 seu  (a verbo Graeco *diploma* ‘bis plicatum’) est ars gestorum inter legatos gregum civitatumve conloquiorum. Quae vox ad res diplomaticas inter civitates usitate spectat, administrationem necessitudinum inter gentes per deprecationem legatorum mercede conductorum de rebus pacis, belli, commercii, oeconomiae, et culturae. Foedera inter civitates a legatis plerumque componuntur antequam homines politicae periti ea confirmant.

In Graecia antiqua, diploma fuit charta, usitate bipartito plicata, quae confectionem cursus studii confirmavit. Tempore Imperii Romani, verbum *diplomatis* spectavit ad publicas peregrinationis chartas, sicut syngraphas et alias facultates eundi in viis imperialibus datas, duplices metallicas signa impressa ferentis laminas. Deinde significatio extensa est ad alia documenta includenda, sicut foedera cum tribubus externis. Saeculo duodevicensimo, populi Franciae gregem virorum publicorum ad legationes externas adsignatorum appellaverunt *corps diplomatique* 'corpus diplomaticum'. Sensu haud sollemni more, ars diplomatica est usus dexteritatis ad commodum rationis capiendum, vel invenire mutuo iucunda quaestionis communis responsa.

## Legati et missiones diplomaticae 
Hodie, verbum commune pro grege virorum diplomaticorum ex una civitate qui in alia civitate commorantur est missio diplomatica. Summum gradum diplomaticum est legatus, et quaevis missio diplomatica a legato ducta appellatur legatio, exceptis missionibus perennibus apud Consociationem Nationum, Societatem Civitatum Americanorum, et aliis societates "multilaterales," quibus etiam duces sunt legati. Corpus omnium diplomaticorum cuiuslibet civitatis virorum appellatur illius civitatis stipendia diplomatica (Anglice: *diplomatic service*); corpus autem omnium virorum diplomaticorum ad quamlibet civitatem adsignatorum appellatur corpus diplomaticum (Anglice: *diplomatic corps*). (Vide Gradum diplomaticum.)

### Europa 
Facultas artis diplomaticae factae est unum ex definientibus civitatis elementis, et ars diplomatica facta est postquam primae civitates conditae sunt, abhinc nonnulla millennia. Per historiam humanam, viri diplomatici missi sunt solum pro conloquiis peculiaribus; statim eorum missionibus finitis, domum redierunt. Tales viri usitate fuerunt cognati familiae regentis, vel homines summi gradus socialis ut, cum peterent conloqui cum hominibus aliae civitatis, auctoritatem haberent.

Exceptio notabilis fuit inter papam Romae et imperatorem Romanum Byzantii: procuratores papales, dicti apocrisiarii, perenne Constantinopoli commorati sunt. Nihilominus, post saeculum octavum, dissentiones inter papam et imperatorem, sicut Controversia Iconoclastica, haec vincula diremerunt.

### Conventus 
Quaestiones aliquando expeditae sunt per conventus inter gentes. Exempla talium conventuum sunt:

* Consilium Vindobonense (1815). Napoleone victo, fuerunt multi non compositae quaestiones diplomaticae. Hae fuerunt conformatio tabulae Europaeae, dispositio postulationum civilium et nationalistarum factarum a variis gregibus ethnicis et gentibus quae voluerunt habere autonomiam vel libertatem politicalem, et compositio postulationum variarum a variis Europae potestatibus factarum 

* Consilium Berolinense (13 Iunii–13 Iulii 1878) fuit conventus inter legatos Magnarum Potestatum legatosque Imperii Ottomanici Berolini anno 1878. Post Bellum Russicum Ottomanicum annorum 1877 et 1878, propositum conventus fuit iterum ordinare rerum status in Balcaniis.
