Isaac La Peyrère (French pronunciation: [izak la peʁɛʁ]; 1596–1676), also known as Isaac de La Peyrère or Pererius, was a French-born theologian, writer, and lawyer. La Peyrère is best known as a 17th-century predecessor of the scientific racialist theory of polygenism in the form of his Pre-Adamite hypothesis, which offered a challenge to traditional Abrahamic understandings of the descent of the human races as derived from the Book of Genesis. In addition to this, La Peyrère anticipated Zionism, advocating a Jewish return to Palestine. He moved in prominent circles and was known for his connections to the Prince of Condé and the abdicated Christina, Queen of Sweden. Born to a Huguenot family, possibly of Portuguese Jewish converso or Marrano heritage, La Peyrère was pressured to renounce his views and publicly converted to the Catholic Church towards the end of his life, though the sincerity of this conversion has been questioned.
