Berlin Congress of 1878 totally neglected interests of the Albanians. Subsequently, Treaty of Berlin became the starting point for creation of the Albanian League of Prizren （1878-1881） as well as future development of the Albanian national movement. Russia as well as other Great Powers played a controversial role in that context.展开更多

The legacies of these two political and historical landscapes have had a hand in shaping and disfiguring the nascent governments that would be born in Africa with vanguard parties not tolerating opposition. In a bid to stay in leading positions, as founding fathers of revolution, incumbent governments have used different tools, some very unorthodox, from brute force, genocides, governments of national unity and violent elections to stay in power and destroy opposition. This paper seeks to trace how Zimbabwe has fared in establishing a democratic government from Lancaster to the 2013 March referendum. Zimbabwe, following a Lancaster House Agreement C1979）, like Kenya （1960）, held elections in 1980, making R. G. Mugabe the first black Prime Minister and C. Banana the President. Some scholars have argued that the 1980 elections have been the only free and fair elections in Zimbabwe＇s history of elections. To measure the level of democracy in Zimbabwe, the paper shall highlight the euphoria at 1980, read through gukurahundi of 1983, the unity accord of 1987, select parliamentary and presidential elections, the fast track land reform of 2002, the 2009 Government of National Unity as well as the 2013 constitution amendment. The study shall largely make use of desktop and interviews of ordinary Zimbabweans, politicians, and students in universities with regards to matters of governance. The paper concludes that post communist governments have struggled to establish democracy.展开更多
