The
Visegrad Group, also called the
Visegrad Four, or
V4 is an alliance of four
Central European states
Czech Republic,
Hungary,
Poland and
Slovakiafor the purposes of furthering their
European integration as well as advancing their military, economic and energy cooperation with one another. The Group's name in the languages of the four countries is
Visegrádská ctyrka or
Visegrádská skupina (
Czech);
Visegrádi Együttmuködés or
Visegrádi négyek (
Hungarian);
Grupa Wyszehradzka (
Polish); and
Vyšehradská skupina or
Vyšehradská štvorka (
Slovak). It used to be sometimes referred to as the
Visegrád Triangle, since it was an alliance of three states at the beginning – the term is not valid now, but appears sometimes even after all the years since the dissolution of
Czechoslovakia in 1993.
