The history of the Australian Army is the culmination of the Australian Army's predecessors and its 120-year modern history. The Army has its origins in the British Army and colonial military forces of the Australian colonies that were formed prior to the Federation of Australia. These were gradually united into federal units between 1899 and 1903; thus forming the beginning of the Australian Army. The colonial forces were combined and formed the basis of the new army, when the Commonwealth of Australia was founded on 1 January 1901. The modern history of the Army began with its founding at the start of the 20th century as the colonial armies were officially united as the Commonwealth Military Forces. In 1916 the title 'Australian Military Forces' was adopted and remained its official name until 1980, after which it became known as the Australian Army.
