[Native Moravians speak Moravian dialects that are influenced by neighboring Slovak speakers. Due to these cultural and linguistic links to Slovakia many ethnographers until 20th century used to consider Moravian Slovaks as a people which politically belonged to Moravia and Lands of the Bohemian Crown but ethnografically and culturally to the Slovak ethnic group. People of Slovácko call themselves Slováci, which means Slovaks.
