Anti-Ukrainian sentiment, Ukrainophobia or anti-Ukrainianism is animosity towards Ukrainians, Ukrainian culture, the Ukrainian language, Ukraine as a nation, or all of the above. Modern scholars divide anti-Ukrainian sentiment into two types. One type consists of discrimination against Ukrainians based on their ethnic or cultural origin, typical forms of xenophobia and racism. Another type consists of the conceptual rejection of Ukrainians as an actual ethnic group and the rejection of the Ukrainian culture and language, based on the belief that they are "unnatural" because they were "artificially formed"; at the turn of the 20th century, several Russian nationalist authors asserted that the Ukrainian identity and language had both been artificially created in order to "undermine" Russia.
