Invexillology,defacement is the addition of a symbol orcharge to a flag.[1][2][3] For example, theAustralian flag is the BritishBlue Ensign defaced with aSouthern Cross in thefly.
In the context ofvexillology, the word "deface" carries no negative connotations, in contrast to general usage. It simply indicates a differentiation of the flag from that of another owner by addition of elements. For example, manystate flags are formed by defacing the national flag with a coat of arms.
Where countries pass through changes of regime with contrasting ideological orientations (monarchist/republican, fascist/democratic, communist/capitalist, secular/religious etc.) – all of which, despite their differences, claim allegiance to a common national heritage expressed in a venerated national flag – it can happen that a new regime defaces that flag with its own specific emblem while keeping the basic flag design unchanged. Such changing ideological emblems appeared over time, among others, on the flags ofItaly,Hungary,Romania,Germany (West and East; see illustration),Ethiopia, andIran.[citation needed] For example, during theHungarian Revolution of 1956 and theRomanian Revolution of 1989, insurgents tore the emblem of the regime that they opposed out of the national flag and waved the flag with which they identified.[4][5]
An already defaced flag can be further defaced. For example, theAustralian flag is a defaced BritishBlue Ensign. TheAustralian Border Force Flag is further defaced with the words "Australian border force" in block letters.[citation needed]
