Watch the ground change hands. Pick a chapter and press play, or drag the years yourself. Every arrow is something a flag page in this atlas says happened: an army that came, a people who left, a state that took another.

Choose an arrow

Click any arrow or dot to read what the flag page says, and open the page it came from. Nothing is clicked yet, so start anywhere.

An arrow to a country joins the two countries' label points. An arrow to an empire or a people starts at the seat it ruled from or the country it came from. A dashed stub means the page names no second place. None of these is a route.

Record Atlas — Every place your people came from, and who holds the paper. Built in the open: the data and the code are on GitHub, and every source row says when it was last checked. A directory that lies is worse than no directory.
