The Durmstrang Institute has a larger student population than Hogwarts (Pm). Durmstrang has a reputation for teaching duelling and other martial magic to its students. During some periods of its history, it has also gained the reputation for teaching them the Dark Arts, and during the headmastership of Igor Karkaroff (c. early 1990s) the school did not admit Muggle-born students (GF11).
Viktor Krum was often unhappy as a student there because many of his classmates revered Gellert Grindelwald. (DH8).
The Durmstrang uniform includes blood red robes and furs.
