In this paper we introduce a new source of data to economic history: palynological data or, in other words, information about pollen grains which are preserved in the bottom sediments of various water basins. We discuss how this data is collected and how it should be interpreted; develop new methods for aggregating this information into regional trends in agricultural output; construct an extensive dataset with a large number of pollen sites from Central Europe; and use our methods to study the economic history of Greater Poland, Lesser Poland, Bohemia, Brandenburg, and Lower Saxony since the first century AD.
