The House of Bethlen is the name of two Hungarian ancient noble families, Bethlen de Iktár and Bethlen de Bethlen. Although both families have similar coat of arms, they have no proven mutual ancestry. Both can trace their noble lineage up to the 12th and 13th centuries, and their family members played a significant role in the history of Transylvania and Hungary within the Habsburg Empire.
