I declare war often, in my last finished game, as the Aztecs, i went totally insane.
First, in the early part of the game, i launched a war against france to the north of me to take the pyramids from him, winning easily (why should Louis have all the government civics?).
Then i had a war against Greece and France, in the middle ages with musketman and knights, which was entirely the fault of Alexander and his preemptive tyrannical paranoia. I assume he didn't like how my culture was encroaching on his cities. Louis allied with him for revenge i assume, but i ended up taking 3 of each of their cities, including Paris, which was chock full of valuable trinkets.
The third war was my doing, because when i took over Paris, despite how culturally significant it was, it was squeezed down to one square, and people were revolting
mad:
). So yet again, i had to smash that wig-wearing moron, in order to secure breathing room for my imperial prize. However, France called upon the Incans, who were more technologically advanced than i was. On top of that they also shared a border with me on the southern end, thus leading to a two front conflict. It was a tough war, with much pillaging, but yet again it was worth it, because in the end i decimated both of their armies and took 2 of each of their cities.
Afterwards i rise up to become the undisputed superpower, with a 6 million man army. In the modern age i launch a war with Russia (even though they ended up taking NONE of the spoils, somewhat akin to the Iraq war "coalition" in todays world
) to carve up the remnants of the Incan and French empires. Even though the war only lasted 3 turns, I went from controlling 48% to 68% of the globe, therefore cementing my victory.
hehehe, war is fun. I will launch it for whatever reason.
