During the 1880s, many gold prospectors came to Ushuaia following rumors of large gold fields, which proved to be false. On 12 October 1884, as part of the South Atlantic Expedition, Commodore Augusto Lasserre established the sub-division of Ushuaia, with the missionaries and naval officers signing the Act of Ceremony. Don Feliz M Paz was named Governor of Tierra del Fuego and in 1885 named Ushuaia as its capital. In 1885 the territory police was organized under Antonio A. Romero with headquarters also in Ushuaia. But it was not until 1904 that the Federal Government of Argentina recognized Ushuaia as the capital of Tierra del Fuego.
