The team joined the Bundesliga in 1965, and saw the majority of its success in the 1970s, where, under the guidance of Hennes Weisweiler and then Udo Lattek, they captured five league championships with "Die Fohlen" (The Colts) team; a term coined as the squad were young with a fast, aggressive playing style. Mönchengladbach also won two UEFA Cup titles during this period and reached a European Cup final in 1977.
