the Greek cities of western Crimea which had been so far been controlled by the city of Chersonesus, whose settlements were destroyed and replaced by Scythian fortresses, and which had lost all its possessions not in its immediate vicinity by the middle of the century, with Kalos Limēn and Kerkinitis being defeated and passing under Scythian control; Pontic Olbia also became a subject of Crimean Scythia, with Skiluris minting there and establishing close ties between it and Scythian Neapolis. Thus, Skilurus ruled over all of central, western and northwestern Crimea save for Chersonesus as well as over a significant section of the north-west of the Pontic region, including Pontic Olbia, where he issued his coins. The Crimean Scythian kingdom also acquired a fleet of its own under Skilurus, thanks to which the Scythian traders were able to independently transport their agricultural products to Mediterranean markets. Although Skilurus continued Scythian hostility against Chersonesus, he maintained good ties with the Bosporan kingdom, with a daughter of his marrying a member of its royal dynasty who was named Hērakleidēs. The Crimean Scythians continued participating in the political conflicts on the Bosporan kingdom until Chersonesus requested the assistance of the Pontic Kingdom. Diophantus, the general of the Pontic king Mithridates VI Eupator, allied with Chersonesus and defeated the Crimean Scythian king, Palacus, the son of Skilurus, some time around 110 to 108 BC, after three campaigns. Diophantus captured all the Crimean Scythian fortresses, including the capital of Scythian Neapolis, thus ending the kingdom of the Crimean Scythians and annexing its territory to the Kingdom of Pontus. This intervention saved Chersonesus, although the city was never able to regain all of its territories lost to the Crimean . The Crimean Scythian kingdom nevertheless continued to exist even after its defeat, and, following Mithridates's own defeat by the Roman Republic, the Crimean Scythians were able to regain some of their strength during the 1st century AD, and besieged Chersonesus, who asked help from Rome, and attacked the Bosporan Kingdom. In 64 AD, the Roman legate of Moesia, Tiberius Plautius Silvanus Aelianus, campaigned against the Scythians, defeated them, and installed Roman garrisons in Crimea, including in Chersonesus. By this time, the Crimean Scythians were called "Tauro-Scythians" because of the significant mingling between the Crimean Scythians and the Tauri which had been under way since the 3rd century BC. By 50 to 150 AD, most of the Scythians
