Al-Ḥākim's father had intended the eunuch Barjawan to act as regent until Al-Ḥākim was old enough to rule by himself. Ibn 'Ammar and the Qadi Muhammad ibn Nu'man were to assist in the guardianship of the new caliph. Instead, al-Hasan ibn 'Ammar (the leader of the Kutama) immediately seized the office of wasīta "chief minister" from 'Īsa ibn Nestorius. At the time the office of sifāra "secretary of state" was also combined within that office. Ibn 'Ammar then took the title of Amīn ad-Dawla "the one trusted in the empire". This was the first time that the term "empire" was associated with the Fatimid state.
Napoleon invaded Prussia with 180,000 troops, rapidly marching on the right bank of the River Saale. As in previous campaigns, his fundamental objective was to destroy one opponent before reinforcements from another could tip the balance of the war.

At the twin battles of Jena and Auerstedt, fought on 14 October, the French convincingly defeated the Prussians and inflicted heavy casualties. With several major commanders dead or incapacitated, the Prussian king proved incapable of effectively commanding the army, which began to quickly disintegrate.

Lastly, over 360 kilometres (220 mi) to the south of Mafeking lay the diamond mining city of Kimberley, which was also subjected to a siege. Although not militarily significant, it nonetheless represented an enclave of British imperialism on the borders of the Orange Free State and was hence an important Boer objective. The Siege of Kimberley took place during the Second Boer War at Kimberley, Cape Colony (present-day South Africa), when Boer forces from the Orange Free State and the Transvaal besieged the diamond mining town. The Boers moved quickly to try to capture the area when war broke out between the British and the two Boer republics in October 1899.
