Moldavia

From World travel guide

Moldavia, was a medieval principality on the lower Danube river which, along with Wallachia, formed the basis for the modern Romanian state. Its name originates from the Moldova river.

The principality in its greatest extent streched from Transylvania in the west to the Dniester River in the east, but had its nucleus in the northwestern part, the Ţara de Sus ("Upper Land"), which later became known as Bukovina. This area contained Suceava, the capital of the principality from 1359-1565. Iaşi was the capital from 1565-1859.
