The Duchy of Bukovina (; ; ) was a constituent land of the Austrian Empire from 1849 and a Cisleithanian crown land of Austria-Hungary from 1867 until 1918. Name The name Bukovina came into official use in 1775 with the region's annexation from the Principality of Moldavia to the possessions of the Habsburg monarchy (which became the Austrian Empire in 1804, and Austria-Hungary in 1867). The official German name, die Bukowina, of the province under Austrian rule (1775–1918), was derived from the Polish form Bukowina, which in turn was derived from the Ukrainian word, Буковина (Bukovyna), and the common Slavic form of buk, meaning beech tree (бук [buk] as, for example, in Ukrainian or, even, Buche in German). Another German name for the region, das Buchenland, is mostly used in poetry, and means "beech land", or "the land of beech trees". In Romanian, in literary or poetic contexts, the name Țara Fagilor ("the land of beech trees") is sometimes used. In English, an alternative form is The Bukovina, increasingly an archaism, which, however, is found in older literature. History After the Mongol invasion of Europe, the Bukovina lands since the 14th century had been part of the Principality of Moldavia, with Suceava being the princely capital from 1388 to 1565. In the 16th century, Moldavia came under Ottoman influence, but still retaining its autonomy. During the early 18th century, Moldavia became the target of the Russian Empire's southwards expansion, inaugurated by Tsar Peter the Great during the Pruth River Campaign of 1710–11. In 1769, during the Russo-Turkish War of 1768–74, Moldavia was occupied by Russian troops. Austrian rule Following the First Partition of Poland in 1772, the Habsburg monarchy had aimed at a land connection from the Principality of Transylvania to the newly acquired Kingdom of Galicia and Lodomeria. After the Russo-Turkish Treaty of Küçük Kaynarca was concluded in July 1774, the Austrians entered into negotiations with the Sublime Porte from October and could finally obtain a territory of Moldavia with an area of about 10,000 square kilometres (ca. 4,000 square miles) they called Bukowina, which they formally annexed in January 1775. On 2 July 1776, at Palamutka, Austrians and Ottomans signed a border convention, the Habsburg monarchy giving back 59 of the previously occupied villages, and remaining with 278 villages. For opposing and protesting the annexation of the northwestern part of Moldavia, the Moldavian ruler Prince Grigore III Ghica
