Catherine II (born Princess Sophia Augusta Frederica, Russian: Екатерина Алексеевна Романова; 2 May 1729 – 17 November 1796), commonly known as Catherine the Great, was the reigning Empress of Russia from 1762 to 1796. She came to power after a coup d'etat against her husband, Peter III. Her long reign helped Russia thrive under a golden age under the Enlightenment. This renaissance led to the founding of many new cities, universities, and theatres, along with large-scale immigration from the rest of Europe and the recognition of Russia as one of the great powers of Europe.After overthrowing and possibly assassinating her husband and her subsequent rule of the Russian Empire, Catherine often relied on noble favourites such as Count Grigory Orlov and Grigory Potemkin. Assisted by highly successful generals such as Alexander Suvorov and Pyotr Rumyantsev and admirals such as Samuel Greig and Fyodor Ushakov, she governed at a time when the Russian Empire was expanding rapidly by conquest and diplomacy. In the west, she installed her former lover to the throne of Poland, which was eventually partitioned. In the south, the Crimean Khanate was annexed following victories over the Bar Confederation and the Ottoman Empire in the Russo-Turkish War. With the support of Great Britain, Russia colonised the territories of New Russia along the coasts of the Black and Azov Seas. In the east, Russians became the first Europeans to colonise Alaska, establishing Russian America..
