The rhizome is a theoretical concept developed by Deleuze and Guattari which rejects the notion of a linear trajectory of thought in favour of a multiplicitous network of ideas, relations and entry points that ceaselessly establishes connections. The theory states that a rhizome is a map and not a tracing.
Edouard Glissant adopted the concept in relation to the creation of African diasporic identity, as it 'maintains the idea of rootedness but challenges that of a totalitarian root.'
