This is my first ever post here so feel free to remove it if there's anything wrong.

I'm very interested in the Three Kingdoms period of Chinese history, but find there's very little information in English about it. Can you guys help me out?

Were there famous people i.e. Bolivar-esque? What went wrong for France? Was it through a diplomatic dialogue or a revolution?

I imagine this is a hard thing to track since it's usually something that is exhibited in behavior and learning rather than physical defects. Is it possible to surmise that it was a pretty widespread problem when water wasn't reliably clean and beer/wine were the safer alternatives?

This seems like it would be a common question, but everything I found in searches talks about how the Nazis gained support within Germany. They don't explain how a nation that was impoverished following the first world war and forced to disband much of its military managed to take over Poland and France, march on the Soviet Union, AND bomb Britain.

Shouldn't they have been at a significant disadvantage? Why didn't the many countries they attacked have an easier time fending them off?

Why do we say 9/10's? Is there an actual legal basis behind this (either in modern law or historical law)?

Fashion trend as in a feature of clothing that is at least partially ornamental, and widely emulated and adopted quickly for the purposes of appearing appealing.

As a non-historian with a decidedly eurocentric worldview, I'm inclined to believe it's neck ruffs, like during Elizabethan eras.

How was their leadership structured? And what were the main ideas of their society? And how was it organized? Was there a type of hierarchy or caste system?

What size guns did rated and even unrated ships typically use during this time? Imagine the size of the shot would vary greaty between a schooner and ship of the line.

Also, why use a long gun over a carronade or vice versa?

Edit for clarification: I'd prefer the late 17th century to early 18th century, but will honestly take any info I can get.

I'm currently doing a project on the formation of the early Han dynasty, and I'm looking to find a copy of Sima Qian's histories with relation to this topic. The school library doesn't have a copy of the book, so I was curious if there was a source that had it available (like a pdf or a scanned copy). Are there any other important works of historical literature that I should be consulting? I'm looking specifically at the conflict prior to the formation of the Han, including the fall of Qin, as well as Liu Bang and Xiang Yu.

How did World War II effect daily American life?

Hey, r/askhistorians! I skimmed the popular questions and useful links but didn't see anything pertaining to this-if this question's already been answered, my apologies!

Next week I get to guest teach at my high school-as someone considering being a history teacher, this is a really cool opportunity. I'm going to be covering the Winter War of 1939 as well as a few fun little anecdotes (the story of Horace Greasely, maybe touch on some other noteworthy but usually glossed over figures like Audie Murphy, George Patton, Erwin Rommel). I also wanted to show a few WWII artifacts (mainly bayonets, Winterhilfswerk lapels, and a few old soldier's manuals) and discuss the difference between small arms technology.

Problem was, I realized I don't truly know that much. I know that the myth of the Nazis having superior technology is, well, a myth-they were superior in rocketry and the STG-44 bears special mention, but as far as I'm aware they weren't the technological masterminds that movies and books paint them to be...were they? In terms of the primary small arms of the varying forces, was there a definitive "superior" weapon? I'm aware that different weapons fit different circumstances-I guess what I'm trying to figure out is, was there/is there a commonly agreed-upon "best" weapon in terms of submachinegun, bolt-action rifle, etc. I've heard anecdotes of American soldiers salvaging Nazi firearms, but I don't know if those are just that-anecdotes.

Any help would be appreciated! I'm vaguely familiar with the weapons employed by the various forces (Thompson, Garand, Sten gun, Mosin-Nagant, etc, etc) but wasn't really sure of the nuances beyond that. Thank you!

The San Francisco Bay area was once a hub of military activity with 16 active bases. Since the Base Realignment and Closures of the 1980's and 1990's all that remains are Military Ocean Terminal Concord, Travis AFB, Moffett Federal Airfield and Parks Reserve Forces Training Area. Was there political reasons for this?

The Kingdom of Qin succeeded in unifying China and ending the Warring States Period. Since then, China existed in concept as a single nation. After the Qin fell to insurrection, China didn't fall apart, but instead stayed united under the Han, and has been a nation ever since.

Why didn't a similar thing happen to the Empire of Maurya in India? It barely lasted a half-century after the death of Asoka.
