I know Genghis Khan's dead by this point but his inspiration was Attila. Attacking Hungary seems like a weird thing for his sons and grandsons to do

I've looked everywhere online to see what happend when someone died on a ship in the 1800s. Does anyone have any sources?

Additionally, how did cultures around the Yangtze influence the cultures of the north (and vice versa)?

Essentially I would like to know how new inventions impacted fighting in world war 2 especially with the Somme and the use of tanks as line breakers and wireless radio for communication and how did the two effect one another, compared to say world war 2 where these things had been tested already.

Was Russia even a thing back then?

Paul traveled around and shared the gospel of jesus,and he able to that so well cause he was a roman citizen and could travel freely. But how did he,when arriving at a province,prove he is such? How did anyone in general?

And what was that effect? Did he even have one?

I thought Prussia and Austria were rivals? Why did they become allies?

It's hard to imagine that every community was such a cultural melting pot that the accent was watered down everywhere in America.

We got things like the Eiffel tower and the Atomium from world fairs. When and why world fairs stopped being a "big thing"?

I'm specifically focusing on the Franks or the Angles/Saxons, but other Germanic tribes like the Vandals are great as well. How did they immigrate in the foreign lands? Did they immediately assimilate and change their language, culture, religion or were there struggles like the Frankish and Anglo-Saxon conquerors trying to force their culture on the people living there? What did the original inhabitants think of the Germanic invaders? All of these questions you can pretty much bundle up in one question: What was the settling of the Germanic tribes during the Völkerwanderung like? Also, are there any books that you would recommend on this subject?

Thank you a lot in advance.

Assuming it was the Rosenbergs that did it.

I'm uncertain if I should ask this here or /r/askscience. I imagine the physics of 1949 wasn't a state secret, and the Soviet Union had its own talented scientists. What specific information did the Soviets need to acquire through espionage in order to get the bomb? Was it a "how to build a bomb" instruction manual, or some secret physics equation that wasn't known to the public? How long would it have taken for them to build their own if they hadn't gotten it the way they did?

Edit: thought of a better way to frame it: did they need espionage to solve the engineering problem, or the underlying science.

A few days late! Sorry! Busy with stuff. Anyways though, vote for your favorite answer(s). We seed the thread to start it off, but feel free to post your own answers as well!

I'm currently taking a U.S. History class at my college and we are using the textbook, "Give Me Liberty!" Seagull forth edition by Eric Foner. Like any text book, it summarizes and makes claims about events that have taken place in the past, but it also does not make citations for them at all. Granted, in the preface the author notes how there have been "Innumerable historians on whose work [he has] drawn in preparing for this volume" and that "In the suggested reading list at the end of each chapter offers only a brief introduction to the vast body of historical scholarship that has influenced and informed this book." He then lists 45 professionals from around the nation that he has received comments, criticisms, and suggestions from. With that credit being given however, the question still remains: can we be certain in the claims made throughout this textbook, even though there are no citations for any of the claims? I ask this question because I have been taught the importance and necessity of citing your work when pulling information from other sources. Is there a point, however, where this rule no longer applies? Or am I missing something all together?

Thanks!

Edit: Wording

One of the things I hear about WW1 is that soldiers are not allowed to light three cigarettes at the same time because when the first cigarette is lighted, the enemy sniper notices the smoke, when the second cigarette is lit, the sniper aims his rifle and when the third cigarette is lit, the sniper pulls the trigger. Is this true?

The 7th to 10th century Arab/Muslim conquests swept through large parts of the World. Levant, Persia, North Africa, North India, Iberia, and more.

My question is, why are they all major Muslim populations except Iberia?

Reconqustita and Spanish Inquisition are an easy answers. What I mean is how did they last 800 years under Islamic influence, without overwhelmingly becoming Muslim like everyone else.

Today we have all sorts of medication, a good understanding of psychology etc, but people still look at depression poorly. So I was wondering how Romans and other ancient cultures treated depression.
