THis is the guide to earth 1000 a.d. for each civ even going to contain vikings and bzantines (though last) you can play themhttp://forums.civfanatics.com/showthread.php?t=185829!this is expected to take around 2 months so all help is appreciated.I'll edit this post each time i find the strategy for each civ.Also for each one im using the default difficulty for each. All ready here we go!
Mongols
Don't attack china simply raze the iron near the first city they have with an archer and destroy their route to silk road. then settle one settler near a lake and wait for him to talk (he'll demand that city) Take all of your army (minus an archer an settler) down the silk road. Setlle the remaining settler above saladin in the silk road. Then gather all troops near the border and attack him. take the city on the silk road the one to the east of baghdad, bagdad and jeruelaum. attack jeruselum even if europes conquered it. dont garrison any keshiks in the city dont heal them either till you get to baghad. cut all routes to jeruselaum then when all keshiks healed attack have near jeruselum trade techs and get on his good side. by this time saladin will be hoping for peace give it to him but try to get musa to attack. convert to christianity and trade techs with europe. after this whip an army
an finish him off, byzantine too if you can. then you can basicly do whatever you want but dont sign open bordes with anyone and encircle europe.keep an tech imperialism with the world for as long as you can.
India
Fight saladin. he's sitting on the best land in the game and you can take it.Slaving is the only way i could get troops plus with all those recources this works really well.I found that catupults and elephants (slaved) make the best combination for attacking. By 1500 you should have all of his empire under your control but thoese 2 north african cities are no use so i didnt conquer them. you should be able to extract a pretty good tribute from saladin for peace. Also capture constantinople and the sities east of it if you can, else the europeans might use it as a conduit to attack you. you can cruise to any victory from here but i reccomend diplomatic.
France
Your in a perfect place to expand in europe. Build oracles asap to get musketeers On the second turn you should have cordoba and fight off the culture with the great artist that spawns in paris. Build up an army and attack england, preferably before redcoats arrive
after england, spain
Even though your uu is mostly crud it is a good replacement for knights. If you attack germany be ready to fight. frederick builds up a huge army usually to fight byzantine and you should take advantage of this by attacking before byzantine is destroyed.
