What is a dominion state?

Dominion States

Dominion status was formally defined in the Balfour Declaration of 1926, which recognised these countries as "autonomous Communities within the British Empire", thus acknowledging them as political equals of the United Kingdom.
Dominions were semi-independent polities under the British Crown, constituting the British Empire, beginning with Canadian Confederation in 1867.They included Canada, Australia, New Zealand, Newfoundland, South Africa, and the Irish Free State, and then from the late 1940s also India, Pakistan, and Ceylon (now Sri Lanka). The Balfour Declaration of 1926 recognised the Dominions as "autonomous Communities within the British Empire", and the 1931 Statute of Westminster granted them full legislative independence.
