131
Year 131 (CXXXI) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Laenas and Rufinus (or, less frequently, year 884 Ab urbe condita). The denomination 131 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.

Roman Empire
Emperor Hadrian builds the city Aelia Capitolina on the location of Jerusalem.
The Praetor's Edict is definitively codified by Salvius Julianus on Hadrian's orders. This change means that senatorial decrees become a mere confirmation of the imperial speech (oratio principis) which initiated them.
Reorganization of the Imperial Council: Central administration is reinforced, and administrative positions are entrusted to Knights according to a very strict hierarchy. Under the reorganization, the Roman Senate is excluded from controlling the business of state.
