We mark certain days of the year with ‘On This Day’ posts, recalling events associated with them.

Our events are grouped under two calendars. The Gregorian ‘New Style’ (NS) is the worldwide calendar first issued at Rome in 1582. On that calendar, today is January 10. The Julian ‘Old Style’ (OS), also issued at Rome but in 46 BC, was used in Roman Britain and then in England from Anglo-Saxon times until 1752. It is still used today by roughly 100 million Orthodox Christians worldwide. On that calendar, today is December 28.

Caesar Crosses the Rubicon

When Julius Caesar defied the Senate’s explicit order to resign his military command, he knew there could be no turning back.

Success in the Gallic Wars (58-51 BC) made Julius Caesar, the great Roman general, a popular hero to the Republic. His bitter rival in the Senate, Pompey, found him increasingly difficult to handle, but on January 1st, 49 BC, Pompey managed to get the Senate to overrule the tribune Gaius Scribonius Curio, who had been blocking him at every turn, and require that Caesar lay down his military command.
