Why was Otto von Bismarck reluctant to build a German colonial empire?

Otto von Bismarck was long opposed to establishing a German colonial empire primarily because he believed Germany already faced sufficient geopolitical risks within Europe. He sought to avoid challenging the established imperial interests of major powers like Great Britain and France, which he feared would jeopardize the security of the newly unified German state.1

Bismarck’s primary objective was to maintain peace and stability in Europe, and he viewed overseas expansion as a potential source of unnecessary conflict. His reluctance was rooted in his political conservatism; he was anxious to arrest German expansionism to prevent Germany from dominating Europe, which he believed would threaten the empire's survival. When he eventually pursued colonial acquisitions, it was often a calculated diplomatic maneuver—such as attempting to create friction between Britain and France—rather than a genuine desire for an overseas empire. Ultimately, he viewed the colonies as an embarrassment and a drain on resources rather than a source of national strength.1
