Guillermo Gómez-Peña and Francis Alÿs are two artists who utilize performances in order to interpret the relationship between social, political and cultural forms in today's society. This thesis characterizes their precedents in various artistic movements from the 20th century as well as focuses on the originality of these artists' approaches to performance. One particular avant-garde movement that had a profound effect on their artistic and literary pursuits is the Situationist International (SI), an artistic and political movement active in Europe from 1957 to 1972, made up of artists and theorists who advocated the creation of theoretical and active situations in order to reflect upon the social climates of urban environments. My research will explore how the values of the SI play out in both Gómez-Peña and Francis Alÿs's work created during the last decade of the 20th century, which I suggest are highly influential upon their performance projects. I will consider the ways in which these artists interpret certain artistic methodologies and ultimately reconfigure them in a way that generates a radical approach to performance.
