Oberstvení

Could you clarify what "oberstvení" refers to? I want to ensure I write an accurate, neutral wiki-style article. For example, is it:

- a historical or cultural term in Czech or another language,

- a geographic place (town, region) named Oberstvení,

- a surname,

- or a term used in linguistics, law, military, or another field?

If you provide the intended meaning or context, I’ll draft a concise, neutral entry under 300 words with sections such as definition, etymology, usage or history, and related topics.
