The story deals with the mysterious period in the life of Sultan Moulay Ismail from his reign to his death. All military, political, economic and architectural achievement (1672/1727).I show in this book the house (Dar Al Kabira) of the caliphate where he was the Sultan and his family. And I realized the plan as it was in 1680! ..I touch in this story, the territorial and military policy of the Sultan by the composition of the army to the question of the European captives, the wars against the Ottomans (the Turco-Algerians) the internal wars against his family and the rebel tribes.As well his conquests in Morocco, religious life in the 17th century and the useful references of the Sultan's policy.
