After the death of Henry IV Sully published, in the deceased king's name, his ‘Grand Design’, a plan to stop the religious wars. His starting point was that the three churches (Catholic, Lutheran and Calvinist) were there to stay. He planned an international organization, consisting of a Europe of 15 more or less equally strong powers, incidentally dissolving the Habsburg empire and thus making France Europe’s strongest state. A balance of power mechanism and a permanent assembly of ambassadors should prevent wars in Europe. Military power would only be needed towards Russia and the Ottoman Empire.
