This paper explores the work of the so-called group The Prague Four consisting of Milivoj Uzelac, Vilko Gecan, Marijan Trepše and Vladimir Varlaj, their stylistic expression and significance for Croatian art at the beginning of the 20th century. They were an unofficial group of artists connected above all by friendship and a short, but significant stay in Prague in the period after the First World War. The stylistically eclectic art scene of Prague and avant-garde tendencies will be presented, with an emphasis on expressionism, with which they opened a new development path for Croatian painting upon their return to Zagreb. Furthermore, it is inevitable to look back on the significant artistic legacy of the older generation, especially Miroslav Kraljević and his interpretation of Cézanne's style of painting, and explore his role in the formation of the stylistic expression of the Prague Four. The Spring salon was an exhibition manifestation, with total of twenty-four exhibitions, which brought together a wide circle of artists, mostly of the younger generation and enabled the presentation of contemporary art trends. Prominent VII. exhibition in 1919. was significant for introducing the Prague Four to the domestic art scene.
