Did German society still hold the beliefs of the Nazi regime after their defeat, and for how long did it last? We all know that Germany now shares almost no connection to the Nazi regime, but when did the Nazi propaganda and beliefs wear off on the German people, or has it always remained, especially in the older generations?

Before I get ahead of myself, I am more specifically asking how Radar was used in WW2 in daily use

Example: How did Operators on the ground, direct the German Nightfighters to their target? Did they know the Altitude at the time of early radar, or just the general place inside the "Radar Box" of the Operators. (Applies to British too repelling German bombers)

I've seen various shows and whatnot on Nightfighters and WW2 Radar system deployed by various nations and their effect, but nothing quite into detail how it actually worked back then and was guided to the target.

Cheers!

What defines Recorded History and how old is it?

I have always wondered how much information these high-born ladies had regards sex. I know the men were well-versed on the topic, but for an upper class woman and members of the royal family being married off for money etc, would they have known the basics of sex and what to expect on their wedding nights?

How did they justify belief in their gods? Same question for the Mayans (whose religious texts seem more widely available, so maybe more people would know).

There seems to be disagreement on even what they thought; most texts seem to agree that they believed enough in their gods and their myths in enough of a literal sense to justify sacrifice to continue the sun's cycle. Others suggest that they (I'll see if I can get a source for where I read this) mainly follow the idea of teotl, and that their gods are merely the incarnation of teotl, and are somewhat abstract. I've been trying to research this but there seems to be little information on the subject, and I can't figure out how they legitimize their claims, if they do at all.

We often hear about how WWI was a bloodbath because of inventions like the machine gun making centuries-old tactics useless, but what were the innovations in the 19th century that revolutionized warfare? What was different in the Napoleonic Wars as opposed to the American Revolution or the Crimean War or the Franco-Prussian War and the American Civil War? Did any of these wars introduce anything new and game-changing?

And why did countries lose or gain this position in the span of a century?

I mean, it was under the Portuguese who did Christianization during their conquests, right? Like Brazil. Or was it because the Dutch took over, which is why Timor is still catholic (since, if I'm not mistaken, they were what's left of the Portuguese empire? But it seems unlikely that the Indonesians went back to Islam after the Portuguese left. The Philippines was catholicized by Spain but still remained catholic even after the Americans.

More specifically, the French government between the Storming of the Bastille and Napoleon's coup d'etat.

How exactly did this government come to power after the monarchy was overthrown? Did it have power over all of France? Was it centralized at all, or was France in a period of anarchy?

There were two attempt of unification of Arab nations; United Arab Republic (Egypt, Syria) and Federation of Arab Republic (Libya, Egypt, Syria). Both of them seems like a good idea to me, considering most of these Arabic nations have border succeeded from colonialism times and they were divided by major power's politics. What made this unification difficult and failed? Why there is no attempt of unification anymore? Was this even realistic?

Polls usually do a good job of prediction outcomes, especially in modern western elections, but have polls ever been wrong, and the result of an election (disputed or otherwise) been way off what was expected?

I realize that the show is clearly fictional and sensationalized, but I'm curious as to what post-WWI organized crime would have looked like in England and whether the scale of crime and murder was anything like what the show depicts.

I haven' been able to find anything in books or the internet!
