Upon arrival in an area occupied by a tribe of natives, the Cossacks entered into peace talks with a proposal to submit to the White Tsar and to pay yasak, but these negotiations did not always lead to successful results. When their entreaties were rejected, the Cossacks elected to respond with force. At the hands of people such as Vasilii Poyarkov in 1645 and Yerofei Khabarov in 1650 some peoples, including the Daur, were slaughtered by the Russians. 8,000 out of a previous population of 20,000 in Kamchatka remained after being subjected to half a century by Cossacks.[7] The Daurs initially deserted their villages since they heard about the cruelty of the Russians the first time Khabarov came.[8] The second time he came, the Daurs decided to do battle against the Russians instead but were slaughtered by Russian guns.[9] In the 17th century, indigenous peoples of the Amur region were attacked by Russians who came to be known as "red-beards".[10]

In the 1640s the Yakuts were subjected to murderous expeditions during the Russian advance into the land near the Lena river, and on Kamchatka in the 1690s the Koryak, Kamchadals, and Chukchi were also subjected to this by the Russians according to Western historian Stephen Shenfield.[11] When the Russians did not obtain the demanded amount of yasak from the natives, the governor of Yakutsk, Piotr Golovin, who was a Cossack, used meat hooks to hang the native men. In the Lena basin, 70% of the Yakut population declined within 40 years, rape and enslavement were used against native women and children in order to force the natives to pay the Yasak.[8][better source needed]

In Kamchatka the Russians savagely crushed the Itelmens uprisings against their rule in 1706, 1731, and 1741, the first time the Itelmen were armed with stone weapons and were badly unprepared and equipped but they used gunpowder weapons the second time. The Russians faced tougher resistance when from 1745-56 they tried to exterminate the gun and bow equipped Koraks until their victory. The Russian Cossacks also faced fierce resistance and were forced to give up when trying unsuccessfully to wipe out the Chukchi through genocide in 1729, 1730-1, and 1744-7.[12] After the Russian defeat in 1729 at Chukchi hands, the Russian commander Major Pavlutskiy was responsible for the Russian war against the Chukchi and the mass slaughters and enslavement of Chukchi women and children in 1730-31, but his cruelty only made the Chukchis fight more fiercely.[13] A genocide of the Chukchis and Koraks was ordered by Empress Elizabeth in 1742 to totally expel them from their native lands and erase their culture through war. The command was that the natives be "totally extirpated" with Pavlutskiy leading again in this war from 1744-47 in which he led to the Cossacks "with the help of Almighty God and to the good fortune of Her Imperial Highness", to slaughter the Chukchi men and enslave their women and children as booty. However the Chukchi ended this campaign and forced them to give up by killing Pavlitskiy and decapitating him.[14] The Russians were also launching wars and slaughters against the Koraks in 1744 and 1753-4.

After the Russians tried to force the natives to convert to Christianity, the different native peoples like the Koraks, Chukchis, Itelmens, and Yukagirs all united to drive the Russians out of their land in the 1740s, culminating in the assault on Nizhnekamchatsk fort in 1746.[15] Kamchatka today is European in demographics and culture with only 2.5% of it being native, around 10,000 from a previous number of 150,000, due to the mass slaughters by the Cossacks after its annexation in 1697 of the Itelmen and Koryaks throughout the first decades of Russian rule. The killings by the Russian Cossacks devastated the native peoples of Kamchatka.[16] In addition to committing genocide the Cossacks also devastated the wildlife by slaughtering massive numbers of animals for fur.[17] 90% of the Kamchadals and half of the Vogules were killed from the eighteenth to nineteenth centuries and the rapid genocide of the indigenous population led to entire ethnic groups being entirely wiped out, with around 12 exterminated groups which could be named by Nikolai Iadrintsev as of 1882. Much of the slaughter was brought on by the fur trade.[18]

According to Western historian James Forsyth, Aleut men in the Aleutians were subjects to the Russians for the first 20 years of Russian rule, as they hunted for the Russians while Aleut women and children were hold as captives as a means to maintain this relationship.[19]

The oblastniki in the 19th century among the Russians in Siberia acknowledged that the natives were subjected to immense genocidal exploitation, and claimed that they would rectify the situation with their proposed regionalist policies.[20]

The Russian colonization of Siberia and conquest of its indigenous peoples has been compared to European colonization in the United States and its natives, with similar negative impacts on the natives and the appropriation of their land.[21] The Slavic Russians outnumber all of the native peoples in Siberia and its cities except in the Republic of Tuva, with the Slavic Russians making up the majority in the Buriat Republic, and Altai Republics, outnumbering the Buriat, and Altai natives. The Buriat make up only 29,51% of their own Republic, and the Altai only one-third; the Chukchi, Evenk, Khanti, Mansi, and Nenets are outnumbered by non-natives by 90% of the population. The natives were targeted by the tsars and Soviet policies to change their way of life, and ethnic Russians were given the natives' reindeer herds and wild game which were confiscated by the tsars and Soviets. The reindeer herds have been mismanaged to the point of extinction.[22]

The Ainu have emphasized that they were the natives of the Kuril islands and that the Japanese and Russians were both invaders.[23] In 2004, the small Ainu community living in Kamchatka Krai wrote a letter to Vladimir Putin, urging him to reconsider any move to award the Southern Kuril islands to Japan. In the letter they blamed both the Japanese, the Tsarist Russians and the Soviets for crimes against the Ainu such as killings and assimilation, and also urged him to recognize the Japanese genocide against the Ainu people, which was turned down by Putin.[24]
