Some alternative heraldic symbols were introduced by two distinct ethnic communities: the Transylvanian Saxons (German-speaking) and the Székely (Hungarian-speaking). The former group had its "one single seal" as early as 1224, though it is not recorded what that symbol was. According to Marțian, its design was the same as a 1302 seal, which depicts three kneeling men and a standing one holding up a crown. It was replaced in 1370 by a variant combining the Hungarian and Capetian arms of Louis I, alongside an eagle-and-rose composition. The original Székely symbol featured an arm holding a sword, often piercing through a crown, a bear's severed head, and a heart, sometimes alongside a star-and-crescent; the field, though often interpreted as "azure", was most likely "gules". Threatened by the peasant revolt of 1437, the estates of the realm established a regime of feudal privileges known as "Unio Trium Nationum". This event is traditionally held as the source of a new Székely coat of arms, which only shows the sun and waxing moon "(see Count of the Székelys)". Marțian notes that these two devices were also used in medieval armorials as visual representations of Cumania and of the Vlachs.
