The Second School War (French: Deuxième guerre scolaire, Dutch: Tweede schoolstrijd) was a political crisis in Belgium over the issue of religion in education. The conflict lasted between 1950 and 1959 and was ended by a cross-party agreement, known as the School Pact, which clarified the role of religion in the state. It followed a crisis over the same issue in the 19th century, known as the First School War.
