The Crusades to the Holy Land all happened during the High Middle Ages. There were later military actions also called Crusades that happened in other places. An example was the Hussite Crusade, which happened in Central Europe during the period of 1420 to 1434.
Feudalism didn't die out completely from the Crusades. The Crusades helped it lessen a bit. This happened because nobles who joined the Crusades sold their land and freed the serfs. This reduced their power and enabled the kings to build stronger central governments.
