So, I don't know if this has been doscussed, but a major point of discussion at my house is the way in which each community this season is symbolic of a different period in human history.

Thus far, we have decided that Alexandria is most like modern times. It has running water and electricity. It is suburbia.

Sanctuary is alluding to the industrial age due to the heavy industrial setting. They also are using trade (by force, but still trade) to get goods instead of producing much on their own.

The Kingdom seems very renaissance to me. The lush gardens, the continuation of music and education. Ezekiel is the kind of King who wants his people to be happy and intelligent. Very enlightened in an apocalypse.

Hilltop would be reminiscent of Midieval times. Unlike Ezekiel, Gregory doesn't really care about the prople who live under him. The giant mansion makes me think of a castle while the serfs are outside trying to scrape by. This is also where we see the blacksmith, which feels very midieval to me.

Oceanside community reminds me of amazonian women. They represent the Classical Age.

Finally, the new group of Scavengers are pre-agricultural hunter gatherers. Their use of language almost seems to have decended to short, non-complex thoughts.

This is just my observations. What do you guys think?

Also I am pretty tired, so there's a good chance I'm not making any sense.

 

Valid point on Sanctuary. Perhaps its a combo of industrialism and imperialism?

 

Also, another hallmark of the industrial age was the unsafe and unfair business practices that took place, which could be indicated by the high risk that rick and co face if they don't make their quota.
