Chagall nurtured a lifelong interest in the theatre, but his passion for the stage was given its first full expression as part of his duties as Arts Commissar in Vitebsk. All theatre was political in these times of revolution and unrest, with theatre companies themselves often products of political manoeuvring. The towns post-Revolution theatre scene was bolstered by new regime-supported enterprises such as the Vitebsk Theatre of Revolutionary Satire (TEREVSAT), which became synonymous with agitprop plays. TEREVSAT was the first theatre for which Chagall designed both costumes and sets on a regular basis. Chagall also undertook many theatre design commissions in Moscow and Petrogradwhile still working at the art college in Vitebsk, travelling back and forth between the cities.
