer the following: Extract the answer to the question from the following context. Question: Mary never engaged in certain activities, making her have? Context: Mary's complete sinlessness and concomitant exemption from any taint from the first moment of her existence was a doctrine familiar to Greek theologians of Byzantium. Beginning with St. Gregory Nazianzen, his explanation of the "purification" of Jesus and Mary at the circumcision (Luke 2:22) prompted him to consider the primary meaning of "purification" in Christology (and by extension in Mariology) to refer to a perfectly sinless nature that manifested itself in glory in a moment of grace (e.g., Jesus at his Baptism). St. Gregory Nazianzen designated Mary as "prokathartheisa (prepurified)." Gregory likely attempted to solve the riddle of the Purification of Jesus and Mary in the Temple through considering the human natures of Jesus and Mary as equally holy and therefore both purified in this manner of grace and glory. Gregory's doctrines surrounding Mary's purification were likely related to the burgeoning commemoration of the Mother of God in and around Constantinople very close to the date of Christmas. Nazianzen's title of Mary at the Annunciation as "prepurified" was subsequently adopted by all theologians interested in his Mariology to justify the Byzantine equivalent of the Immaculate Conception. This is especially apparent in the Fathers St. Sophronios of Jerusalem and St. John Damascene, who will be treated below in this article at the section on Church Fathers. About the time of Damascene, the public celebration of the "Conception of St. Ann [i.e., of the Theotokos in her womb]" was becoming popular. After this period, the "purification" of the perfect natures of Jesus and Mary would not only mean moments of grace and glory at the Incarnation and Baptism and other public Byzantine liturgical feasts, but purification was eventually associated with the feast of Mary's very conception (along with her Presentation in the Temple as a toddler) by Orthodox authors of the 2nd millennium (e.g., St. Nicholas Cabasilas and Joseph Bryennius).

Extract the answer to the question from the following context. Question: Muhammad is related to? Context: After the assassination of Uthman in 656, Ali, a member of the Quraysh tribe and the cousin and son-in-law of Muhammad, was elected as the caliph. He soon met with resistance from several factions, owing to his relative political inexperience. Ali moved his capital from Medina to Kufa. The resulting conflict, which lasted from 656 until 661, is known as the First Fitna ("civil war"). Muawiyah I, the governor of Syria, a relative of Uthman ibn al-Affan and Marwan I, wanted the culprits arrested. Marwan I manipulated everyone and created conflict. Aisha, the wife of Muhammad, and Talhah and Al-Zubayr, two of the companions of Muhammad, went to Basra to tell Ali to arrest the culprits who murdered Uthman. Marwan I and other people who wanted conflict manipulated everyone to fight. The two sides clashed at the Battle of the Camel in 656, where Ali won a decisive victory.
