 From the early 14th century BC, Mycenaean trade began to take advantage of the new trading opportunities in the Mediterranean after the Minoan collapse. The trade routes were expanded further reaching Cyprus, Amman in the Near East, Apulia in Italy and Spain. At that time (c. 1400 BC), the palace of Knossos yielded the earliest records of the Greek Linear B script, based on the previous Linear A of the Minoans. The use of the new script spread in mainland Greece and offers valuable insight of the administrative network of the palatial centers. However, the unearthed records are too fragmentary for a political reconstruction of Bronze Age Greece.
