The party was created amid the 2015–2016 protests in Moldova and growing dissatisfaction with the ruling parties among citizens. On 23 December 2015, Maia Sandu posted a YouTube video in which she announced her intention to form a new political party. Her stated reason for doing so was the creation of a grassroots party, that would function based on the principles of internal democracy and would be financed through small donations. Sandu was elected as leader of the PAS on 15 May 2016 and the party was officially registered by the Ministry of Justice on 26 May. At the time of registration, the party had 7,500 members and 20 local organizations. In February 2017, the party applied for membership of the European People's Party.
