The correct answer to this open question is the following.
Hernando DeSoto’s Expedition brought disease to the Native Americans. Is there a lesson to learn about diseases that we can apply to our world today?
Yes, there is a lesson.
The first one is that nobody has the right to mess with other nations.
The second one is that people have to be conscious that every part of the world has its customs, traditions, and hygiene practices and these have to be respected.
Native American Indians and Mesoamerican Indians were very clean people. They had notorious hygiene practices. To start with, they used to take a bath daily. They used the rivers to do that.
When the white Europeans arrived, they had tremendous bad hygiene habits. They were no clean people. They did not take a shower daily. And they brought with them several diseases unknown to the Indians. That is why they were not immune to those diseases. We are talking about chickenpox, malaria, smallpox, influenza, and cholera.
Although the Crusades are popularly viewed as religiously inspired campaigns to recapture the Holy Land, students should recognize them as a result of the social and economic events in Europe between 1000 and 1200. Religious and secular leaders seeking to end the fighting among feudal lords seized upon the Crusades as a means of redirecting that aggression. Feudal knights who would not be inheriting their family properties eagerly enlisted in the Crusades as a way to win wealth or status. The idea of the pilgrimage was a powerful one, and the Crusades were basically armed pilgrimages to the Holy Land. The various Crusades ultimately failed. The sack of Constantinople was a fitting denouement to the whole concept. The interaction with the East brought to Europe not only Arabic translations of Greek texts, but also original Arabic and Iranian scientific and philosophical works.
