Why are four days (Tuesday, Wednesday, Thursday, and Friday) named after Norse gods, but Saturday named after a Roman god, and Sunday and Monday named after the Sun and the Moon?

I was watching one of these YouTube videos where a historian reviews films and television shows that take place in historical settings. I think the guy was reviewing Vikings, and he mentioned that it was inaccurate the extent to which leather was being used as shirt or over-shirt material. He went on to briefly say leather was actually not that widely used for such purposes at the time. Is this accurate? Hoping some medievalists can way in. Thanks

Third battle of Panipat is widely believed that had wiped out Maratha supremacy in the north India most importantly in Delhi but was it a battle that decides future of India subcontinent, some believe it was a blessing for Marathas giving them important lessons but some believe it gave rise to British East India company but what is truth ?

A recurring subject of Pride and Prejudice involves the idea that well-bred English women of the early 19th century should be proficient in playing an instrument (and preferably be able to sing as well). However, despite these “accomplishments” such skills seem to only be used as entertainment at social occasions and/or as a demonstration of proper raising to potential suitors. As such, only people who ever seem to play the piano forte at social occasions are young women who are “out in society” (with one exceptional experience performance from the married Bingley sister)

This made me wonder, did any of these well-bred women ultimately become composers? If so, what kind of fall out did that cause for her and her family? If not, were there other other ways an exceptionally talented female musician would have benefited socially or otherwise from her skill after she was married? If a woman remained unmarried, were there any respectable ways she might have performed or taught other women?

Did German communists seek to immediately relinquish control over these territories or did they wish to extend their revolutionary government to the colonies?

World War II began a few months after the Spanish Civil War ended with Francisco Franco's Nationalist forces winning. He was ideologically similar to Hitler or Mussolini, but chose not to join with them in the war and kept Spain a neutral power. Why was this?

Let us stipulate that the worst case scenario for this wound, if treated with antiseptics and antibiotics, would be a scar.

Was it already widespread in the non-chinese parts of the empire?

From what I've noticed most ancient civilizations grew out from the nearest major river system. Be it the Tigris and Euphrates, the yellow river, and of course the nile. This has led to ask why did no native American tribe ever take advantage of the Mississippi River? With it dividing the continent down the middle it seems it could have yielded a major advantage to whoever controlled it.

Why does the UK and some of its former territories drive on the opposite side of the road as the rest of the world? Was there not a general agreement through history previously as to yielding on horseback that predates the automobile?

Let's say that somehow, by some miracle, the Axis has forced Britain into an unconditional surrender. I imagine that, when it came time to divvy up the country, her dominions, and the British Empire, Germany would preside over the Isles themselves while, at the very least, Italy would get most of Africa and Japan, most of Asia. But were formal plans for this ever devised? I'm especially curious as to their plans for the Isles.

Is there solid evidence/general information gathered about the life of Siddhartha Guatama? Do we know for sure that he is a real person who existed in the time period?

Super broad title, I know. I’m looking for books and sources (preferable first hand sources) on recruitment, industry, supply, and military organization during the Napoleonic era (any nation is fine).

I’m looking for detailed stuff; how were the men recruited? How did they produce weapons? How did supply lines/supply production work? How were the armies organized (companies, battalions, etc; naval stuff is welcome too, although I already have plenty of things on the Royal Navy so I’d prefer sources on other navies). Anything would be greatly appreciated, thank you.

Herodotus apparently visited a megalithic building with three thousand rooms, half underground, that he thought may have been the labyrinth. Of this building, he said

"...it is hard to believe that they are the work of men; the baffling and intricate passages from room to room and from court to court were an endless wonder to me, as we passed from a courtyard into rooms, from rooms into galleries, from galleries into more rooms and thence into yet more courtyards. The roof of every chamber, courtyard, and gallery is, like the walls, of stone. The walls are covered with carved figures, and each court is exquisitely built of white marble and surrounded by a colonnade"

Reading his words it was hard not to want to learn more about it. Apparently the location of this structure is known, but I can not find very much information to satiate my curiosity.
