What belief were modernists driven and what intensified it?

Modernists were driven by the belief in progress and the idea that human innovation and reason could lead to improvement in society, culture, and the individual experience. This belief was intensified by rapid advancements in technology, science, and the arts during the late 19th and early 20th centuries, as well as the upheavals of World War I, which challenged traditional norms and values, prompting a reevaluation of the role of humanity in shaping its own destiny.
