International affairs moved along new paths for a substantial time after the war's conclusion. Germany, the rising power of the late nineteenth and early twentieth centuries, was reduced in size and power in the aftermath of World War I. The Treaty of Versailles ended the German overseas empire, and it restricted the size and nature of the German military system. While neighbors such as France and Poland could have armies as large and as well equipped as they wished, Germany was compelled to limit its force to 100,000 men and to renounce the era's most potent weapons, such as the submarine and the combat airplane. The surrender of the great ships of the German navy after the November 1918 Armistice, and their scuttling by their own crews at Scapa Flow on June 21, 1 9 1 9, to prevent them from being transferred to British hands, ended the threat of Germany as a naval power. The territory of imperial Germany was reduced by 15 percent as it lost lands to Belgium, France, Denmark, and Poland. For the next decade and a half, countries along Germany's borders were able to breathe more easily at the sight of their mammoth neighbor reduced to second-rate military status.
