The flag of Dalmatia consists of two identical horizontal stripes of blue and yellow. Like the Croatian flag, it draws its modern roots from the period of the Austrian Empire, specifically from the Kingdom of Dalmatia. The coat of arms of Dalmatia - blue with three golden crowned leopard (lion guardant) heads - is never used on it, it is a simple yellow over blue bicolour without any emblem, as was custom of Austrian "landesfarben". The coat of arms was possibly sometimes set in it, but this was far from official. After 1918 there was no administrative region of Dalmatia, and no flag was used. The Dalmatian counties of modern-day Croatia inherit blue and yellow colours, but no one has the right to "claim" the entire historical Dalmatian coat of arms. The coat of arms is, on the other hand, included in the Croatian coat of arms and the flag.
However, mostly as souvenirs, the banners of arms of Dalmatia were sometimes used, and occasionally Italian groups with pretensions on Dalmatia, or those who left Dalmatia after World War II, used such flags in the last 50 years - always unofficially. An alternate version of the flag, featuring bleu celeste instead of azure, is almost indistinguishable from the modern flag of Ukraine, though there is no connection between the two.
