After Berlin Conference in 1884 to 1885, Somalia was partitioned into five parts by Britain, Italy, and French. In 1960 two parts gained independence and formed the Somali Republic, and since then successive Somali governments sought to incorporate the other three parts of Somali territories under Ethiopia, Kenya and French Somaliland known as Djibouti into Greater Somalia.The aim of this study has been to explore and analyze the causes, and the impact of the Somalia’ irredentism on political stability in Somalia. In more specifically, the main objective has been to critically examine how Somali irridentism policy has been pursued, what challenges faced and how it has affected the political stability of the post-colonial Somali state from 1960 to 1990.The analysis presented in this study has shown that the causes of Somali irredentism are combined factors that helped rise Somali irredentism. The analysis has argued that Somalia’s quest for irredentism policy had a huge impact on Somalia’s political stability, including, but not limited to, creating enemies and alienating allies from neighbouring countries to western and eastern blocs, as well as interstate conflict with Ethiopia which ended with Somalia defeat. Finally, Somalia’s defeat, which resulted from irredentism’s venture, caused disunity among the national army, refugee crisis, financial burden and the rise of armed opposition movements that finally ousted the military regime led by Siad Barre. This was followed by state collapse and protracted civil war.

Territorial disputes between Japan and South Korea (Dokdo/Takeshima) and Japan, Taiwan, and China (the Senkaku/Diaoyu Islands) are characteristic of post-war East Asian diplomacy. This thesis explores these ongoing territorial disputes, problematizing Realist arguments by which these disputes are analyzed as matters of territorial or resource nationalism, or as the result of legal complications or security concerns. Instead, it is argued that we should look to ideologies of nationalism to understand seemingly extreme emotional reactions over these 'rocks' which threaten to destabilize Northeast Asia. These islands are treated as 'sublime' symbols of the nation and irredentist arguments which support the Japanese, Korean, and Chinese positions read history through a lens of essentialized notions of 'a people' or 'a nation', and in the process help define both.

El Plan de San Diego is the name of an important document in Texas history, but the document and surrounding history is usually discussed with little or no reference to the town of San Diego, Texas, the people who lived there, or the cultural landscape. The Plan de San Diego is an unsuccessful rebellion that is one of the few documented irredentist revolts in U.S. History, it is also a written document calling for return of lands in a multi-ethnic call to arms advocating the recovery of territory by people of Mexican descent in 1915, named for the town San Diego, TX. After the discovery of this Plan, Mexican-Americans were persecuted, violently suppressed, and murdered: 300-5,000 people of Mexican descent died violently following the discovery and publication of the Plan de San Diego in what historians have called the “Bandit Wars”. San Diego, Texas residents and the entire U.S.-Mexican borderlands changed after the discovery of the Plan. My research investigates the political landscape and changes in material and cultural assemblages during and after the Plan, examining how descendant communities retained ties to place and remembered this event in the community of San Diego. Archival research, Historical archaeology and media representations of San Diego explore expose the everyday lives, settlement patterns, and subsistence strategies of the residents of San Diego before and after 1915, showing the material and social effects of the failed rebellion. The socio-political landscape that helped create Mexican-American culture in San Diego is a silenced, violent, and misunderstood chapter of Texas history that shapes the current borderlands and contributes important insights into the study of sites of rebellion and retaliation worldwide. / text
