Year 552 (DLII) was a leap year starting on Monday (link will display the full calendar) of the Julian calendar. The denomination 552 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.
- July 1 – Battle of Taginae: Narses crosses the Apennines with a Byzantine army (25,000 men). He is blocked by a Gothic force under king Totila near Taginae (Central Italy). In a narrow mountain valley, Narses deploys his army in a "crescent shaped" formation. He dismounts his Lombard and Heruli cavalry mercenaries, placing them as a phalanx in the centre. On his left flank he sends out a mixed force of foot and horse archers to seize a dominant height. The Goths open the battle with a determined cavalry charge. Halted by enfilading fire from both sides, the attackers are thrown back in confusion on the infantry behind them. The Byzantine cataphracts (Clibanarii) sweep into the milling mass. More than 6,000 Goths, including Totila, are killed. The remnants flee, and Narses proceeds to Rome, where he captures the city after a brief siege.
