The southeast quadrant of Europe has had an exceedingly involved and complex history, owing in large part to the nature of the land, which is deeply shattered by numerous mountain ranges. Fertile river valleys being set between these mountains, the Balkans have provided many opportunities for ethnic groups to develop in isolation from one another, although nearby in straightline distances. The region has never been completely unified, the closest approximation to this was during Roman Imperial times. What follows is an index to three separate pages, each dealing with a subregion within the Balkans.

Eastern Balkans This covers Bulgaria, Romania, and Moldova, and also has a note on the Huns.

Southern Balkans This has Greece, and Hellenic districts both ancient and Mediaeval.

Western Balkans Currently, this covers Albania and most of Yugoslavia: to wit, Bosnia, Hercegovina, Croatia, Dalmatia, Macedonia, and Serbia.
