Party was founded in 2015 when Miodrag Lekić, leader of the opposition Democratic Front, split from the alliance due to disagreements with its constituent parties, and formed the new moderate right political subject.[3]
In September 2016, DEMOS decided to enter the Key Coalition with URA and SNP in order to participate at the forthcoming parliamentary election, winning four parliamentary seats.[4] In the summer of 2017 a rift occurred within the party, which resulted in a split, with a conservative faction led by Goran Danilović and Goran Radonjić deciding to form a new party, called United Montenegro.[5] The split left Demos with two MPs, as the remaining two defected to the new party.
