Sometime ago someone asked about software that shows changes
over time on the historical map (a moving history atlas)
the program "Millenium" shows Europe and Middle East (eastern
Mediterranean and North Africa) history from AD 1000 to the
present. It is quite detailed, and as far as I can see not
many errors. The company also sells "centennia" and a similar
map for the US, showing evolution of state and county boundaries.
