There are 33 traditional noble titles in the modern Kingdom of Tonga.
Twenty titles were established by Siaosi Tupou I with the Constitution of 1875.
Sālote Tupou III created the title of Tupoutoʻa in 1921.
Some of the great chiefs who missed out on a noble's title (in 1910) were among others: ʻAlipate Mafileʻo of Kolomotuʻa, SA Sipu of Kolomotuʻa, Iki Lolohea of Haʻapai (but later inherited the Fulivai), Tēvita Tapueluelu of Vavaʻu, SF Tafolo, Tēvita Ula Afuhaʻamango of Vavaʻu, Siosiua Niutupuʻivaha Kaho (but later inherited the Tuʻivakanō).
In the 21st century, King George Tupou V created eight new noble titles but with no hereditary lands.
