Why did Ezra Pound turn from Imagism to Vorticism in 1914?

In 1914, Ezra Pound transitioned from Imagism to Vorticism as his focus shifted toward a movement that explicitly rejected 19th-century sentimentality and sought to align art with the realities of industrialization.123

While Imagism emphasized sparse, direct language and visual clarity, Vorticism—founded by Wyndham Lewis—extolled the energy of machines and machine-made products. Vorticists utilized a "bare-bones" vocabulary intended to resonate with the mechanical forms found in factories and shipyards. By embracing abstraction and the dynamic nature of the machine age, Pound and his contemporaries aimed to sever ties with the "suffocating" Victorian past and advance into a new era. Following Pound's shift, Amy Lowell largely assumed leadership of the Imagist group.1342
