Abstract
Leibniz was born near the conclusion of the chaotic period of the Thirty Years War. He studied law and then spent much of his life in the service of nobility and royalty, particularly the House of Hanover that assumed the British Crown a few years before his death. Best known for his works on metaphysics, mathematics, and logic, Leibniz's extensive political correspondence and writings concerned the foundations of law, local and international political affairs and social problems, and moral and political philosophy.
