  In the West, from the 11th century onward, some older cathedral schools became universities (see, for example, University of Oxford, University of Paris and University of Bologna). Previously, higher education had been the domain of Christian cathedral schools or monastic schools (Scholae monasticae), led by monks and nuns. Evidence of such schools dates back to the 6th century AD. These new universities expanded the curriculum to include academic programs for clerics, lawyers, civil servants, and physicians. The university is generally regarded as an institution that has its origin in the Medieval Christian setting.
  
  Accompanying the rise of the "new towns" throughout Europe, mendicant orders were founded, bringing the consecrated religious life out of the monastery and into the new urban setting. The two principal mendicant movements were the Franciscans and the Dominicans, founded by Francis of Assisi and Dominic, respectively. Both orders made significant contributions to the development of the great universities of Europe. Another new order was the Cistercians, whose large, isolated monasteries spearheaded the settlement of former wilderness areas. In this period, church building and ecclesiastical architecture reached new heights, culminating in the orders of Romanesque and Gothic architecture and the building of the great European cathedrals.
  
  Christian nationalism emerged during this era in which Christians felt the impulse to recover lands in which Christianity had historically flourished. From 1095 under the pontificate of Urban II, the First Crusade was launched. These were a series of military campaigns in the Holy Land and elsewhere, initiated in response to pleas from the Byzantine Emperor Alexios I for aid against Turkish expansion. The Crusades ultimately failed to stifle Islamic aggression and even contributed to Christian enmity with the sacking of Constantinople during the Fourth Crusade.
  
  The Christian Church experienced internal conflict between the 7th and 13th centuries that resulted in a schism between the Latin Church of Western Christianity branch, the now-Catholic Church, and an Eastern, largely Greek, branch (the Eastern Orthodox Church). The two sides disagreed on a number of administrative, liturgical and doctrinal issues, most prominently Eastern Orthodox opposition to papal supremacy. The Second Council of Lyon (1274) and the Council of Florence (1439) attempted to reunite the churches, but in both cases, the Eastern Orthodox refused to implement the decisions, and the two principal churches remain in schism to the present day. However, the Catholic Church has achieved union with various smaller eastern churches.
  
  In the thirteenth century, a new emphasis on Jesus' suffering, exemplified by the Franciscans' preaching, had the consequence of turning worshippers' attention towards Jews, on whom Christians had placed the blame for Jesus' death. Christianity's limited tolerance of Jews was not new—Augustine of Hippo said that Jews should not be allowed to enjoy the citizenship that Christians took for granted—but the growing antipathy towards Jews was a factor that led to the expulsion of Jews from England in 1290, the first of many such expulsions in Europe.
  
  Beginning around 1184, following the crusade against Cathar heresy, various institutions, broadly referred to as the Inquisition, were established with the aim of suppressing heresy and securing religious and doctrinal unity within Christianity through conversion and prosecution.
