Els Quatre Gats is a café in Barcelona, Catalonia, Spain, that famously became a popular meeting place for famous artists throughout the modernist period in Catalonia, known as Modernisme. The café opened on 12 June 1897 in the famous Casa Martí, and served as a hostel, bar and cabaret until it eventually became a central meeting point for Barcelona's most prominent modernist figures, such as Pablo Picasso and Ramon Casas i Carbó. The bar closed due to financial difficulties in June 1903, but was reopened and eventually restored to its original condition in 1989.

Ramon Casas i Carbó was a Catalan artist. Living through a turbulent time in the history of his native Barcelona, he was known as a portraitist, sketching and painting the intellectual, economic, and political elite of Barcelona, Paris, Madrid, and beyond. He was also known for his paintings of crowd scenes ranging from the audience at a bullfight to the assembly for an execution to rioters in the Barcelona streets. Also a graphic designer, his posters and postcards helped to define the Catalan art movement known as modernisme.
