HMS Beagle was a Cherokee-class 10-gun brig-sloop of the Royal Navy, one of more than 100 ships of this class. The vessel, constructed at a cost of £7,803, was launched on 11 May 1820 from the Woolwich Dockyard on the River Thames. The ship took part in celebrations of the coronation of King George IV.
The second voyage of HMS Beagle is notable for carrying the recently graduated naturalist Charles Darwin around the world. While the survey work was carried out, Darwin travelled and researched geology, natural history and ethnology onshore. He gained fame by publishing his diary journal, best known as The Voyage of the Beagle and his findings played a pivotal role in the formation of his scientific theories on evolution and natural selection.
