Gaafu Dhaalu corresponds to the Southwestern section of this large natural atoll, south of the line extending between the channels of Footukandu and Vaarulu Kandu.

(including Gaafu Dhaalu) are code letters assigned to the present administrative divisions of the Maldives.

In January 1959, the three southern atolls: Huvadhu, Fuvahmulah and Addu, were involved in setting up the breakaway United Suvadive Republic which survived until September 1963.

In some islands, like Gaddhū, there was opposition to the secession, and by means of threats and arson, the groups of people opposing the Suvadive state were forced to agree.

Havaru Thinadhoo was burnt down by soldiers sent by then Prime Minister Ibrahim Nasir from Malé during the secession in 1962, after which it was left uninhabited for four whole years.
