One of the things I want to do with the knowledge base is to track the history of social changes and movements: such as the spread of major religions, political movements, cultural fashions, and so on.  I have been doing some of this with the history of nations and major cities.

I decided to concentrate on the development of social change, particular changes and movements, and on the industrial revolution in particular. I’m pleased with the progress I am making, but there is still quite a bit to do with the addition of nations and cities.
