When all that generation had been gathered to their
fathers, another generation arose after them who did
not know the LORD nor the work which He had done
for Israel. Then the children of Israel did evil in the
sight of the LORD, and served the Baals. (Judges 2:10–11)

The Book of Judges provides a vivid biography of leaders, followers, and human nature, and describes a cycle repeated even today:

Rebellion—When things go well, people drop their guard. Peacetime brings a greater chance of rebellion than wartime.

Repression—Repression follows rebellion. Whether God sends an enemy or the people cause their own misery, they endure hardship, calamity, invasion, or natural disaster. Poor life choices result in retribution.

Repentance—Extreme hardships often trigger community–wide repentance. Individuals begin to refocus on what is essential and purify their motives and behaviour. Organizations cut budgets, downsize, and check egos.

Restoration—Purification leads to restoration. When people obey God, peace returns to the land once more. And the cycle of fallen human behaviour has run its entire course. The Maxwell Leadership Bible
