It gained wider attraction following the German Revolution of 1918, serving as the headquarters for revolutionaries during the Bavarian Soviet Republic.
In 1818, the brewer Georg Hartl, owner of the Zum Kleinen Löwengarten beer hall on what was then Landsberger Straße (today Bayerstraße), bought the Fuchsbräu, which was founded in the 15th century.
From 1829 to 1832, Max J. Boshart ran the Härtlisches Brauhaus, from 1832 to 1844 it was owned by the "Braugrafen" Theobald Graf von Buttler-Haimhausen and was called Buttler-Bräu.
After his death in 1874, his widow Anna Mathäser continued the business, with the brewery using the name Mathäser-Bräu from 1874 to 1884 as well as the former name of Zum bayerischen Löwen (English: The Bavarian Lion) resumed.
The former factory rooms were converted into beer halls and August Exter built a new wing on the street side with a representative facade in the neo-Renaissance style.
[2] At the end of the First World War, a workers' and soldiers' council was constituted in the Mathäser-Bräu under the chairmanship of Kurt Eisner on the night of November 7–8, 1918.
The Munich artist Oskar Maria Graf called for a revolution in 1919, for which he rented the Mathäser; however, the event had extremely low turnout.
Ernst Eckstein, the chief architect of the Löwenbrauerei, designed a five-story, doulbe-gabled building along Bayerstraße with reinforced concrete construction.
In 1958, the Reiss family, operators and tenants, represented the Mathäser with the restaurant Oberbayern at the World Exhibition in Brussels.
As a token of gratitude, the city of Bordighera sent five thousand carnations the following year to decorate the "Spring Festival" in the ballroom of the Bierstadt.
In 1967, driven by Löwenbräu AG, they engaged in the German Pavilion's "Restaurant Bavarois" at the 1967 International and Universal Exposition.
After the renovation, the Mathäser reopened with Sam Peckinpah's Convoy marking the heyday of Hollywood action cinema.
