Amphipolis was originally a colony of ancient Athenians and was the site of the battle between the Spartans and Athenians in 422 BC. It was later the place where Alexander the Great prepared for campaigns leading to his invasion of Asia in 335 BC. Alexander's three finest admirals, Nearchus, Androsthenes and Laomedon, resided in Amphipolis. After Alexander's death, his wife Roxana and their son Alexander IV were imprisoned and murdered there in 311 BC.
Under the reign of Philip II (359–336 BC), the ancient kingdom of Macedonia, initially at the periphery of classical Greek affairs, came to dominate Ancient Greece in the span of less than 25 years, largely thanks to the character and policies of its king. In addition to utilising effective diplomacy and marriage alliances to achieve his political aims, Philip II was responsible for reforming the ancient Macedonian army into an effective fighting force. The Macedonian phalanx became the hallmark of the Macedonian army during his reign and the subsequent Hellenistic period. His army and engineers also made extensive use of siege engines. Chief among Philip's Thracian enemies was the ruler Kersebleptes, who may have coordinated a temporary alliance with Athens. In a series of campaigns stretching from 356 to 340 BC, Philip II managed to ultimately subjugate Kersebleptes as a tributary vassal, conquering much of Thrace in the process. Philip II also fought against the Illyrian king Bardylis, who threatened Macedonia proper, and against Grabos II and Pleuratus in Illyria (centred in modern-day Albania). In his newly conquered territories, he founded new cities such as Philippi, Philippopolis (modern Plovdiv, Bulgaria), Herakleia Sintike (Pirin Macedonia, Bulgaria), and Herakleia Lynkestis (modern Bitola, North Macedonia).
A tumulus (pl.: tumuli) is a mound of earth and stones raised over a grave or graves. Tumuli are also known as barrows, burial mounds, mounds, howes, or in Siberia and Central Asia as kurgans, and may be found throughout much of the world. A cairn, which is a mound of stones built for various purposes, may also originally have been a tumulus.
Tumuli are often categorised according to their external apparent shape. In this respect, a long barrow is a long tumulus, usually constructed on top of several burials, such as passage graves. A round barrow is a round tumulus, also commonly constructed on top of burials. The internal structure and architecture of both long and round barrows have a broad range; the categorization only refers to the external apparent shape.
The Kasta Tomb (Greek: Τύμβος Καστά), also known as the Amphipolis Tomb (Greek: Τάφος της Αμφίπολης), is the largest ancient tumulus (burial mound) ever discovered in Greece, and by comparison dwarfs that of Philip II of Macedon, father of Alexander the Great, in Vergina.
It is an ancient Macedoniantomb of the last quarter of the 4th c. BC, and is enclosed in the Kasta mound near the ancient city of Amphipolis, Central Macedonia, in northern Greece. The first excavations at the mound in 1964 led to exposure of the perimeter wall, and further excavations in the 1970s uncovered many other ancient remains. The inner tomb was first discovered in 2012 and entered in August 2014.
The Battle of Amphipolis was fought in 422 BC during the Peloponnesian War between Athens and Sparta. It was the culmination of events that began in 424 BC with the capture of Amphipolis by the Spartans.
The Struma or Strymonas (Bulgarian: Струма, romanized: Struma, pronounced[ˈstrumɐ]; Greek: Στρυμόνας, romanized: Strymónas, pronounced[striˈmonas]) is a river in Bulgaria and Greece. Its ancient name was Strymon (Greek: Στρυμών, romanized: Strymṓn, pronounced[stryˈmɔːn]). Its drainage area is 17,330 km (6,690 sq mi), of which 8,670 km (3,350 sq mi) in Bulgaria, 6,295 km (2,431 sq mi) in Greece and the remaining 2,365 km (913 sq mi) in North Macedonia and Serbia. It takes its source from the Vitosha Mountain in Bulgaria, runs first westward, then southward, forming a number of gorges, enters Greece near the village of Promachonas in eastern Macedonia. In Greece it is the main waterway feeding and exiting from Lake Kerkini, a significant centre for migratory wildfowl. Also in Greece, the river entirely flows in the Serres regional unit into the Strymonian Gulf in Aegean Sea, near Amphipolis. The river's length is 415 kilometres (258 miles) (of which 290 kilometres (180 mi) in Bulgaria, making it the country's fifth-longest and one of the longest rivers that run solely in the interior of the Balkans.
