**Kashubian Unity Day** (csb: *Dzéń Jednotë Kaszëbów*, Polish: *Dzień Jedności Kaszubów*) is an annual festival celebrated every March 19 to commemorate the first historical written mention of [Kashubians](/source/Kashubians), in [Pope Gregory IX](/source/Pope_Gregory_IX)'s Bull of 19 March 1238. In this bull, the Pope referred to Prince [Bogislaw I](/source/Bogislaw_I) of Pomerania (d. 1187) as *duce Cassubie* (duke of [Kashubia](/source/Kashubia)).

Sponsored and coordinated by the [Kashubian-Pomeranian Association](/source/Kashubian-Pomeranian_Association), the annual Kashubian Unity Day is designed to promote Kashubian culture. It includes folk art fairs, exhibitions, crafts, and a tournament of the traditional Kashubian card game, "Baśka." Another, newer, feature is the competition to better the world record for the number of people simultaneously playing the [accordion](/source/Accordion).[1] Kashubian Unity Day is also noted for its use of social media to promote the event,[2] and its [Facebook](/source/Facebook) page is a very useful source for both festival information and news pertaining to Kashubian life and culture.[3]
