Final answer:
Bismarck strategically created turmoil in Europe to strengthen Prussia which led to German unification, provoked wars such as the Franco-Prussian War, and annexed territories contributing to rising tensions that set the stage for future conflicts.
Step-by-step explanation:
What Otto von Bismarck did to create turmoil in Europe involved a series of strategic and provocative actions aimed at strengthening Prussia and eventually leading to German unification.
By playing European powers against each other, making and breaking alliances, and engaging in wars, Bismarck navigated a complex political landscape to elevate Prussia's position. He instigated the Austro-Prussian War in 1866, under the pretense of controlling the German-speaking territories.
His policies further escalated tensions when he orchestrated the Franco-Prussian War in 1870 by provoking France and alienating potential French allies. This culminated in the German annexation of Alsace-Lorraine, further inflaming Franco-German hostilities which laid the foundation for future conflicts in Europe.
