The word estate has different meanings One way the word is used is to refer to the real landed possessions of a person. The typical estate of a lord was one or more manors Another way the word is used refers to a group of people forming an important social order. We often see reference to three estates, the clergy, the nobility, and people of lesser rank.
The people of lesser rank are often referred to as commoners, but this is not technically correct, as most members of the nobility were also commoners.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
