I am looking for entries in military parish registers (“Militärmatriken”)

The Kriegsarchiv preserves the military registers of births (baptisms), marriages and deaths (“Militärmatriken”) for the period 1638–1920 in which each regiment, special branch, military hospital or other military institution constituted a parish of its own and thus kept its own registers for active military personnel and their families.

Unlike the “Landwehr” the navy too had their own registers.

From 1869 onwards, non-Catholic military chaplains were also required to keep appropriate registers.

These military registers are available online.

The separate ‘Kriegsmatriken’ in which the deaths of the First World War were recorded include military hospitals and prisoner-of-war camps. They are available online for military hospitals in Vienna and Lower Austria as well as for regiments and for conscripts of regiments which had their recruiting districts in Vienna, Lower Austria or the Pressburg/Bratislava/Pozsony area (including what is now the Austrian province of Burgenland).

There is no all-encompassing general index. Therefore you will first need to identify the regiment, hospital etc. in which the person concerned served or was treated.

Military registers which are not available online remain subject to the restrictions of the Austrian Personenstandsgesetz and can only be consulted in the reading room of the Central Archives.

This also applies to the parish registers of the 1. Österreichisches Bundesheer (1923–1938) which are likewise preserved by the Kriegsarchiv.

Military parish registers can also be found in the Hungarian War Archives (Feldsuperiorat Ofen and Budapest from 1762, registers of individual regiments and institutions) as well as in the Czech and Slovak War Archives.

Civil parish registers are available online via Matricula Online.
