The Battle of Leuctra shatters Sparta's reputation of military invincibility.
In 371 BC, Thebes defeated Sparta at Leuctra, shattering Sparta’s legendary military invincibility.
In 371 BC, the Theban general Epaminondas led his forces to a decisive victory over the Spartan army at Leuctra. The battle tactics introduced by Epaminondas, such as the oblique formation, caught the Spartans by surprise. This marked the first significant defeat of Sparta in centuries and undermined its status as the dominant military power in Greece.

French Wars of Religion: Siege of La Rochelle ends.
The siege of La Rochelle, a principal action of the French Wars of Religion, concludes in 1573 with the city's royalist defeat.
On July 6, 1573, the seven-month Siege of La Rochelle ended with the surrender of Huguenot forces to King Charles IX's royal army. La Rochelle, a Protestant stronghold on the Atlantic coast, had resisted royal authority since the outbreak of the French Wars of Religion. Under siege by royal cannons and naval blockades, the city suffered famine and disease before falling to the crown. The capitulation reinforced Catholic dominance and weakened the Huguenot movement in France. Although the Peace of La Rochelle granted limited religious freedoms, it marked a turning point in the struggle between Catholics and Protestants. The siege's outcome influenced subsequent conflicts and shaped the religious landscape of France for decades.
