Prior to Russian exploration, the peninsula was inhabited by various
Chukotko-Kamchatkan peoples (specifically the
Itelmen,
Koryak, and
Alyutor). The southern tip of the peninsula was also the northernmost extent of
Ainu settlement. When the Russian explorer
Ivan Moskvitin reached the
Sea of Okhotsk in 1639, further exploration was impeded by the lack of skills and equipment to build seagoing ships and by the harsh land to the northeast inhabited by the warlike
Koryak people. Consequently, Russians entered Kamchatka from the north. In 1651, after having assisted in the foundation of the
Anadyrsk ostrog, the explorer
Mikhail Stadukhin went south and followed the coast of the Sea of Okhotsk from
Penzhina Bay to
Okhotsk. From about 1667 there were reports of a Kamchatka River to the south. Some time before 1700,
a group of Russians were stranded and died on Kamchatka. In 1695, explorer
Vladimir Atlasov became commander of Anadyrsk. In 1696, he sent the Cossack
Luka Morozko south. Morozko got as far as the
Tigil River and returned with reports and some mysterious writings, probably Japanese. In 1697–1699, Atlasov explored nearly the whole of the peninsula. He built an
ostrog at Verkhny-Kamchatsk, rescued or captured
a Japanese castaway, and went to Moscow to report. In 1699, the Russians at Verkhny-Kamchatsk were killed on their way back to Anadyrsk by the Koryaks. In 1700, a punitive expedition destroyed a Koryak village and founded Nizhne-Kamchatsk on the lower river. Bolskeretsk was founded in 1703. From about 1705, there was a breakdown of order. There were numerous mutinies and native wars all over the peninsula and north to the Koryak country of the
Penzhina River and
Olyutor Gulf. Several people were sent out to restore order, including Atlasov, who was murdered by mutineers in 1711. Vasily Merlin restored some degree of order between 1733 and 1739. There was no significant resistance after 1756. A major smallpox epidemic that hit in 1768–1769 quickly decimated the native population; the roughly 2,500
Itelmens present in 1773 were reduced to 1,900 in 1820, from an original population of 12,000–25,000. Those who survived adopted Russian customs, and there was a great deal of intermarriage, such that "Kamchadal" (the original Russian name for the Itelmens) came to mean any Russian or part-Russian born on the peninsula. In 1713,
Peter the Great sent shipbuilders to Okhotsk. A fifty-four-foot boat was built and sailed to the Tegil River in June 1716. This one-week journey, later redirected to Okhotsk-Bolseretsk, became the standard route to Kamchatka. In 1720,
Ivan Yevreinov mapped Kamchatka and the Kurils. The Danish-born Russian explorer
Vitus Bering left Nezhe-Kamchatsk for his first voyage in 1728 and, as part of his second voyage, founded
Petropavlovsk-Kamchatsky in 1740. Vitus Bering's
Second Kamchatka Expedition (ca 1733–1743), in the service of the
Russian Navy, began the final "opening" of Kamchatka, helped by the fact that the government began to use the area to exile people, famously the Hungarian nobleman and explorer the
Count de Benyovszky in 1770. In 1755,
Stepan Krasheninnikov published the first detailed description of the peninsula,
An Account of the Land of Kamchatka. The Russian government encouraged the commercial activities of the
Russian-American Company by granting land to newcomers on the peninsula. By 1812, the
indigenous population had fallen to less than 3,200 while the Russian population had risen to 2,500. In 1854, the
French and
British, who were battling Russian forces in the course of the
Crimean War, attacked
Petropavlovsk. During the
Siege of Petropavlovsk, 988 men with a mere 68 guns managed to defend the outpost against 6 ships with 206 guns and 2,540 French and British soldiers. Despite the successful defense, the Russians abandoned Petropavlovsk as a strategic liability after the French and British forces withdrew. The next year, when a second enemy force came to attack the port, they found it deserted. Frustrated, the ships bombarded the city and withdrew. On 24 May 1861, the ship
Polar Star (475 tons), of
New Bedford, wrecked on the west coast of Kamchatka during a dense
fog and
gale. The chief officer and a boat's crew perished while attempting to reach the shore. The rest of the crew were saved by the
barque Alice, of
Cold Spring, and the ship
Oliver Crocker, also from New Bedford. On 21 May 1865, the
American Civil War came to the area: the
Confederate States Navy steamer
Shenandoah sailed past the southern tip of the Kamchatka Peninsula on its way to hunt United States whaling ships in the Sea of Okhotsk. As a
commerce raider, the CSS
Shenandoah aimed to destroy Union merchant shipping and thus draw off United States Navy ships in pursuit, thereby loosening the US Navy blockade of Confederate coasts. The ship spent almost three weeks in the Sea, destroying only one ship due to the dangerous ice, before moving on to the North Pacific, where it virtually captured or bonded 24 whalers, sinking most of them. The next 50 years were lean for Kamchatka. The naval port moved to Ust-Amur, and in 1867, Russia
sold Alaska to the United States, making Petropavlovsk obsolete as a transit point for traders and explorers on their way to the American territories. In 1860, a
Primorsky (Maritime)
Region was established and Kamchatka was placed under its jurisdiction. In 1875, Russia ceded the
Kuril Islands to Japan in return for Russian sovereignty over
Sakhalin island. The Russian population of Kamchatka stayed at around 2,500 until the turn of the century, while the native population increased to 5,000. During the 19th century, scientific exploration of the peninsula continued.
Karl von Ditmar made an important journey to the peninsula in 1851–1854. In 1920, Russian leader
Vladimir Lenin offered a 60-year lease of the peninsula to the United States. World War II (1939–1945) hardly affected Kamchatka except for its role as a launch site for the
invasion of Manchuria in August 1945. After the war, the Soviet authorities declared Kamchatka a military zone. Vilyuchinsk, located on the Kamchatka Peninsula about 20 kilometers (12 mi) across Avacha Bay from Petropavlovsk-Kamchatsky, was founded as Sovetsky in 1968 through the amalgamation of three earlier settlements that supplied the Soviet Navy as a submarine constructor; it remains the home base of the Russian Pacific fleet. The
Kura Missile Test Range, an intercontinental ballistic missile impact area located northeast of the settlement of
Klyuchi, was developed beginning in 1955. Kamchatka remained
closed to unauthorised Soviet citizens until 1989 and to foreigners until 1990. From 1946 to 1949, around 50,000
North Koreans went to Kamchatka as workers. Several thousand refused to repatriate after the end of their contract, which has led to a community of around 1,800 by 2020.
