970 CE
The oldest preserved document (by Otto I) mentions Leibnitz in Styria (modern Austria). Emperor John I delegates the war in the Balkans to his brother-in-law, the Domestic of the Schools Bardas Skleros, and to the eunuch general Peter Phokas, who begin to gather a Byzantine army in Thrace. At the news of this, a powerful Kievan expeditionary force (30,000 men), along with many Bulgarians and a Pecheneg contingent, is sent south over the Balkan Mountains. After sacking the Bulgarian stronghold of Philippolis (modern-day Plovdiv), they bypass the heavily defended city of Adrianople, and turn towards Constantinople. Construction is completed on Al-Azhar Mosque in Cairo, Egypt (the world's oldest Islamic university).
