The city was destroyed and the remaining 50,000 Carthaginian citizens were sold into slavery. This battle ended the Punic Wars and practically ceded the remainder of Carthage's territory to the Roman Republic.
• 55 B.C Great Britain: The first Roman invasion of Britain took place when Julius Caesar and his legions landed on the British coast but were soon pushed from the area. He would return the following year with a much larger force and made better progress. However, Caesar would ultimately make peace with the British people and the Roman Republic would commence trade with them.^[1] Later Roman invasions would prove more successful.
• 821 Ireland: The first recorded Viking raid in Irish history occurred in AD 795 when Vikings, possibly from Norway looted the island of Lambay. The Viking raids on Ireland resumed in 821, the Vikings began to establish fortified encampments, longports, along the Irish coast and overwintering in Ireland instead of retreating to Scandinavia or British bases. The first known longports were at Linn Dúachaill (Annagassan) and Duiblinn (on the River Liffey, at or near present Dublin).

• 865 Great Britain: The first known account of a Viking raid in Anglo-Saxon England comes from 789, when three ships from Hordaland (in modern Norway) landed in the Isle of Portland on the southern coast of Wessex. From 865 the Norse attitude towards Great Britain changed, as they began to see it as a place for potential colonisation rather than simply a place to raid. As a result of this, larger armies began arriving on Britain's shores, with the intention of conquering land and constructing settlements there. Norse armies captured York in 867.

The colony at L'Anse aux Meadows in Canada and the Maine Penny in the United States are the most reliable proof of Norse presence in America.^{[citation needed]}
