The rule of the mongols had irrevocably changed the dynamics of existence in China.
Explanation:
Ming dynasty was founded after ousting the Mongols from their territory and as such had the massive task of rebuilding the identity of China from scratch and make it catch up with the world.
This is something they were able to achieve more or less.
This was done by the importance laid on the invigoration of trade routes by ship and also of art culture and literature.
The population had doubled in the time of the Ming rule in China despite the plague hitting the world.
In colonial America, Africans "contributed" to society by being a source of income for people who bought and sold them into slavery. They also contributed by being laborers in the southern plantations.
Women contributed to the society by being a house wives --meaning they took care of the house-- as well as cooking meals for the family and taking care of the children.
Native Americans, in the earlier days, contributed by trading with settlers and teaching them how to do things in their environment.
