The city of Strumica

Strumica is the largest city in southeastern Macedonia, near the Novo Selo-Petrich border crossing with Bulgaria. About 55,000 people live in the region surrounding the city. It is named after the Strumica River which runs through it. The city of Strumica is the seat of Strumica Municipality.

          

According to archeological findings, settlement of the area dates back to 6000–5000 BC: a Neolithic settlement (Stranata) located near the village of Angelci, as well as findings from the Emperor’s Towers site near Strumica, where traces of a prehistoric culture existed from the early 4th to mid 3rd millennium BC were discovered. The area was populated later by the Paionians.

The first mention of the city under the name Astraion is in 181 BC regarding the execution of Demetrius, brother of the Ancient Macedonian king Perseus (179–168 BC), son of Philip V of Macedon (221–179 BC). The name Astraion came from the Paionian tribe called Astrai. In 148 BC the region became a Roman province. In the Roman period the city changed its name to Tiberiopolis, which is evidenced by a marble statue base dedicated to the patron Tiberius Claudius Menon, who lived between the late 2nd and early 3rd century AD.

In the 6th and 7th centuries, the Roman town became subject of Slavic migration. The Strymonites, a Sclavene tribe, adopted their name after the Strymon river (Struma). The Strymonites were independent until the 9th century, followed by a Byzantine reconquest.

Under Ottoman administration, the town was named Ustrumca.

In the 17th century, it became seat of a kadiluk. At about this time, Strumica was visited by the Ottoman travel writers Haji Kalfa (1665) and Evliya Çelebi (1670), who gave a description of the city.

After the II world war Strumica is in the Socialist Republic of Macedonia, one of the republics of Federal Yugoslavia. With the referendum on 8 September 1991, amid the breakup of Yugoslavia, the country became independent under the constitutional name Republic of Macedonia.
