Another referendum was held on 20 February 2017, with an 87.6% vote in favour on a 76% turnout for instituting a new constitution. This constitution among other changes turned the government from a semi-presidential to a fully presidential model. Its name was changed from "Constitution of the Nagorno Karabakh Republic" to "Constitution of the Republic of Artsakh", though both remained official names of the country. The new name implies a claim to the areas occupied beyond the former Nagorno-Karabakh Autonomous Oblast, and the Presidential system allows for quicker decisions on security matters. The referendum is seen as a response to the 2016 Nagorno-Karabakh clashes.
