Did the Crusades cause civilizations in Europe to regress or renew themselves?

The European renewed their civilization after the crusade.

Explanation:

While the Crusades ultimately resulted in defeat for Europeans and a Muslim victory, many argue that they successfully extended the reach of Christianity and Western civilization. The Roman Catholic Church experienced an increase in wealth, and the power of the Pope was elevated after the Crusades ended.

The Crusades were organized by western European Christians after centuries of Muslim wars of expansion. Their primary objectives were to stop the expansion of Muslim states, to reclaim for Christianity the Holy Land in the Middle East, and to recapture territories that had formerly been Christian.
