It seems that I have completely forgotten some details of the history of this game, so I had to reread my own AAR to be able to reply to your questions.
What happened to Spain? He should have setted differently.
When Spain (PrimEval) settled his second city near my capital, and I settled my third city near his capital, the war was nearly inevitable. But I made an agreement with Spain to live peacefully till turn #150. This agreement included some points, that stated that Brazil should not settle any cities west from Barcelona while Spain should send a missionary to Brazil ASAP, because I badly wanted to spread the spanish religion in two of my cities.
About ten turns passed after Spain established its religion, but I didn't get a missionary from Spain. I wrote about this fact to PrimEval, but he didn't reply. So I decided that our agreement was terminated and begin planning & preparing for invasion of Spain.
In the middle of the preparation to war, I was contacted by EEE, who proposed to double DoW Spain. Certainly I liked this idea.
In the preparation phase, I used a double upgrade strategy against Spain. I positioned four archers and two spearmen near Salvador (my third city) which was close to the spanish capital and beelined Machinery. I timed the attack on Madrid with the completion of this tech, so I can assume that the attack was quite unexpected for PrimEval. He completed the research of the same tech just three turns after me. However, Madrid was attacked by four crossbows, a horseman and a pike, that was enough to kill two spanish crossbows who defended the city.
When we DoWed Spain, it had three cities: Madrid, Barcelona and Sevilla. Madrid was seized by Brazil, while Sevilla was taken by the Ottomans (EEE). I believe that EEE didn't suppose that Brazil would attack Madrid rather than Barcelona, while I didn't predict that the main goal of EEE in this war was seizure of Madrid. Madrid was a very juicy city (three world wonders and a good riverside location) then, and we didn't see any other way to divide it between us except by means of war...
Eventually I had to advance on Barcelona, which acted as a thorn on my ass, and at the same time defend Madrid from the Ottomans. The Great Wall helped me a lot.
Liked your start. I would have placed my 2nd city riverside instead it looked awful in first place. Capital was a beast he pulled everything needed to achieve victory.
Yeah, I have settled my capital between two pools of water to get some strategical advantage. Afterwards it turned out some kind of historical Constantinople, a trading and strategic hub between Black Sea and Mediterranean Sea, between Europe and the Middle East.
If i was Spain i would have clinched rush your 3rd city and landlock you
Spain settled its third city Sevilla so close to Istambul and landlocked the Ottomans. So the peace with Brazil was beneficial for Spain, because PrimEval already had EEE after him.
