The New Mosque (Jamaa-el-Jedid), dating from the 17th century, is in the form of a Greek cross, surmounted by a large white cupola, with four small cupolas at the corners.
Accordingly it was decided to form troops known as nizam-i-jedid, affiliated to the Janissaries so as to disarm the jealousy of the latter, properly drilled and wearing a distinctive uniform.
The remnants of the abolished new troops were collected and formed into regiments affiliated to the Janissaries under the name of seymen-i-jedid; the dignitaries of state were called upon to take an oath of fidelity and loyalty.
The humane and tolerant measures provided for in the " nizam-i-jedid," or new regulations for the better treatment of the Christians enacted by Mustafa Kuprili during his grand vizierate (1689-1691), did for a time improve the position of the rayas.
To the visitor from Europe the attraction of Tunis lies in the native city, where, in the Rue al Jezira, along which runs electric trams, he can see hundreds of camels in the morning bearing charcoal to market; where he may witness the motley life of the bazaars, or, by the Bab-Jedid, watch the snake-charmers and listen to the Moorish storytellers.
Selim profited by the respite to abolish the military tenure of fiefs; he introduced salutary reforms into the administration, especially in the fiscal department, sought by well-considered plans to extend the spread of education, and engaged foreign officers as instructors, by whom a small corps of new troops called nizam-i-jedid were collected and drilled.
