What disarmament conference did Harding sponsor?

President Warren G. Harding did not sponsor a disarmament conference. While he was in office, he did host the Washington Naval Conference (1921-1922), which was a significant international conference focusing on naval disarmament and aimed at reducing tensions between the major powers.

However, the conference was not directly sponsored by Harding, but rather it was initiated by Secretary of State Charles Evans Hughes, who was a key figure in planning and executing the conference. Harding himself was supportive of the conference and played a crucial role in securing the participation of other countries, but it was Hughes who was the primary driving force behind the event.
