Bosniaks are a South Slavic ethnic group and nation native to Bosnia and Herzegovina and constitute the largest ethnic group in Bosnia and Herzegovina, followed by Serbs and Croats. They share a common ancestry, culture, history and language emanating from the Bosnian historical region; and traditionally and predominantly adhere to Sunni Islam for which reason they are often also referred to as Bosnian Muslims although this is an imprecise ethnic descriptor today. The Bosniaks constitute significant native communities in Serbia, Montenegro, Croatia and Kosovo as well. Largely due to displacement stemming from the Bosnian War and Genocide in the 1990s, they also form a significant diaspora with several Bosniak communities across Europe, the Americas and Oceania.
