Decentralization, "the transfer of rule from the central government level to regional and local levels" (Demmelhuber, Sturm, and Vollmann 2020), has been on the rise globally since the early 1990s (see Figure 1). Decentralization is one among several forms of power-sharing between the center and the regions in a nation-state 1 . It is a broad category which subsumes topdown and bottom-up processes of social, constitutional and cultural change. Its implementation carries a normative quality (see Wibbels 2006, 166): The concept implies improved democratic standards when implemented (see Jones 2009) and it is regularly included in a broad set of indices on the quality of democracy. 2 These effects of decentralization are difficult to prove as, among others, Treisman 3 has demonstrated. He argues, "it is hard to reach any general conclusions about whether political -or administrative, or fiscal -decentralization will improve or impair the quality of government and economic performance." (Treisman 2007, 274) 4 Therefore, any one-size-fits-all prescriptions of decentralization are not particularly helpful (see Hutchcroft 2001, 24). It would moreover be incorrect to assume that the predominance of autocratic regimes in the MENA countries precludes decentralization by definition. On the one hand, there is no rule of thumb for normative judgments. It is moreover of high importance to move beyond the association of authoritarianism with centralization and democracy with decentralization. […] The process of decentralization may sometimes promote democracy, but it is quite easy to conceive of an "autocratic decentralization" in situations where authority is devolved to authoritarian enclaves at the local level (Hutchcroft 2001, 33).
