👉 Oblasts are regions that are defined by their boundaries, usually including a central administrative area or region. They can be located in various countries and have different characteristics depending on their location. In Russia, for example, there are five oblasts (regions): Karelia, Sakha Republic, Dagestan, Bashkortostan, and Khabarovsk. These regions are geographically separated from one another but share cultural, historical, and economic ties through their shared history.
