Why did Giordano Bruno leave Paris in 1586?

Giordano Bruno left Paris in 1586 primarily because he had lost the support of the Politiques, the moderate Catholic faction that had previously protected him.12

Upon his return to Paris in 1585, the political climate had shifted; King Henry III had revoked the edict of pacification with the Protestants, and the king of Navarre had been excommunicated. Despite this volatile environment, Bruno engaged in public polemics against a protégé of the Catholic party and, in May 1586, launched a public attack on Aristotle in his work Centum et viginti articuli de natura et mundo adversus Peripateticos. Following this provocation, the Politiques disavowed him, leading to his departure from the city.2
