Before the Protestant Reformation, the Order was divided into seven langues or tongues. The langues were divided into great priories, some of which were further divided into priories or bailiwicks (ballei), and these were in turn divided into commanderies.
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. It was divided into five great-priories, the largest of which were Austria-Bohemia and Germany, in turn, divided into major priories or bailiwicks; one of the largest such became independent after the Protestant Reformation as the Order of Saint John (Bailiwick of Brandenburg).
The division of Latin Europe, on the other hand, was more fine-grained, into the
Hispanic (Iberian peninsula, at first known as the "Aragonese" langue, but in 1462 split into the Aragonese and the "Castilian" langue, the latter including Castille, Léon and Portugal),
Italian (Italian peninsula), Provençal, Auvergnat and Frenchlangues.
Finally, the Englishlangue included the order's possessions in the British Isles.
great priory Germany: The great priory of Germany was divided into eight bailiwicks (Balleien). From 1428, the seat of the great priory was at Heitersheim in Upper Germany.

A "Russian Grand Priory" with no less than 118 commandries, dwarfing the rest of the Order, was established by Paul I of Russia after the French occupation of Malta in 1798, initiating the Russian tradition of the Knights Hospitaller. Paul's election as Grand Master was, however, never ratified under Roman Catholic canon law, and he was the de facto rather than de jure Grand Master of the Order.
Following constitutional changes made in 1999, the Priory of England and The Islands was established (including the Commandery of Ards in Northern Ireland) alongside the existing Priories of Wales, Scotland, Canada, Australia (including the Commandery of Western Australia), New Zealand, South Africa, and the United States.[2] In 2013, the Priory of Kenya and in 2014 the Priory of Singapore were formed. Each is governed by a Prior and a Priory Chapter. Commanderies, governed by a Knight or Dame Commander and a Commandery Chapter,[3] may exist within or wholly or partly without the territory of a priory, known as Dependent or Independent Commanderies, respectively.[4] Any country without a priory or commandery of its own is assumed into the "home priory" of England and The Islands, many of these being smaller Commonwealth of Nations states in which the order has only a minor presence.[5]
