France how did the state-building and expansion & religion change overtime

Answers

Answer:

Europeans established new trading posts in Africa and Asia, which proved profitable for the rulers and merchants involved in new global trade networks. Some Asian states sought to limit the disruptive economic and cultural effects of European-dominated long-distance trade by adopting restrictive or isolationist trade policies.

(e.g. Ming China, Tokugawa Shogunate)

-Driven largely by political, religious, and economic rivalries, European states established new maritime empires, including the Portuguese, Spanish, Dutch, French, and British.

-The expansion of maritime trading networks fostered the growth of states in Africa, including the Asante and the Kingdom of the Kongo, whose participation in trading networks led to an increase in their influence.

PLEASE HELP!! its due MIDNIGHT, i will give brainiest answer.

Answers

Ethically no, you’re using free labor of people who are societally at a disadvantage. It models capitalism because you’re evolving as a corporation (financial prosperity) while the men/women in prison are doing hard labor and remaining at the bottom of the barrel (class wise). Also considering that prison environments are at the bare minimum (capacity,food,cleanliness) and still receive no type of funding to reform this issues show that big corporations have no morality/compassion DESPITE what the people might have/not done.
