Van Diemen's Land was the colonial name of the island of Tasmania during the European exploration and colonisation of Australia in the 19th century. The Aboriginal-inhabited island was first visited by the Dutch ship captained by Abel Tasman in 1642, working under the sponsorship of Anthony van Diemen, the Governor-General of the Dutch East Indies. The British retained the name when they established a settlement in 1803 before it became a separate colony in 1825. Its penal colonies became notorious destinations for the transportation of convicts due to the harsh environment, isolation and reputation for being escape-proof.
The name was changed to Tasmania on 1 January 1856 to dissociate the island from its convict past and to honour its European discoverer, Abel Tasman. The old name had become a byword for horror in England because of the severity of its convict settlements such as Macquarie Harbour and Port Arthur. When the island became a self-governing colony in 1855, one of the first acts of the new legislature was to change its name.
