Passage: In 1820-1830’s the Ottoman Empire endured a number of strikes which challenged the existence of the country.

The disbandment of the centuries-old Janissary corps by Sultan Mahmud II on 15 June 1826 (Auspicious Incident) was a good deed for the country in the longer term, but it has deprived the country from its army forces for the nearest future. In 1827 the allied Anglo-Franco-Russian fleet destroyed almost all the Ottoman naval forces during the Battle of Navarino. In 1830 Greece becomes an independent state after 10 years of independence war and the Russo-Turkish War of 1828–1829.
