Despotism is a form of government in which a single entity rules with absolute power. That entity may be an individual, as in an autocracy, or it may be a group, as in an oligarchy. The word despotism means to "rule in the fashion of a despot" and does not necessarily require a singular "despot", an individual.

Despot comes from the Greek despotes, which roughly means "master" or "one with power", and it has been used to translate a wide variety of titles and positions. It was used to describe the unlimited power and authority of the Pharaohs of Egypt, employed in the Byzantine court as a title of nobility, used by the rulers of Byzantine vassal states, and adopted as a title of the Byzantine Emperors. Thus, despot is found to have different meanings and interpretations at various times in history and can not be described by a single definition. This is similar to the other Greek titles basileus and autokrator, which, along with despot, have been used at various times to describe everything from a local chieftain to a simple ruler, king or emperor.

Catherine II, also known as Catherine the Great (Russian: Екатерина II Великая, Yekaterina II Velikaya; German: Katharina die Große), Empress of Russia (2 May [O.S. 21 April] 1729 – 17 November [O.S. 6 November] 1796), was the most renowned and the longest-ruling female leader of Russia, reigning from 9 July [O.S. 28 June] 1762 until her death at the age of 67. She was born in Stettin, Pomerania, Prussia as Sophie Friederike Auguste von Anhalt-Zerbst-Dornburg, and came to power following a coup d'état and the assassination of her husband, Peter III, at the end of the Seven Years' War. Russia was revitalised under her reign, growing larger and stronger than ever and becoming recognised as one of the great powers of Europe.

In both her accession to power and in rule of her empire, Catherine often relied on her noble favourites, most notably Grigory Orlov and Grigory Potemkin. Assisted by highly successful generals such as Pyotr Rumyantsev and Alexander Suvorov, and admirals such as Fyodor Ushakov, she governed at a time when the Russian Empire was expanding rapidly by conquest and diplomacy. In the south, the Crimean Khanate was crushed following victories over the Ottoman Empire in the Russo-Turkish wars, and Russia colonised the vast territories of Novorossiya along the coasts of the Black and Azov Seas. In the west, the Polish-Lithuanian Commonwealth, ruled by Catherine's former lover, king Stanisław August Poniatowski, was eventually partitioned, with the Russian Empire gaining the largest share. In the east, Russia started to colonise Alaska, establishing Russian America.
