Fortress Masada

Year 73 (LXXIII) was a common year starting on Friday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Domitianus and Catullus (or, less frequently, year 826 Ab urbe condita). The denomination 73 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Events

By place

Roman Empire

• Spring – The Roman governor Lucius Flavius Silva lays siege to Masada, the last outpost of the Jewish rebels following the end in 70 of the First Jewish-Roman War (Jewish Revolt). The Roman army (Legio X Fretensis) surrounds the mountain fortress with a 7-mile long siege wall (circumvallation) and built a rampart of stones and beaten earth against the western approach. After the citadel is conquered, 960 Zealots under the leadership of Eleazar ben Ya'ir commit mass suicide when defeat becomes imminent.
• Pliny the Elder serves as procurator in Hispania Tarraconensis.
• Titus Flavius Domitianus becomes Roman Consul.
• Emperor Vespasian begins conquest of territory east of the upper Rhine and south of the Main. In addition, he reorganizes the defenses of the upper and lower Danube.

Asia

• February – The Chinese Han Dynasty launches a major campaign against the Xiongnu, whom they confront in the Battle of Yiwulu in the Kumul oasis, an ultimate Han military victory led by General Dou Gu (d. 88).
• Ban Chao (Pan-Ch’ao), competing with the Xiongnu, imposes a Chinese protectorate on the kings of Lop Nor and Khotan in the Tarim basin, with the aim of controlling the Silk Road.
