It is a blue flag with a golden strip and a "sun-star" and crescent moon, both perceived as ancient Székely symbols.

On the side of the flagpole within the upper blue bar is an eight-pointed golden star and a silver crescent moon.

[1] According to Kónya's original description of the flag, the eight-pointed "sun-star" symbolizes the eight historical Székely seats (Bardóc-Miklósvárszék, Csíkszék, Gyergyószék, Kézdiszék, Marosszék, Orbaiszék, Sepsiszék and Udvarhelyszék).

In fact, in 1580, they appeared as components of the coat of arms of the Principality of Transylvania and the Transylvanian Diet adopted them as official Székely symbols in 1659.

Subsequently, the crescent moon and the sun started to appear on flags and coats of arms of the Székely seats.

In reality, this version has no historical precedent, as it was created in the second half of the 20th century in the area of Csíkszék using the basic colors of the typical Székely female folk costume as a "revolt" against the Romanian authorities.

[5][6] The black-and-red version is used by the Székely's World Alliance, registered in the United States;[7] and it is also preferred by motorcyclists and rockers.

[2] Possibly,[2] today's official flag can be traced back to the times of the Transylvanian prince Moses Székely.

[11] The Romanian authorities responded to this with numerous final judgments issued since 2013, according to which the Székely symbols must be removed from all public buildings and spaces, including in their interior.
