The established merchants and plantation operators in the African colonies frequently managed to sway government policies. Capital investments by banks were secured with public funds of the imperial treasury to minimize risk. Dernburg, as a former banker, facilitated such thinking; he saw his commission to also turn the colonies into paying propositions.
