only the first crusade was successful and out of nine crusades
The crusades increased trade between Europe and Asia.
Many people participated in the Crusades including the Christians and the Muslims. The Byzantines and the Muslim Turks were the most prominent participants in the Crusades.
The first four crusades were the most important. After that they mainly lost purpose.
Most of the crusades were named for either the number of the crusade or the area to which armies were marching. Some examples include the First through Ninth Crusades, the Northern Crusades and the Albigensian Crusade.
Most of the fighting of the Crusades is in Anatolia(Turkey) and the Kingdom of Jerusalem(Israel). Most of the people that came for the Crusades were from Europe.
The most important long term effect of the crusades is the increase of religious intolerance. For example, there has been a constant power struggle between the Jews, Catholics, and Muslims over the birth place of their religions; Jerusalem. Because of a lack of religious intolerance, that not only fueled but seemed to justify the fighting that went on during the crusades, after the crusades, and even in modern times.

Crusades
Most of the fighting took place in France.
Most of the battles of the Crusades took place in what is now the State of Israel and parts of the State of Palestine.
During the crusades there was many advancements, but castle building may be one of the most prominent. The dome like structure at the top of castles was created during the crusades and Edward II made many castles during that time period
The weapon of choice for the Crusaders was the broadsword.
Most of the battles during the Civil War in the West took place in Tennessee, Mississippi and Georgia.
Most European countries were involved in World War 1. In Western Europe, most of the fighting took place in Belgium and France and in Eastern Europe, Turkey and Bulgaria saw a lot of fighting.
During the 1st Jihad in the 8Th and 9Th centuries, Muslin armies overran most of the Mideast. including Jerusalem. The Crusades were launched to drive them out of the Christian Holy City of Jerusalem and other surrounding areas.
In a word: France. Unfortunately, a simple "France" or "Germany" answer is not truly applicable. Countries as we know them today were really formed after the crusades. However, if one were to venture a guess as to which modern country suffered the most casualties during the crusades it would be France. They provided the most crusaders and settled the Holy Land the heaviest.
