King Solomon's massive construction program—the Temple, his palace, fortifications, and cities—imposed heavy taxation and forced labor (corvée) on the Israelites. The economic strain and resentment, especially among the northern tribes, eroded loyalty to the Davidic dynasty. When his son Rehoboam refused to lighten the burden, the northern tribes seceded (930 BCE), splitting the kingdom into Israel (north) and Judah (south). Thus, the very projects that symbolized Solomon's glory sowed the seeds of division.
