Béla III of Hungary
The coat of arms of Hungary depicts a double cross, which is often attributed to Byzantine influence as King Béla III of Hungary was raised in the Byzantine Empire in the 12th century, and it was during his rule when the double cross became a symbol of Hungary. Also the 'dual cross' is the consonant 'gy' in ancient Hungarian runic writing which reads "egy" (one) when it stands alone mostly, if not always, with "God" meaning.
