Mata'afa Faumuina Fiame Mulinu'u I was a high chief of Samoa and a leader of the country's pro-independence Mau movement during the 1920's and 1930's. He was the holder of high-ranking ali'i chiefly titles: the Tama-a-'aiga Mata'afa, Fiame from Lotofaga and Faumuina from Lepea.

The Mau was a non-violent movement for Samoan independence from colonial rule during the first half of the 20th century. Mau means ‘resolute’ or ‘resolved’ in the sense of ‘opinion’, ‘unwavering’, ‘to be decided’, or ‘testimony’; also denoting ‘firm strength’ in Samoan. The motto for the Mau were the words Samoa mo Samoa. Similarly in Hawaiian Mau means to strive or persevere, and is often linked with Hawaiian poetry relating to independence and sovereignty struggles.
