Third Sacred War
The Third Sacred War (356–346 BC) was fought between the forces of the Delphic Amphictyonic League, principally represented by Thebes, and latterly by Philip II of Macedon, and the Phocians. The war was caused by a large fine imposed in 357 BC on the Phocians by the Amphictyonic League (dominated at that moment by Thebes), for the offense of cultivating sacred land; refusing to pay, the Phocians instead seized the Temple of Apollo in Delphi, and used the accumulated treasures to fund large mercenary armies. Thus, although the Phocians suffered several major defeats, they were able to continue the war for many years, until eventually all parties were nearing exhaustion. Philip II used the distraction of the other states to increase his power in northern Greece, in the process becoming ruler of Thessaly. In the end, Philip's growing power, and the exhaustion of the other states, allowed him to impose a peaceful settlement of the war, marking a major step in the rise of Macedon to pre-eminence in Ancient Greece.
Third Servile War
The effects of the Third Servile War on Roman attitudes towards slavery, and on the institution of slavery in Rome, are harder to determine. Certainly the revolt had shaken the Roman people, who "out of sheer fear seem to have begun to treat their slaves less harshly than before." The wealthy owners of the latifundia began to reduce the number of agricultural slaves, opting to employ the large pool of formerly dispossessed freemen in sharecropping arrangements. With the end of Augustus' reign (27 BC - 14 AD), the major Roman wars of conquest ceased until the reign of Emperor Trajan (reigned 98–117 AD), and with them ended the supply of plentiful and inexpensive slaves through military conquest. This era of peace further promoted the use of freedmen as laborers in agricultural estates.
