However, there are several overlapping definitions, including ones related to culture, language, politics, and history, and sometimes involving neighbouring countries. The demonym associated with Flanders is Fleming, while the corresponding adjective is Flemish. The official capital of Flanders is the City of Brussels, although the Brussels-Capital Region that includes it has an independent regional government. The powers of the government of Flanders consist, among others, of economic affairs in the Flemish Region and the community aspects of Flanders life in Brussels, such as Flemish culture and education.
