Bohemia had an area of and today is home to approximately 6.5 million of the Czech Republic's 10.5 million inhabitants. Bohemia was bordered in the south by Upper and Lower Austria (both in Austria), in the west by Bavaria and in the north by Saxony and Lusatia (all in Germany), in the northeast by Silesia (in Poland), and in the east by Moravia (also part of the Czech Republic). Bohemia's borders were mostly marked by mountain ranges such as the Bohemian Forest, the Ore Mountains, and the Krkonoše, a part of the Sudetes range; the Bohemian-Moravian border roughly follows the Elbe-Danube watershed.
