The Amorite heads depicted at Karnak above the names of the places captured by Shishak in Judah show how little the population of southern Palestine had changed up to the time of Solomon's death.
Canaan was ruined by its want of union.

The Canaanitish cities were perpetually fighting with one another; even the strong hand of the Pharaoh in the days of Egyptian supremacy could not keep them at peace.
Now and again, indeed, they united, generally under a foreign leader, but the union was brought about by the pressure of foreign attack, and was never more than temporary.

There was no lack of patriotism among them, it is true; but the patriotism was confined to the particular city or state to which those who were inspired by it belonged.

The political condition of Canaan resembled its religious condition; as each district had its separate Baal, so too it had its separate political existence.
If there were many Baals, there were also many kinglets.
The fourteenth century B.C.was a turning-point in the history of Canaan.

It witnessed the fall of the Egyptian supremacy which had succeeded the supremacy of Babylonia; it also witnessed the severance of western Asia from the kingdoms on the Euphrates and Tigris, and the consequent end of the direct influence of Babylonian culture.
