How many kings ruled Israel during the United Kingdom period?

During the United Kingdom period, Israel was ruled by three significant kings: Saul, David, and Solomon. This period is often characterized by the consolidation of the Israelite tribes under a unified monarchy, which began with Saul as the first king. Following him, David established a strong kingdom and made Jerusalem its capital, and finally, Solomon, known for his wisdom and the construction of the First Temple, reigned after David.
