Sécus

Sécus is a term that can refer to several distinct concepts, primarily in the context of language and history. One notable usage of "Sécus" is as a former name for the Dacian people, an ancient Indo-European group who inhabited the regions north of the Lower Danube in the 1st century BC and 1st century AD. They were known for their conflicts and interactions with the Roman Empire, particularly during the Dacian Wars of Emperor Trajan. The Dacians are believed to have spoken a Thraco-Dacian language, a branch of the Indo-European language family.

Another significant meaning of Sécus relates to the Székely people, a Hungarian ethnic group who live primarily in Székely Land, a region in the eastern part of modern-day Romania. Historically, the Székelys held a distinct status within the Kingdom of Hungary, often serving as border guards. The term Sécus is sometimes used as an older or regional designation for the Székelys or their language, which is a dialect of Hungarian. The exact etymology and relationship between these different uses of "Sécus" are subjects of historical and linguistic study, with potential links to ancient ethnonyms and cultural exchanges in Eastern Europe.
