As the other poster stated, you have to take a deeper look at the tech tree.

For instance, two events influence what buildings you can build. There's the Compass and Gunpowder events. So see what buildings are dependent on them.

For units, pay careful attention to those teeny/tiny shields. You'll see, for instance, that the Vikings unit (on the tech tree) has a shield at its base that has a red lion on a gold field. That's the shield for Denmark. So, only Denmark can build Vikings. Then there's also colors around some of the buildings (or the letters have that color) on the units tech tree. That means that only the selected religions can build that unit. (Red = Catholic, Green = Muslim, Purple = Orthodox)

So there's a lot of detail packed into the tech tree.

Hope this helps.[/QUOTE]
