So I'm playing Small King Quick Pangea Germany, bordering Maya, Spain and Poland, with Songhai and Siamese elsewhere. Maya settles a city in a completely defenseless position right next to me - to the north there are mountains (between the city and the cap), south the coast line, east is me, west is a city state. So I go ahead and do the natural thing when you get an iron start, produce catapults and try to take it. I was a bit worried since Maya was starting to snowball, they already had long-swordsman. But I focus fired the city and took it pretty quickly (he was helpless about it because there was no way for him to get units there in time). Now my border city Hamburg was in a great defensive position with hills and jungles, so I could rain down ranged attacks from above on my unfortunate enemies. He couldn't advance towards it at all. Some turns go by, and we sign peace. Quiet for some time, Maya really starting to snowball in terms of everything. They have field guns while I, as with the rest of the world, were still using trebuchets. Suddenly, out of nowhere, Poland, Spain and Songhai DoW me! All on the same turn. A turn after that, Maya DoW me as well. Apparently Maya bartered with them to do it (thanks to his very strong economy), as my spy informed me afterwards. He probably must've offered a deal to Siam as well, however we were on good terms. Now it isn't even the industrial era and I have units from every direction pouring into my borders as if I'm nearing the end of WW2. I'm asking because beforehand we seemed to be on good terms, he would offer me good money for my cocoa and he even offered me a DoF. It's also weird that he gets almost the whole world against me. First of all he's majorly ahead of everyone, and second by having everyone fight me at the same time it's like he doesn't even hope to get all my cities, but rather he's doing it just to give me the finger.
