Which Spanish artist is considered a founder of Cubism?

The Spanish artist considered a founder of Cubism was Pablo Picasso.

Pablo Picasso was born in Málaga, Spain, in 1881 and became one of the central figures of twentieth-century art. His 1907 painting Les Demoiselles d’Avignon is often treated as a proto-Cubist breakthrough because it fractured conventional perspective and presented figures through sharply simplified, angular forms.

Picasso developed Cubism in close partnership with Georges Braque, a French artist. Between roughly 1908 and 1914, the two artists investigated multiple viewpoints, geometric fragmentation, and the tension between flat surfaces and three-dimensional subjects. Their collaboration produced the foundations of Analytic Cubism and later helped lead to Synthetic Cubism and collage.

Calling Picasso “the” founder is a useful quiz answer but simplifies the history. Braque was an essential co-innovator, and artists such as Jean Metzinger, Albert Gleizes, Juan Gris, and Fernand Léger expanded Cubism’s reach. Francisco Goya, Joan Miró, and Salvador Dalí were also major Spanish artists, but they belonged to earlier or later artistic contexts rather than founding Cubism.
