How to pronounce “Praesidium libertatis”
Classical Latin says ae as “eye” (prye-); Church Latin says it as “eh” (preh-). Stress falls on the second syllable of praesidium, because the syllable before the last is short, and on TAH in libertatis.
The story behind it
Word for word the motto says “protection of freedom”, in natural English “bulwark of freedom”. Praesidium is a Roman military word for a garrison or defensive post, so the image is of a guarded position that holds the line for liberty.
It is the motto of Leiden University in the Netherlands, founded in 1575. The phrase is modern Latin built from classical words, not a quotation from an ancient author, though libertas was a central political ideal in Rome.
The motto presents the university as a guardian of free thought and free inquiry, a role it states as its purpose rather than merely as a subject of study.
How to use “Praesidium libertatis”
A fitting motto for a university, a civil liberties organisation, a press freedom group or a society of defenders of rights. It also works as an inscription on a plaque or a commemorative piece for someone who protected others’ liberty, and as a keepsake for Leiden alumni.

Common mistakes
- Praesidium does not mean “president”. It means a guard, garrison or protection; the English word president comes from the related verb praesidere, “to preside”.
- The ending of libertatis is genitive, “of freedom”. Writing libertas or libertate would change the meaning or break the grammar.
- Do not respell it as presidium or praesidum: the standard form is praesidium, with the diphthong ae.
- Because this is a modern motto, it should not be credited to Cicero or another ancient author.
