During the Neolithic age, Bukovina was populated by the Cucuteni-Trypillian culture of early settlers (4500 BC – 3000 BC), which was overrun around 2000 BC by the migration of Indo-Europeans.
Starting with the 2nd millennium BC, it was inhabited by the Dacian tribes, such as Costoboci and Carpians, and for a period, cohabitated by the Celto-Germanic tribe of Bastarnae. From approx. 70 BC to 44 BC, the region was incorporated in the Dacian polity of Burebista.
When the Dacian Kingdom of Decebal, which included the territories just on the other side of the Carpathian Mountains from what is today Bukovina, fell to the Romans in 106, the area came under linguistic and cultural influence of the Roman Empire.
In the 3rd century (240s–270s) the region was plundered by the Goths, in the 4th century by the Huns (370s–380s), and in the 6th century (560s–570s) by the Avars.
Beginning with the 6th century, Slavic populations entered the region and influenced the language and agricultural methods (e.g. burning the forests to increase the cultivated land) of the locals.
In 797 the Avars, who settled in today’s Hungary and collected regular tribute from the peasants all over southeastern Europe, were defeated by Charlemagne.
According to medieval Kievan sources, until the 10th century the territory had been part of White Croatia and later under the Kievan Rus’, and in 12th to early 14th century, Kingdom of Galicia–Volhynia included parts of the region.
The villages of the Campulung Valley formed a “republic” that preserved its autonomy even under the Principality of Moldavia, which acquired independence in 1359.
In the mid-14th century, the Moldavian state appeared, eventually expanding its territory all the way to the Black Sea. Bukovina and neighboring regions were the nucleus of the Moldavian Principality, with the city of Suceava as its capital from 1388 (after Baia and Siret). The name of Moldavia (Moldova) is derived from a river (Moldova River) flowing in Bukovina.
According to legend, the Boian village was founded by a forester raising oxen (Boi in Romanian) in a glade. In the Middle Ages, trade route linking Cernăuţi (now Chernivtsi) with Iaşi passed through the village. The village is first officially attested in a document dated January 4, 1523 by Stefanita Voievod, ruler of Moldavia. Later the Boian estate is given as a wedding gift to Ion Neculce’s mother, Catrina Cantacuzino, together with Cernauca and 21 other villages.

The Austrian Empire occupied Bukovina in October 1774. Following the first partition of Poland in 1772, the Austrians claimed that they needed it for a road between Galicia and Transylvania. Bukovina was formally annexed in January 1775. On 2 July 1776, at Palamutka, Austrians and Ottomans signed a border convention, Austrians giving back 59 of the previously occupied villages, and remaining with 278 villages.
Bukovina was a closed military district (1775–1786), then the largest district, Kreis Czernowitz (after its capital Czernowitz) of the Austrian constituent Kingdom of Galicia and Lodomeria (1787–1849), and, finally, on 4 March 1849, became a separate Austrian Kronland ‘crown land’ under a Landespräsident (not a Statthalter, as in other crown lands) and declared Herzogtum Bukowina (nominal duchy, as part of the official full style of the Austrian Emperors). In 1860 it was again amalgamated with Galicia, but reinstated as a separate province once again 26 February 1861, a status that would last until 1918.
In this period Boian has become one of the largest villages in Bukovina. They were built three churches and a synagogue, two public schools and one private. At the end of the 19th century several families decided to emigrate to Canada.
