What was Edmund Barton's political party?

Edmund Barton led the Protectionist Party.

With the backing of the Protectionists, Barton embarked on a campaign to deal with the problems of Australian defence, the creation of courts to adjudicate on industrial relations and the Constitution (he later sat as one of the founding Justices in the newly-formed High Court of Australia). He also worked towards a unified tariff system and the White Australia Policy which seemed to be what many Australians wanted.
