Flag of Bosnia and Herzegovina of Khotyn in Bukowina. It differs from Ottoman flag by size and direction of crescent, but also it is swallow-shaped, like some West-European jacks and ensigns. In the 1830s revolt by Husein Gradaščević the green flag with a yellow crescent and star was used. The revolt's aim was for Bosnia to gain autonomy from the Ottoman Empire. In 1878 Bosnia existed briefly as an independent nation. Its flag was very similar to the flag used by Husein Gradaščević's revolt of 1830. It was a yellow crescent and star on a green background, with the crescent thinner than the previous flag's.
