I'm not a history buff, but the general rules of ancient days are:
If you are a commoner/peasent, 6/10 you die due to hunger or sickness, your quality of life is terrible, and you have to constantly work to survive. And you get ordered around by upper ranks and can be killed without consequence. Wars are your funeral.
If you are an upper class person: your quality of life improves a little bit, at least you have food, and you can order servants to do what you want. Problem is that you have a bunch of other upper class people who want what you have, or want you to be gone. There will constantly be schemes and attacks to get your resources (including your own personal abilities if you have some), and to get rid of you so that they have less opposition..
In essence peasent suffer physically, while upper ranks suffer mentally (but most peasent suffer mentally as well and a lot more, and some lucky people live leasurly regardless of wealth)
Living in the past usually ain't fun.
