On 8 April, 1783, Russian Empress Catherine II signed the decree “On Accession of the Crimean Peninsula, the Taman Island and the Kuban Region to the Russian Empire.” Everyone was due to maintain the document in secrecy until the integration became a fait accompli.
On 28 June, 1783, the Manifesto was finally promulgated as the Crimean nobles swore allegiance to the Empress in the presence of Russian Prince Grigory Potemkin. This ceremony was held on top Ak-Kaya.
