You can not repair your reputation.
I know that . . . now.

You can not repair your reputation.
You can trade by coastal waters before Astronomy; the risk is that the route is easily interrupted, eg. by barbarian galleys.
No, you can't make peace until the 20-turn alliance is up UNLESS your ally makes peace with the enemy first. Not only can you not make peace, you cannot destroy the last city of the enemy until the 20 turns are up without breaking the alliance. Yeah, the AI ally does that, but you can't. The AIs never seem to take much of a hit for broken agreements.i posted similar thing somewhere else ,but if I have a mil alliance with ally against someone else,can I not make peace with the enemy without ruining my rep?
No, not until the alliance is terminated...either after 20 turns, after your ally makes an early peace, or the enemy is destroyed.can you also attack the person you are allied with??
I'll let someone else answer this. I've heard it said both ways, so I'm not sure. I never do it. One thing I do know for certain...you can't do it if you have an ROP agreement with the civ you are attacking or you will get a serious rep hit.also,in general is it ok just to attack someone without declaring war first??
Tricky question to answer that....also,in general is it ok just to attack someone without declaring war first??
...You know, you might as well just play it safe and formally declare war every time. It only takes a few seconds, so why take the risk if you're not sure?
it can also be interrupted by being at war with other civilizations... in fact, I think if you are trading with rome, and carthage is between you and rome and your trade route has to go through carthaginian water, and rome declares on carthage... YOU take the rep hit. which is completely unfair, of course.
From my experience that seems to be correct. The most common offenders, barbarians, are at war with both of course.So, my current theory around water culture and trade routes is that you can trade through culture boundaries is at least one civ in the trade is at peace with the other.
