Since ancient times, wars have been cruel, and in the case of insufficient military resources, in order to ensure that the country is not destroyed, children have to be conscripted into the army. Especially in Western European countries, children's armies have long been a strange thing.
From 1096 to 1291 AD, a religious war broke out on the Mediterranean coast, mainly a war of invasion by feudal lords and knights in Western Europe with the permission of the Roman Catholic Church against the Muslims of West Asia, and the Roman Catholic forces would have a cross on their chests, so this war was likened to the "cross against the bow moon".
At that time, the number of people participating in the war reached 100,000, including civilian troops and aristocratic troops, and the civilian army had no economic support, so they burned and plundered all the way. Soon the civilian army, which had no backup, was defeated by the noble army. The following year, the crusaders led by the nobles defeated Alexei I and entered Asia Minor, where they expelled the Byzantines from Chirizia during the 10-year War.
It is said that there was also a group of boy scouts who participated in the war at that time, and a young boy received the oracle of Jesus and asked him to form an army of children. After the boy performed some "miracles", a large number of followers joined the Children's Crusade, about 30,000 or so, and he led the army to the east.
But they had no food along the way, a large number of children broke away from the line, and many children fell ill on the road, and when they reached the sea, there were only 2,000 people left, and in order to cross the sea they listened to the words of two merchants and got on seven big boats, but the merchants did not take them to their destination, but were sold to Egypt and used as slaves
