The Continental Group during the Nazi period

This study is the first to comprehensively examine the development of the Continental rubber and tire company during the Nazi period using sources that have recently become available. It shows to which extent Continental developed into a model Nazi operation within the scope of the National Socialist autarky, armaments, and war economy and analyzes how it dealt with foreign workers and activities in occupied, allied, and neutral countries.
