Commanderies of the Order of Saint John

The Order of Saint John (Knights of Malta, Knights Hospitaller) was organised in a system of commanderies during the high medieval to early modern periods, to some extent surviving as the organisational structure of the several descended orders that formed after the Reformation.

In the Late Middle Ages, the bulk of possessions of the order were in the Holy Roman Empire, France, Castile, Aragon and Portugal, but they extended into Poland, Hungary, southern Italy, England and Denmark, with individual outliers in Ireland, Scotland, Sweden and Greece (the main seat of the order was in Rhodes from 1310 until 1522, and in Malta from 1530 until 1798).

The largest of the langues by far was the "German" one, which included not only all of the Holy Roman Empire but also the non–German-speaking (Slavic and Hungarian) territories east of Germany.

The German (Brandenburg) branch comprises seventeen commandries in Germany, one each in Austria, Finland, France, Hungary, and Switzerland, and a global commandry with subcommandries in twelve other countries (Australia, Belgium, Canada, Colombia, Denmark, Italy, Namibia, Poland, South Africa, the United Kingdom, the United States, and Venezuela).
