Idk if this is the event its asking for but: The “Red Summer” of 1919 marked the culmination of steadily growing tensions surrounding the great migration of African Americans from the rural South to the cities of the North that took place during World War I.
Transformed or changed from one form to another.
The right answer is iron.
Let me explain: During the Civil War, the Confederacy wanted to acquire modern armored ships, therefore, gaining advantage over their adversaries. Somewhere around 1861, the Confederate Congress purchased ships called 'ironclads' from overseas, and a few moths later, they started working on constructing and converting their wooden ships to ironclads, by coating the sides of their ships with iron.
The goal behind this new defense strategy was to make it more difficult for heavy artillery to pierce the ships, thus gaining a new naval advantage over the enemy.
I hope this answer helps! Have a great week :)
After the slavery was officially abolished in all of the US, the African Americans were quick to move out of the South and migrate massively toward the North. There were several factors as to why this happened. One big factor was that even though the slavery was abolished, the segregation and discrimination continued, so the opportunities in life were very limited. The South was not industrialized, while the North was heavily industrialized, thus the African Americans saw an opportunity to work in the factories instead in the fields. The atmosphere in the North was much better for them, as the majority of the people welcomed them and had no problems with them because of their skin color.
