Until then, Hven had been property directly under the Crown, and the 50 families on the island considered themselves to be freeholding farmers, but with Tycho's appointment as Feudal Lord of Hven, this changed. Tycho took control of agricultural planning, requiring the peasants to cultivate twice as much as they had done before, and he also exacted corvée labor from the peasants for the construction of his new castle. The peasants complained about Tycho's excessive taxation and took him to court. The court established Tycho's right to levy taxes and labor, and the result was a contract detailing the mutual obligations of lord and peasants on the island.
