Year 70 (LXX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Augustus and Vespasianus (or, less frequently, year 823 Ab urbe condita). The denomination 70 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.
By place 
Roman Empire 
- Emperor Vespasian and his son Caesar Vespasian (the future emperor Titus) become Roman Consuls.
- Panic strikes Rome as adverse winds delay grain shipments from Africa and Egypt, producing a bread shortage. Ships laden with wheat from North Africa sail 300 miles to Rome's port of Ostia in 3 days, and the 1,000 mile voyage from Alexandria averages 13 days. The vessels often carry 1,000 tons each to provide the city with 8,000 tons per week it normally consumes.
- Sextus Julius Frontinus is praetor of Rome. Legio II Adiutrix is created from marines of Classis Ravennatis.
- Pliny the Elder serves as procurator in Gallia Narbonensis.
- April 14 – Siege of Jerusalem: Titus surrounds the Jewish capital, with three legions (V Macedonica, XII Fulminata and XV Apollinaris) on the western side and a fourth (X Fretensis) on the Mount of Olives to the east. He puts pressure on the food and water supplies of the inhabitants by allowing pilgrims to enter the city to celebrate Passover and then refusing them egress.
- May 10 – Titus opens a full-scale assault on Jerusalem, he concentrates his attack on the city's Third Wall (HaHoma HaShlishit) to the northwest. The Roman army tries to breach the wall using testudos, mantlets, siege towers, and battering rams.
- May 25 – The Third Wall of Jerusalem collapses and the Jews withdraw from Bezetha to the Second Wall, where the defences are unorganized.
- May 30 – Titus and his Roman legions breach the Second Wall of Jerusalem. The Jewish defenders retreats to the First Wall. The Romans built a circumvallation, all trees within fifteen kilometres of the city are cut down.
- July 20 – Titus storms the Fortress of Antonia north of the Temple Mount. The Romans are drawn into street fighting with the Zealots.
- August 4 – Titus destroys the Jewish Temple in Jerusalem. Roman troops are stationed in Jerusalem and abolish the Jewish high priesthood and Sanhedrin. This becomes known as the Fall of Jerusalem, a conclusive event in the First Jewish-Roman War (the Jewish Revolt), which began in 66 AD. Following this event, the Jewish religious leadership moves from Jerusalem to Jamnia (present day Yavne), and this date is mourned annually as the Jewish fast of Tisha B'Av.
- August–September – Titus assaults the Temple Mount and destroys Herod's Palace in the Upper City of Jerusalem. Jewish resistance ends on September 26.
