The alliance was established on 13 February 2016. The name of the party reflects the three politicians who signed the memorandum founding the alliance. The surnames of Seyran Ohanyan (former
Defence minister of Armenia), Raffi Hovannisian (Heritage Party Leader), and Vartan Oskanian (Unity Party Leader), were used as an acronym to name the alliance. Prior to the election, the alliance stated that they would be open to working with all other
political parties within Armenia for the betterment of the country. However, the alliance is very critical of the
Republican Party of Armenia and stated that they would refuse to work with them. Meanwhile, the
Sasna Tsrer Pan-Armenian Party, the
Social Justice Party, and the
People's Party announced their support to the ORO Alliance. The
Third Republic Party announced its intention to join the ORO Alliance, however, the party ultimately decided not to cooperate with the alliance. ==Electoral record==
