Nur Jehan took good care of her own family. Her father continued to occupy the office of grand vizier until his death, and her brother, Asaf Khan, became high treasurer of the empire and father-in-law of the Mogul. Other relatives were placed in remunerative and influential positions. But at last she made a blunder, and failed to secure the crown for her son, Sheriar, who, being a younger member of the family, was not entitled to it, and Shah Jehan, the oldest son of the Mogul by another wife, succeeded him to the throne. Shah Jehan promptly murdered his ambitious brother, as was the amiable custom of those days, but treated his father's famous widow with great respect and generosity. He presented her with a magnificent palace, gave her an allowance of $1,250,000 a year and accepted her pledge that she would interfere no longer in politics. She survived nineteen years and devoted her time and talents thereafter and several millions of dollars to the construction of a tomb to the memory of her father, which still stands as one of the finest of the group of architectural wonders of Agra. It is situated in a walled garden on the bank of the River Jumna about a mile and a half from the hotels, and is constructed entirely of white marble. The sides are of the most beautiful perforated work, and the towers are of exquisite design. Much of the walls are covered with the Florentine mosaic work similar to that which distinguishes the Taj Mahal. [Illustration: AKBAR, THE GREAT MOGUL. SHAH JEHAN]
