I was in History class today and noticed on the map that Yugoslavia was not labelled as having been in the Warsaw Pact, but the nations around it were. Why was this?

According to wikipedia (sorry) Europeans gave up using slings in combat during the medieval era. Why is this?

I have heard from many sources that slings generally had better range and more success piercing armor than bows did. The are also cheaper to make and more easily carried than bows.

Why weren't they being used to kill knights?

It doesn't necessarily seem intuitive (to me at least) to keep an assortment of your personal effects folded up in a leather pouch that then goes inside your pocket, especially before business cards and credit cards existed. About when, and how did wallets become standard?

Or was it uncommon to see a man with a shaved head? Was it only popular among those in the military?

If someone wanted to be a US Senator prior to the 17th amendment how would you go about doing that? Did people campaign against one another within the legislature? If people were simply appointed did anyone ever turn down that appointment?

Say a novelist who was also a composer, a poet who was also a painter, etc.

I understand a big reason the Soviets failed to reach the moon was the poor design/performance of the N-1 rocket... but why did that matter? They were launching Soyuz missions pretty consistently, and even started work on the Salyut program.

Why couldn't they launch the lunar lander/propulsion assembly into orbit separately and then send a manned Soyuz to mate it in orbit? Then go to the moon?

As a clarification, I mean what was it like in a German or Soviet penal battalion. I'm not really sure if US or English penal battalions were raised. From my cursory internet search it seems like they were simply given suicidal missions like serving as "tramplers" in minefields or holding vulnerable positions. It just seems to me that there has to be more to it than that. Why wouldn't the men desert if they knew that they would literally be used to clear mines with their dead bodies and there was no hope of escaping service alive?

Out of all the major power involved, it is my understanding, that they were the only one to use African soldiers on the western front. I am aware of a certain amount of African Americans fighting. Was it purely due to lack of manpower in France or was it a different attitude to their colonies or something different entirely?

Iin 1940, the Soviet Union set up 4 soviet republics (Lithuanian SSR, Latvian SSR, Estonian SSR and Karelo-Finnish SSR) to integrate newly conquered territories into the USSR.

In 1945, at the end of WWII they occupied Poland, Czechoslovakia, Hungary, Romania, Bulgaria and parts of Germany and Austria. Why did they set these up as communist satellite states rather than integrating them into the USSR like they did with their previous conquests?

I understand a lot of it had to do with the conditions of the Treaty of Versailles, but on more of a societal/cultural level, how did conservative revolutionaries like Ernst Junger become so popular?

As a side question, where did they draw their inspiration from?

I didn't see anything like that in the book list.

Is there any added value to phrasing your question this way? Why not just ask the question? What am I missing and where is the value added? Not to pick on any question or poster in particular, but just drawing an example from today: "I'm a Christian peasant in the 14th century Balkans and the Ottomans have just conquered the place where I live. How will my life change?" Is there a need to phrase the question as such? Would "How did life change for 14th century Christian peasants living in the Balkans after being conquered by the Ottomans?" not be sufficient? (Again, not to pick on this one post, as there are countless that frame questions the same way)

Found a stack of WW2 era folded front pages at an estate sale. They were on a table when I found them, not sure how they were stored over the years. The ink has fared well, but the paper itself is pretty brittle.

I'd like to unfold the pages, preserve, and frame some of them. I considered putting them in a small area with a humidifier to help make them a bit more pliable. Is that a good idea? Any suggestions and getting some life back into the pages so I could safely unfold them?

Secondly, would like to do what I can to preserve them and protect against sunlight prior to framing. Any tips?
