Architectural modernism emerged in the wake of the early 20th-century European avant-gardes. The movement was fueled by industrial capitalism and the thrilling technological progress unfolding before everyone's eyes. The break with the past had been deliberately ushered in by intellectual, artistic, and technical movements since the mid-19th century. The Crystal Palace, for instance, designed by Sir Joseph Paxton, was built in London to host the Great Exhibition of 1851 and represented a structural revolution in the use of lightweight materials such as iron and glass.
