Sultan Abdulhamid I acceded the throne, while the Ottoman-Russian war was still continuing. The Ottoman government signed the treaty of Kucuk Kaynarca in order to end the war, in 21^st of July, 1774. By this treaty, Crimea gained liberty. Russia gained legal right for trading in the Black Sea, moreover, Russia began to keep a navy in the Black Sea. The orthodox groups in the Balkans began to be protected by Russia. The Ottoman Empire had accepted to pay war compensation to Russia, and Russia had accepted to give back Wallachia, Moldavia, Beserabya, and the island in the Mediterranean Sea to the Ottomans. But, in these regions the Ottoman government would have forgiven all the criminals and would have not collected taxes. Immigration would be free.

Kucuk Kaynarca was the most repressive treaty that the Ottomans signed. Crimea was the first federation that the Ottoman Empire was completely lost. Turkish domination in the Black Sea had ruined. For the first time the Ottomans paid war compensation to another country. Russia were given capitulation, as well. Moreover, Russia had begun to interfere the Ottoman Empire’s internal issues.
