The Catalan conflict attracted special European and broader international attention with the unilateral referendum and declaration of independence of 2017. After offering some historical, comparative, constitutional, and political insights to help to understand this conflict, the present chapter makes ten proposals to accommodate territorial pluralism in Spain. These multiple ways of accommodation are not a pure product of abstract thinking but are rather inspired by existing institutions and practices in comparable cases. By showing that comparative law and politics offer potential ways to address the Catalan challenge, we may conclude that their implementation is obstructed by a lack of political will within the context of a constitutional order conceived and interpreted at its core monistically.
