About NGHM

Migration is produced, not given.

In registration systems and statistics, in institutions and in discourse, migration and the categories that order it are made rather than found. NGHM reads the historical record for the classifications that produced it.

From ‘Hidden Legacies, Untidy Endings’ – notes from the InechO conference in Florence01
Historical Migration Research

The biography of mobility, and the regimes that sort it

We study how migration is negotiated within migration regimes, between individuals and the institutions that classify them, model mobility from life-course data, and trace how organizations turn people into data.

History of Organized Violence

Knowledge, rule, and the record of violence

We analyze the social profiles of perpetrator and victim groups and the institutions behind them. Person-related mass records, among them the Osnabrück Gestapo card index, are read for what their categories did.

Digital History

The method that connects the fields

Across both fields we work with person-related historical mass data, GIS-based analysis and visualization, and public history. Historical data is treated not as a window onto the past but as the trace of the classifications that produced it.

Digital History

The Osnabrück Gestapo card index
