The country underwent a struggle for political independence in the early 1900s, organised under the aegis of the national Mau movement. During this period, the streets of Apia were the site of non-violent protests and marches, in the course of which many Samoans were arrested. On what became known as "Black Saturday" (28 December 1929), during a peaceful Mau gathering in the town, the New Zealand constabulary killed the paramount chief Tupua Tamasese Lealofi III.
