The Monumenta Germaniae Historica (Latin for "Historical Monuments of Germany"), frequently abbreviated MGH, is a comprehensive series of carefully edited and published primary sources, both chronicle and archival, for the study of parts of Northwestern, Central and Southern European history from the end of the Roman Empire to 1500.
[1] Despite the name, the series covers important sources for the history of many countries besides Germany, since the Society for the Publication of Sources on Germanic Affairs of the Middle Ages has included documents from many other areas subjected to the influence of Germanic tribes or rulers (Britain, Czech lands, Poland, Austria, France, Low Countries, Italy, Spain, etc.).
The MGH was founded in Hanover as a private text publication society by the Prussian reformer Heinrich Friedrich Karl Freiherr vom Stein in 1819.
Many eminent medievalists from Germany and, eventually, other countries, joined in the project of searching out and comparing manuscripts and producing scholarly editions.
The motto chosen, Sanctus amor patriae dat animum ("Sacred love for the fatherland gives the spirit"), is explained as linking Romantic nationalism with professional scholarship.
