The archaeological evidence shows a widespread collapse of Bronze Age civilization in the eastern Mediterranean world during the same period, as the great palaces and cities of the Mycenaeans were destroyed or abandoned. Around this time, the Hittite civilization suffered serious disruption and cities from Troy to Gaza were destroyed. Following the collapse, fewer and smaller settlements suggest famine and depopulation. In Greece the Linear B writing of the Greek language used by Mycenaean bureaucrats ceases. The decoration on Greek pottery after ca 1100 BC lacks the figurative decoration of Mycenaean ware and is restricted to simpler, generally geometric styles. It was previously thought that all contact was lost between foreign powers during this period, yielding little cultural progress or growth; however, artifacts from excavations at Lefkandi on the Lelantine Plain in Euboea show that significant cultural and trade links with the east, particularly the Levant coast, developed from c 900 BC onwards, and evidence has emerged of a migration of Hellenes to sub-Mycenaean Cyprus and the Syrian coast (at Al Mina).
