During those days, Lange's factorij had trading interests of a million guilders in trade with Java specifically. His success was primarily due to his ability to create personal ties, especially with the local Rajas. The Dutch, who were also trying to set up trade on Bali, were less successful, and in May 1844 they named Lange their agent on the island, with the right to fly the Dutch flag. Now Mads was not just working for himself, but also for the Dutch authorities who profited from his cooperation.
