Chivalry. It's not really behavior so much as "I'm more powerful than you and I want your daughter, give me your daughter or I'll kill you", but your history teacher will want the answer chivalry, so I suggest you answer that, lol.
Germany.....?
I will tell you a little bit about what happened. At the end of WWI Germany was made to take blame for WWI. Pay reparations. Have their military cut down and weapons were non existent. This is why WWII happened the Allies disabled them so much they got angry and so the rise of Hitler.
Yep they disagreed about wether or not slavery should be legal
The first mask was made in 7000 BC. It was used primarily for rituals and ceremonies and where typically made of leather or wood. Keep in mind, these where the first masks that our modern generation has been able to find and preserve, masks could have been made earlier than this but detirriorated over time.
However, the first modern surgical masks where made in the early 1960s and replaced a more primitive method of cloth masks.
I hope I have helped! :)
