Nabis was ruler of Sparta from 207 BC to 192 BC, during the years of the First and Second Macedonian Wars and the War against Nabis. After taking the throne by executing two claimants, he began rebuilding Sparta's power. During the Second Macedonian War, he sided with King Philip V of Macedon and in return he received the city of Argos. However, when the war began to turn against the Macedonians, he defected to Rome. After the war, the Romans urged by the Achaean League attacked Nabis and defeated him in the War against Nabis. He was assassinated in 192 BC by the Aetolian League and was Sparta's last independent ruler. He represented the last phase of Sparta's reformist period.

The National Ballistics Intelligence Service, or NABIS, is the U.K.'s intelligence service dedicated to managing and providing detailed information regarding firearm-related criminality. The service aims to use its database to store ballistics information about police cases involving firearms, and consequently maintain it for future use and reference. Three new facilities have been created to test and analyse firearms evidence to help link it with other cases. These are based in Birmingham, London and Manchester.
