505 AD Theo, Music, Machinery -trade
520 AD Feudalism, Engineering, Optics -trade
I had to give Liberalism to all of them and Nationalism to Will to get this.
535 AD OR+Slavery
I wasted a turn or two building universities. No time for that here.
715 AD Free Religion -diplomatic reasons
715 AD Military Tradition
850 AD Gunpowder - started cuirrasier whipping
860AD Archery - hmm, I wanted some LBs. Monty went into war mode (against me by my estimate) and Isabella didn't like me either due to some trades with her worst enemy Hammurabi before I even met her.
At this point I was whipping cuirrassiers, aiming to attack somebody when I get ~30 of them. However as turns went on, I realized that I won't be able to conquer anybody on the continent. They were all advancing too fast, getting close to rifling. :/
1000 AD Printing Press -trade
1010 AD Astro -trade
1040 AD Guilds -trade
1090 AD Banking
1160 AD Chemistry (got 1GS for the partial bulb)
1250 AD defensive pact with Will

1255 AD Isabella DoWs, using a single galleon
I refused to pay 1600 gold in tribute and she went to war mode. I saw her coming and sunk that galleon before it landed any units. Willhem was very advanced at this point, with rifles and cavalry. Isabella still mediaval, but teching fast.
So...not much else to do but to invade the good old backward Montezuma and his Ottoman vassal.

1310 Rifling

1315 AD another barb city on that island taken, base for war operations and troop upgrades established.
