Why did Tycho Brahe leave the island of Ven in 1597?

Tycho Brahe left the island of Ven in 1597 primarily because his influence waned following the death of his patron, King Frederick II, in 1588. Under the reign of the king's son, Christian IV, Tycho faced significant challenges: most of his financial support was withdrawn, partly due to the state's increasing need for funds.1

Furthermore, Tycho had become increasingly demanding regarding his income while simultaneously neglecting the civic duties associated with his state-granted lands. These factors placed him at odds with the three major powers of the time—the king, the church, and the nobility—eventually leading to the withdrawal of his fief and his departure from the island.12
