The reefs were first known to Europeans by the crew of the brig
Rosalia, commanded by Lieutenant John Garland, which was shipwrecked there in 1807.
The Oriental Navigator for 1816 recorded Garland's discovery under the name Rosaretta Shoal, warning that it was “a dangerous shoal, on which the Rosaretta, a prize belonging to his Majesty's ship Cornwallis, was wrecked on her passage from Pisco, in Peru, to Port Jackson, in 1807”. It noted that it was “composed of hard coarse sand and coral”, a description that must have come from Garland's report. It also said that “from the distressed situation of the prize-master, Mr. Garland”, the shoal's extent could not be ascertained, and concluded: “The situation is not to be considered as finally determined”. It cited different coordinates from those given by Garland: 30°10 South, longitude 173°45' East. The reefs were put on the charts by Captain John Nicholson of
LMS Haweis in December 1818 as reported in
The Sydney Gazette 30 January 1819.
Captain H. M. Denham of surveyed the reefs in 1854 and renamed them after the Australian whaler
Minerva which ran aground on South Minerva Reef on 9 September 1829.
Republic of Minerva In 1972, real-estate millionaire Michael Oliver, of the
Phoenix Foundation, sought to establish a
libertarian country on the reefs. Oliver formed a syndicate, the Ocean Life Research Foundation, which had considerable finances for the project and had offices in
New York City and
London. Morris Davis was elected as the President of Minerva. However, the islands were also claimed by Tonga. An expedition consisting of 90 prisoners was sent to enforce the claim by building an artificial island with permanent structures above the high-tide mark. Arriving on 18 June 1972, the Flag of the Tonga was raised on the following day on North Minerva and on South Minerva on 21 June 1972. King
Tāufaʻāhau Tupou IV announced the annexation of the islands on 26 June; North Minerva was to be renamed Teleki Tokelau, with South Minerva becoming Teleki Tonga. In September 1972,
South Pacific Forum recognized Tonga as the only possible owner of the Minerva Reefs, but did not explicitly recognize Tonga's claimed sovereign title. In 1982, a group of
Americans led again by Morris Davis tried to occupy the reefs, but were forced off by Tongan troops after three weeks. According to
Reason, Minerva has been "more or less reclaimed by the sea". ==Territorial dispute==
