On 10 December 1991, in a referendum boycotted by local Azerbaijanis, Armenians in Nagorno-Karabakh approved the creation of an independent state. A Soviet proposal for enhanced autonomy for Nagorno-Karabakh within Azerbaijan satisfied neither side and a full-scale war subsequently erupted between Azerbaijan and Nagorno-Karabakh, with the latter receiving support from Armenia. According to Armenia's former president, Levon Ter-Petrossian, the Karabakh leadership approach was maximalist and "they thought they could get more."
