Why did lincoln say that he had no intention to “interfere with the institution of slavery”?

The Children's Crusades was a march of children. Children from southern France and northern Italy gathered together and marched for Jerusalem. The Children's Crusades eventually failed when they arrived at Genoa. Thousands had already perished on the journey, and no miracles occured at the port. Many children returned home, but others stayed. Those children were later killed in shipwrecks or sold as slaves. People believed that it was the devil's doing and that God was still responsible for all success. Later, the Europeans started another crusade with more vigor because Pope Innocent said that the children put them to shame. While they were fighting for the Holy Land, the adults slept and did nothing.
