Kou Voravong
The political crisis caused by his assassination, barely two months after the Geneva Agreements which prepared to restore peace in Indochina, contributed to bring down the current neutralist government (pro-French) which was replaced by a progressive one (pro-American) in extremely tense atmosphere of the Cold War between Russia and the United States. From 1955 indeed, the political history of this small landlocked country fell trapped inexorably in the ideological confrontation between the capitalist United States and the communist Soviet Union, annihilating any hope of national unification.
Kou Voravong
King Sisavang Vong declared officially the French protectorate's continuity. But on September 11, his cousin and Viceroy, Chao Phetsarath accompanied by his two brothers, Chao Souvanna Phouma (ເຈົ້າສຸວັນນະພູມາ) and Chao Souphanouvong (ເຈົ້າສຸພັນນຸວົງ), supported by Chinese and Viêt Minh nationalists, 
proclaimed the Lao Issara Government and required the immediate independence of Laos, refusing all discussions with France. Therefore, struggles between different factions started out.
