Identity is a phenomenon defined in the social and humanistic sciences as an "act of identification", and every person shows what they are through a series of identities. With that analogy, the talk about identities can be continued with the talk about minorities. The minority can only exist in relation to the majority, and it is important that it obtains its rights and obligations in that relation. One of them is the right to use own language in appropriate communication situations. The Burgenland Croats are one of the most important Croatian national minorities. The beginning of emigration is mostly marked by the 16th century when Turkish threats became daily on the territory of today's Croatia. On the new soil, the Burgenland Croats faced problems of settlement, and later also with assimilation and integration. Hungarian and German influences were their everyday life. They strongly appreciated Catholicism, which for them was a thought phenomenon and a guide for preserving their identity. Also, they strongly advocated for a school system with the Croatian language of instruction. In the 19th century, the Burgenland Croats made progress in the formation of the literary language and advocated the touch of the Burgenland-Croatian and Croatian literary languages. Speech reality is diverse. There are five speech groups in the Burgenland area. Nevertheless, the Chakavian ikavian-ekavian speech prevails, which in some points coincides with, and in others differs from, the Chakavian speech of the Croatian language. The same does not apply to the lexical layer, which, compared to the Croatian language, contains a rather smaller number of words of foreign origin. During the 19th and especially in the 20th century, cultural and publishing activities achieved enviable results in organizing cultural and scientific events and publishing publications.
