Why did the slaves brought to the Americans always originate from Africa? Why weren't other regions, such as Asia, used as a source for slaves?

I'm really interested in learning more about the so called Ming Secret police! The main issue I have been encountering is the lack of any real information/sources that are not in Chinese. Does anyone know of any English books or articles that go in depth. A quick glance on the internet only provides some general info, like on wikipedia and some questionable tourist sites. Any general insight and help would be greatly appreciated!

I was reading in a textbook for a modern Japanese history course that there is much debate among historians as to how far the United States should have gone in reforming the Japanese state. How much truth is in this and why is there so much debate about it?

I was taught that Medieval music, particularly music for religious purposes, either featured a choir or an instrument, but never vocal and choir in the same song. I remember being shown a song that had a choir and then a organ play, and that song was very revolutionary. How true is this? Was there a turning point where instrumental music and voices became popular to use in the same song?

it should have been high, considering the long voyage and danger. clarify my question. Ps:if there is no info on portuguese traders, any other will suffice

It's pretty amazing that Oxford University has been around since c. 1096 CE and is still fully operational. What other institutions/establishments (that aren't governments or churches) have been up and running for hundreds and hundreds of years?

Having recently read Iron Kingdom: The Rise and Downfall of Prussia , what I found particularly interesting was the century between Napoleon and WWI- specifically German Reunification, and the political manoeuvres used by Bismarck to achieve it.

What are some good books on this period?

Having played Crusader Kings II, you obviously have the benefit of playing continuously as the head of the dynasty therefore allowing you to have long term plans to further your family. This just got me wondering whether or not dynasties did actually meet and discuss their direction or not.

Why did Marcus Garvey's return to Africa movement lose steam, as well other ventures? And gave rise to intergrationalist/equal rights as preached by Dr. Martin Luther King

I'm writing a research paper for my senior seminar based on historians that argue which battle was the last battle of the Civil War. I was hoping to get Reddit's opinion on the matter.

If they did, what were their reasons for doing so?

I checked out the book called "Kursk: The Greatest Battle" which is on the Books and Resources list on the sub, but i saw that it only has four reviews on Amazon with one of them saying that it's only an introductory work, and the other calling into question the facts stated on it. So i was wondering if there were any other alternatives out there.

It seems like after the Western Roman Empire fell suddenly all these kingdoms speak different languages.

More specifically, Ancient Greek warfare in Sicily and Greater Greece? What would you recommend someone read if they had an interest in the subject.

And one little tidbit, who would you say is the most accomplished military leader that was from Greater Greece pre-Roman conquest, and why?

Thanks.

As far as I understand it was somewhat frowned upon to translate the Quran into any language other than Arabic.

If it was translated, when was the first translation of the Quran into Turkish and were there any conflicts over this?

If not, would people who spoke only Turkish not be able to read any verses of the Quran? Would Turkish Muslims be reliant on going to a Mosque to hear what was in the Quran, similar to Catholics who could not read Latin pre-Reformation?

This question could also be asked of peoples who did not adopt Arabic as a language but were nonetheless Muslim such as the Persians.

First time poster btw so please be nice if I have posted a stupid question :)

ANECDOTAL EVIDENCE DOES NOT TRUMP AN ENTIRE FIELD OF RESEARCH, DAD!

But seriously, is this a common problem?

Wasn't surgery seen as something a barber could do?
