This is from my own scenario, I'm Peru. Early in the game, like really, really early, the Brazilians declared war on me. But we made peace soon. No one gained anything from that war, except that I captured two of their workers.
Anyway, now I've just left the middle ages some while ago. As usual, India is the aggressor and they declared war on me when I wouldn't let them blackmail me. They have then joined military alliances with different civs against me, but most them haven't even discovered astronomy yet so they can't reach me. Loosers! But India is annoying, they just tried to invade Lima but I fought them off with heavy losses. Then their frigates keep bombing a city I have in the Pacific Ocean.
Then there's a huge war against Canada. I got USA and Mexico to join me, but recently the Americans made peace with the Canucks. Now I have destroyed two Canadian towns in Greenland, and have conquered Halifax and Montreal.
