Sound trumpets! Let our bloody colours wave! And either victory, or else a grave.

Field signs were used in early warfare at least since the Bronze Age. The word standard itself is from an Old Frankish term for a field sign (not necessarily a flag). The use of flags as field signs apparently emerges in Asia, during the Iron Age, possibly in either China or India. Early field signs that include, but are not limited to a flag, are also called vexilloid or "flag-like", for example the Roman Eagle standard or the dragon standard of the Sarmatians. The Roman Vexillum itself is also "flag-like" in the sense that it was suspended from a horizontal crossbar as opposed to a simple flagpole.

Use of simple flags as military ensigns becomes common during the medieval period, developing in parallel with heraldry as a complement to the heraldic device shown on shields. The maritime flag also develops in the medieval period. The medieval Japanese Sashimono carried by foot-soldiers are a parallel development.

Some medieval free cities or communes did not have coats of arms, and used war flags that were not derived from a coat of arms. Thus, the city of Lucerne used a blue-white flag as a field sign from the mid 13th century, without deriving it from a heraldic shield design.
