Also known as an amateur heraldist and graphic artist, the young Caragiale published his works sporadically, seeking instead to impose himself in politics and pursuing a career in the civil service. He was associated with the Conservative-Democratic Party, and then the People's League, and ultimately raised controversy by supporting the Central Powers during their occupation of Romania. He afterwards focused on literature, and, during the late 1920s and early 1930s, published most of his prose texts in the magazine Gândirea. The illegitimate and rebellious child of influential playwright Ion Luca Caragiale, he was the half-brother of Luca Caragiale, a modernist poet who died in 1921, and the posthumous son-in-law of author Gheorghe Sion. Mateiu Caragiale was loosely affiliated with Romanian Symbolism, a figure noted for his dandyism, eccentricity and Bohemianism, and, for much of his life, a regular presence in the intellectual circle formed around Casa Capşa restaurant. His associates included the controversial political figure Alexandru Bogdan-Piteşti, cultural animator Mărgărita Miller Verghy, and poet Ion Barbu, who was also one of his most dedicated promoters.
