Flags of Domlandia
It is difficult to get an understanding of what Domlandian flags were prior to the late 19th century, due to both poor record keeping on the part of historians and deliberate destruction of old artifacts by the Biggonian SIS during both period of occupation in order to destroy a national identity. However, it is understood that over history numerous flags were used to represent the various Domlandian polities. The few times Domlandia was unified, it would only be for a single generation under a warlord-esque figure and therefore their flags were not reused by successors. One of the few sources surrounding flags used by pre-modern Domlandians was that of accounts of the Biggonian Kingdom war, where a unified Domlandia fought against a coalition of Biggonian Kingdoms. Artists illustrations and eyewitness accounts state that the Domlandian army would tend to carry local banners, carrying words, family symbols, or various gods and spirits which represented the individual village or noble family the troops belonged to. Therefore it can be concluded that little in the way of a Domlandian Flag existed prior the mid 19th century.
Sultanate of Domlandia (1857/8-1874)
The last time an independent Domlandian monarchy ruled the nation was also during the rise of Biggonian nationalism in the mid to late 19th century. Under the ----- dynasty, the Sultanate attempted to formalise and creating a long-lasting system, which they did through creating a flag. Although few photos exist and there are no surviving instances of the Domlandian flag during this period; vexiologists have tried their best to reconstruct the Domlandian Sultanate's flag based on as much information as possible. The Domlandian Sultanate was destroyed during the invasion of Domlandia by the Biggonian Confederation, and was reformed as the Viceroyalty of Domlandia the following year.
The Viceroy would be elected by the Biggonian Imperial Diet to serve for a five-year term.
