Zmajska heraldika obuhvaća grbove i druge heraldičke oznake Družbe „Braća Hrvatskoga Zmaja” te zmajske grbove kao osobne znakove članova Družbe. Družba je tradicionalno hrvatsko svjetovno bratstvo i kulturna udruga koja čuva i obnavlja hrvatsku kulturnu baštinu i promiče identitet i postignuća hrvatske kulture, osnovana 1905. godine. Od osnivanja do danas Družba dodjeljuje svojim članovima osobne zmajske grbove u skladu s propisanim heraldičkim normama i pod stručnim nadzorom Zmajskoga heraldičkog ureda Družbe, čime se odlikuje kao jedno od tri područja žive heraldike u Hrvatskoj (uz municipalnu i crkvenu). Rad pozicionira zmajsku heraldiku u hrvatskoj heraldičkoj baštini, prikazuje njezin razvoj, djelovanje heraldičara i drugih koji su ju oblikovali, tipizira zmajske grbove prema vanjskim obilježjima oblikovanja u kronološki slijedne, jasno razgraničene tipove: četiri tipa do zabrane rada Družbe 1946. i četiri nakon njezine obnove 1990. godine. Kao prvo istraživanje ovoga materijala, ovaj rad otvara pitanja i postavlja teze na koje će se moći odgovoriti tek daljnjim istraživanjem.; Draconic heraldry is a term applied to coats of arms and other heraldic insignia of the ‘Brotherhood of the Croatian Dragon’ Society and the draconic coats of arms as personal symbols of the Society’s members. The Society, established in 1905, is a cultural association that strives to preserve and renew Croatian cultural heritage and promote the identity and achievements of Croatian culture. From its establishment until today, the Society has granted its members personal coats of arms in accordance with prescribed heraldic standards and under the professional supervision of the Draconic Heraldic Office, thus being one of three realms of living heraldry in Croatia (the other two being municipal and ecclesiastic heraldry). The paper positions draconic heraldry within the Croatian heraldic heritage, and presents its development and the activities of heraldists and other participants in its shaping. Prior to the ban of the Society in 1946 by the Communist regime, the heraldic office was implemented through the work of Emilij Laszowski, a co-founder of the Society and renowned heraldic expert, who hired a distinguished artist, Vjera Bojničić Zamola, to produce coats of arms under his guidance. Together they produced over 200 draconic coats of arms (and recreated some hundred historical Croatian noble coats of arms), today mostly preserved in the Native Collection in Ozalj. The ‘Genealogy’ of the Society, painted by Stjepan Kukec for its 35th anniversary, includes over a thousand of its members, among which more than 800 are presented with individual draconic coats of arms. After the renewal of the Society in 1990, the office was first led by Milovan Petković, who re-established the tradition and established cooperation with heraldic experts and artists. During his leadership and mostly with the help of Maja Bejdić as expert adviser and Mladen Stojić as graphical artist, some fifty draconic coats of arms were designed for Society members.
