I got Machinery from Willem as expected. Then upgraded axemen to macemen and declared on Liz again. Only managed to take two cities. Not enough units to go on and she's got knights, they are not great for city defence but quite superior in the open. I could do with a couple of pikes or war elephants, but neither were available. She would not capitulate so its just some gold in peace deal.
I double bulb Education and bribe Suleiman on Zara. Also make a couple of nice deals with KK.
Lib Printing Press in 540 AD. I expect AI to trade Nationalism later, right now it is far more important to reach Rifling ASAP, then I can go and kill some slavemongering bastards.
KK provided Banking just when I need it! Such a good boy, perhaps, I will leave him alive. Nobody trades now but him (friendly).
Another GS was born in Washington and two turns later I start GA and switch to Caste and Pacifism. Then convert to Hindu and trade PP+Liberalism to Suleiman for Nationalism+Theology and some gold.
Two turns later Suleiman has Constitution. I suppose Representation+Mercantilism could help to keep research up once war breaks out againg. Is it wise to wait? Chances that he will research Democracy next?
