Hetmancy and Treaty of Andrusovo Poland withdrew from the
right-bank Ukraine due to numerous peasant and cossack uprisings, whose rebels sought to secure their liberties with military support from countries other than Poland and Moscow. They found it in the realm of the
Ottoman Empire, the
Crimean Khanate. In the beginning the first Hetman recognized by Crimea was Sotnyk (captain) Stepan Opara from the Medvedesky company. However, that same summer of 1665 he was replaced by Doroshenko. In order to strengthen his new position, Doroshenko introduced reforms in hope of winning the respect of the rank and file Cossacks. Doroshenko would often organize general councils where he would listen to the lower classes' opinions. And in order to rid himself of the dependence on the starshyna (senior officers), the hetman created the
Serdiuk regiments which consisted of 20,000 mercenary infantry units who took orders only from him. however in the fall of 1667 he lost the
Battle of Podhajce. After the battle, Doroshenko's opposition, led by the Kosh Otaman
Ivan Sirko and Tatars stopped his further advance against Poles. Sukhoviy challenged Doroshenko, but he was defeated at the battle of Olkhivets Soon after the Poles recognized his hetmancy, Khanenko and
Jan Sobieski launched a massive invasion onto the right bank.
War campaign against Poland and Russia In 1672, with a force of 12,000 Doroshenko aided the 100,000 strong
Ottoman Army which invaded
Poland, defeating the Polish army at the battle of Chertvenivka According to the terms of the treaty, the
Podolia voivodeship was turned into an Ottoman province. And the
Bratslav Voivodeship and the southern portion of the
Kiev Voivodship were to be recognized as Cossack territory administered by Doroshenko under a Turkish protectorate. Meanwhile, in summer of 1672, Demian Mnohohrishny was replaced by
Ivan Samoylovych at the 1672 Cossack general council near
Konotop. As the right bank faced devastation by the Turkish power, Doroshenko began to lose the respect of his previously loyal civilians because of his collaboration with the "hated
infidels." Although the alliance did perform an integral part in his successes, the rest of the population suffered at the hands of the Turks. As his forces were weakened from the ongoing wars, Doroshenko was forced to rely increasingly on the Ottomans. This was very unpopular with the majority of deeply
Orthodox Christian Cossacks. At the 1674 Council of Officers in Pereyaslav (17 March) Samoylovych was proclaimed the Hetman of all Ukraine. In the summer of 1674 Samoylovych, along with the Russian
voivode Grigory Romodanovsky launched an
expedition against Doroshenko and besieged Chyhyryn. in
Chyhyryn Doroshenko abdicated and pledged his allegiance to Russia, with
Ivan Sirko witnessing it. However, the Russian government demanded him to abdicate again, on the territory of
left-bank Ukraine, and it should be witnessed by Samoylovych and Romodanovsky, the request of which Doroshenko refused. In the fall of 1676 Samoylovych crossed
the Dnieper with an army of 30,000 men and once again besieged Chyhyryn. After several hours of battle Doroshenko asked his 2,000 Serdiuk garrison to lay down their arms as he had decided to abdicate, which he did on 19 September 1676. Doroshenko was arrested and brought to
Moscow where he was kept in honorary exile, never to return to Ukraine. == Service for Russia ==
