How did movement people, goods and ideas along the Silk road aid cultural diffusion and change societies over time?

The Silk Road was a way Europe and Eastern Asia spread their cultures and beliefs. As the biggest trading route, many cultures and beliefs were passed around. It started in China and the reason it's name is the "Silk" road is because China was trading silk and other textiles on this route. It stretches to every part of Europe, Middle East, and Eastern Asia. Now it is used to spread religion, food, clothes, music, etc. The whole continent became a melting pot because everyone was trading cultures and beliefs around.

regarding the law, the 15th amendment was specifically designed thinking in the rights of black free men.

even though ratified on february 3, 1870, the promise of the 15th amendment would not be fully applied for a long time.poll taxes and literacy tests would allow southern states disenfranchise african americans. only in 1965 the voting rights for african americans would be actually able to vote in the south.

in 1965, president johnson signed the voting rights act, which aimed to overcome legal barriers that prevented african americans from voting as it was guaranteed by the 15th amendment to the u.s. constitution.

i think it’s a i hope that right : )
