Slavization of Eastern Europe!

The most striking peculiarity of the system is that a coat of arms does not belong to a single family. A number of unrelated families (sometimes hundreds of them), usually with a number of different family names, may use the same, undifferenced coat of arms, and each coat of arms has its own name. The total number of coats of arms in this system was relatively low – ca. 200 in the late Middle Ages. The same can be also seen in Western Europe, when families of different surnames but sharing clan origin would use similar coats-of-arms, the fleur-de-lis of the many Capetian families being perhaps the best known example.

One side-effect of this unique arrangement was that it became customary to refer to noblemen by both their family name and their coat of arms name (or clan name). For example: Jan Zamoyski herbu Jelita means Jan Zamoyski of the Jelita coat of arms (though it is often translated as ... of the clan Jelita ). From 15th to 17th centuries, the formula seems to have been to copy the ancient Roman naming convention: praenomen (or given name), nomen gentile (or Gens/Clan name) and cognomen (surname), following the Renaissence fashion. So we have: Jan Jelita Zamoyski, forming a double-barrelled name (nazwisko złożone, literally compound name). Later, the double-barrelled name began to be joined with a hyphen: Jan Jelita-Zamoyski. (See Polish names). The Polish émigrés of 19th century sometimes used adaptations of their names according to the Western European (mainly French) style, becoming (to use the same example): Jan de Jelita-Zamoyski or Jan Zamoyski de Jelita. Some would also keep the Latin forms of their surnames, as Latin was the official language of the Kingdom of Poland. Hence the popularity of Late-Medieval or Early-Modern forms such as "de Zamosc Zamoyski".

A single coat of arms could appear in slightly different versions, typically in different colours, depending on the custom of the family using it. Such modifications ( odmiany ) are still considered to represent the same coat of arms.

One of the most visually striking characteristics of Polish heraldry is the abundance of gules (red) fields. Among the oldest coats of arms in Poland, nearly half use a red background, with blue (azure) coming in a distant second. Nowhere else in Europe shows such a strong bias towards a particular color scheme. It follows however the well known heraldic custom of all Europe that the vassals would follow the colour-scheme of their overlord. It had even a practical meaning in the battlefield.

Other typical features used in Polish heraldry include horseshoes, arrows, Maltese crosses, scythes, stars and crescents. There are also many purely geometrical shapes for which a separate set of heraldic terms was invented. It has been suggested that originally all Polish coats of arms were based on such abstract geometrical shapes, but most were gradually "rationalized" into horseshoes, arrows and so on. If this hypothesis is correct, it suggests in turn that Polish heraldry, also unlike western European heraldry, may be at least partly derived from a kind of rune-like symbols: the TAMGAS used by nomadic peoples of the Steppe, such as the Sarmatians or the Avars, to mark property. However, the evidence about the origins of the system is scanty, and this hypothesis has been criticized as being part of the Polish noble tradition of romanticizing their supposed Sarmatian ancestry. On this matter, research and controversy continue.

A Polish coat of arms consists of: shield, crest, helm and crown. The 18th and 19th centuries fashion includes the mantling. Supporters, mottos and compartments normally do not appear, although certain individuals used them, especially in the final stages of the system's development, partly in response to French and German influence. Preserved medieval evidence shows Polish coats-of-arms with mantling and supporters.
