Alternattiva Demokratika was founded in 1989 when former Malta Labour Party President Toni Abela and former LabourMP and Parliamentary whipWenzu Mintoff joined a number of environmental activists to form the new political party. Abela and Mintoff had resigned their posts in protest at the presence of certain elements in the Labour Party tainted with political violence and corruption. For this Abela and Mintoff were expelled from the Labour Party. Mintoff retained his seat in Parliament and, between 1989 and 1992 was effectively an MP for the new party as well as its first Chairperson. Alternattiva Demokratika first stood for the 1992 national elections when it obtained 1.69% of first preference votes and no seats. In the subsequent elections of 1996 and 1998 the Party's share of the vote declined. Following the 1998 result, Abela and Mintoff resigned and returned to the Labour Party. Harry Vassallo replaced Mintoff as Chairperson of the Party in 1999. In 2003 the party campaigned for a Yes vote in the referendum on membership in the European Union. In the election that year the Party obtained only 0.7% of first preference votes having campaigned for second preference votes in order to secure the earlier refendum result and Malta's entry into the European Union. In 2004 the party obtained a remarkable result in the European Parliament election with 9.33% of first preference votes cast and the party's candidate, Arnold Cassola narrowly failing to be elected as MEP. In the Maltese general election of 2008, the party increased its share of the vote to 1.31%. After ten years at the helm, Vassallo resigned as Chairperson and was replaced by Cassola. Barely a year later Cassola handed his resignation following the Party's poor showing at the European Parliament Election in June 2009. Cassola was replaced by Michael Briguglio in October 2009 but returned to the helm following Briguglio's resignation in 2013. Carmel Cacopardo was elected to lead in 2017. Alternattiva Demokratika holds one seat in the Local Council of Attard. In the general election of 2013, Alternattiva Demokratika obtained its best ever result with 5,506 votes in total across all districts where they ran candidates but failed to win a seat in parliament. The party's best result was in District 10 where then party leader Michael Briguglio received 741 first preference votes and a further 154 transfers before being eliminated after the 17th count. The quota for that district was 3,679 votes. After the election some Democratic Alternative supporters claimed this raised a number of issues regarding representation. Talks are expected to take place during a constitutional convention with regards to addressing anomalies with the current Maltese electoral system. Alternattiva Demokratika entered into preliminary coalition negotiations with the Nationalist Party in April 2017 to determine if they could cooperate to unseat the Labour government. The talks broke down when AD's proposal of a coalition running under a separate name, 'Qawsalla', with a new policy platform was rejected by the Nationalists, who were willing to form the coalition only if AD candidates ran under the Nationalist ticket.
