Events

Under the command of Punicus and then Cesarus, the Lusitani, a Hispanic tribe, reach a point near modern day Gibraltar. Here they are defeated by the Roman praetor Lucius Mummius.

As part of the Roman efforts to fully conquer and occupy the whole of Illyria, a Roman army under consul Publius Cornelius Scipio Nasica Corculum attacks the Dalmatians for the first time and conquers the Dalmatian capital of Delminium. As a result, the Dalmatians are compelled to pay tribute to Rome, which puts and end to the first Dalmatian war. In recognition of his victory, Corculum is granted a triumph in Rome.

Menander I (known as Milinda in Sanskrit and Pali) begins his reign as king of the Indo-Greek Kingdom. His territories cover the eastern dominions of the divided Greek empire of Bactria (Panjshir and Kapisa) and extend to the modern Pakistani province of Punjab, most of the Indian states of Punjab and Himachal Pradesh and the Jammu region. His capital is considered to have been Sagala, a prosperous city in northern Punjab believed to be modern Sialkot.
