which all humans can adhere. Both are missionary religions believing that their adherents have an obligation to convert nonbelievers to that one true faith. From its origins Islam expanded by conquest and when the opportunity existed Christianity did also. The parallel concepts of “jihad” and “crusade” not only resemble each other but distinguish these two faiths from other major world religions. Islam and Christianity, along with Judaism, also have teleological views of history in contrast to the cyclical or static views prevalent in other civilizations.
The level of violent conflict between Islam and Christianity over time has been influenced by demographic growth and decline, economic developments, technological change, and intensity of religious commitment. The spread of Islam in the seventh century was accompanied by massive migrations of Arab peoples, “the scale and speed” of which were unprecedented, into the lands of the Byzantine and Sassanian empires. A few centuries later, the Crusades were in large part a product of economic growth, population expansion, and the “Clunaic revival” in eleventh-century Europe, which made it possible to mobilize large numbers of knights and peasants for the march to the Holy Land. When the First Crusade reached Constantinople, one Byzantine observer wrote, it seemed like “the entire West, including all the tribes of the barbarians living beyond the Adriatic Sea to the Pillars of Hercules, had started a mass migration and was on the march, bursting forth into Asia in a solid mass, with all its belongings.” [6] In the nineteenth century spectacular population growth again produced a European eruption, generating the largest migration in history, which flowed into Muslim as well as other lands.
A comparable mix of factors has increased the conflict between Islam and the West in the late twentieth century. First, Muslim population growth has generated large numbers of unemployed and disaffected young people who become recruits to Islamist causes, exert pressure on neighboring societies, and migrate to the West. Second, the Islamic Resurgence has given Muslims renewed confidence in the distinctive character and worth of their civilization and values compared to those of the West. Third, the West’s simultaneous efforts to universalize its values and institutions, to maintain its military and economic superiority, and to intervene in conflicts in the Muslim world generate intense resentment among Muslims. Fourth, the collapse of communism removed a common enemy of the West and Islam and left each the perceived major threat to the other. Fifth, the increasing contact between and intermingling of Muslims and Westerners stimulate in each a new sense of their own identity and how it differs from that of the other. Interaction and intermingling also exacerbate differences over the rights of the members of one civilization in a country dominated by members of the other civilization. Within both Muslim and Christian societies, tolerance for the other declined sharply in the 1980s and 1990s.
p. 212 The causes of the renewed conflict between Islam and the West thus lie in fundamental questions of power and culture. Kto? Kovo? Who is to rule? Who is to be ruled? The central issue of politics defined by Lenin is the root of the contest between Islam and the West. There is, however, the additional conflict, which Lenin would have considered meaningless, between two different versions of what is right and what is wrong and, as a consequence, who is right and who is wrong. So long as Islam remains Islam (which it will) and the West remains the West (which is more dubious), this fundamental conflict between two great civilizations and ways of life will continue to define their relations in the future even as it has defined them for the past fourteen centuries.
These relations are further roiled by a number of substantive issues on which their positions differ or conflict.
