Answer
Vienna Secession, a movement that Loos's views helped establish, emerged as a reaction against the prevailing historicism and ornamentation in architecture. Loos advocated for simplicity, functionality, and the rejection of unnecessary decoration. His ideas resonated with other architects and artists, leading to the formation of the Vienna Secession in 1897. This movement sought to break away from traditional artistic norms and embrace a more modern, progressive approach to design.
