Freedom House ranks the Somaliland government as partly democratic. Seth Kaplan (2011) argues that in contrast to southern Somalia and adjacent territories, Somaliland, the secessionist northwestern portion of Somalia, has built a more democratic mode of governance from the bottom up, with virtually no foreign assistance. Specifically, Kaplan suggests that Somaliland has the most democratic political system in the Horn of Africa because it has been largely insulated from the extremist elements in the rest of Somalia and has viable electoral and legislative systems as well as a robust private sector-dominated economy, unlike neighbouring authoritarian governments. He largely attributes this to Somaliland's integration of customary laws and tradition with modern state structures, which he indicates most post-colonial states in Africa and the Middle East have not had the opportunity to do. Kaplan asserts that this has facilitated cohesiveness and conferred greater governmental legitimacy in Somaliland, as has the territory's comparatively homogeneous population, relatively equitable income distribution, a common fear of the south, and absence of interference by outside forces, which has obliged local politicians to observe a degree of accountability.
