The First World War represented the biggest challenge and a test of cohesion for the individual parts of the Empire. Newly, the dominions were to reach full recognition as autonomous nations of the imperial community.
Participation of the Dominions at the Paris Peace Conference and the issues discussed there influenced the status of the Dominions not only to their mother country, but also to the wider world. All the Dominions, except for Newfoundland, found themselves among members of the new international organisation - the League of Nations.
In addition, Dominion delegates also signed the Treaty of Versailles, which the overseas leaders considered a formal recognition of their formal independence on the part of the British. However, in contrast to the expectations of the Dominion representatives, a symbolic recognition of their new status did not take place and, therefore, the world continued to regard them as an integral part of the British Empire, i.e. that the British still represented them in many aspects on the outside.
The course of the conference, however, did confirm that it was not possible to view the Dominions as "ordinary" colonies or dependent territories anymore. The First World War strengthened the general trend heading towards a broader understanding of autonomy and to a more intense cooperation within the Empire.
