Psalms 112

Saul, David, and Solomon. A rare window when both Egypt and Mesopotamia are weak, which is how a small kingdom in the corridor between them could briefly become a regional power.

The power vacuum

This is the whole political explanation for the united kingdom. Egypt is fragmented, Assyria is recovering but still local, the Hittites are gone, and nobody is in a position to object to a strong state in the corridor. It lasts about a century, and Israel's golden age fits exactly inside it.

Phoenicia

Tyre under Hiram is the commercial power of the coast, and supplies the cedar, the craftsmen, and the shipping for Solomon's building programme. The alliance is trade, not charity: Israel had grain and a land route, Tyre had timber and ships.

Egypt

Weak enough that a pharaoh gives a daughter in marriage to an Israelite king, which is the opposite of Egyptian practice in stronger centuries. Late in the era it recovers under a new house, and Shishak will invade within five years of Solomon's death.

Further afield

Greece is still in its dark age but beginning to recover, and will adopt the Phoenician alphabet within a century or two. Carthage is founded by settlers from Tyre by tradition in 814 BC. In the Americas the Olmec centre shifts to La Venta.
