King Sobhuza II's 1973 Coup Against His Own Country's Constitution

Swaziland, now Eswatini, became independent from Britain on September 6, 1968, as a constitutional monarchy with King Sobhuza II as head of state and an elected parliament operating under a British-drafted constitution. That arrangement held for less than five years. In the 1972 general election, Sobhuza’s own Imbokodvo National Movement won decisively, taking 21 of 24 parliamentary seats on 78 percent of the vote, but for the first time an opposition party, the Ngwane National Liberatory Congress, won parliamentary representation at all, taking three seats with just over 18 percent of the vote.

That modest opposition foothold set off a slow-moving constitutional crisis. Days after the election, one of the newly elected Ngwane MPs faced deportation proceedings; he won an initial court challenge, but parliament revoked his citizenship outright in November 1972, a move Swaziland’s own Appeal Court subsequently ruled unconstitutional. Rather than accept that ruling, parliament passed a motion on April 12, 1973, asking the king to “devise ways and means of dealing with the crisis.” Sobhuza’s answer, delivered the same day in a formal proclamation, went well beyond resolving one contested seat: backed by a private royal army he had secretly raised and armed, he suspended Swaziland’s constitution entirely, dissolved parliament, banned all political parties, and declared himself holder of supreme legislative, executive, and judicial authority.

Sobhuza justified the move by arguing that the British-drafted constitution did not reflect authentic Swazi custom or governance, a framing that cast the return to unchecked monarchical rule as a restoration rather than a seizure of power. In practice, it ended parliamentary politics in the country for good: no new constitution followed for years, and when one eventually did, it entrenched rather than limited royal authority, formally placing the king above the law he now ruled by. Sobhuza governed by decree for the rest of his life. He died on August 21, 1982, having reigned for 82 years and 254 days since being crowned king at four months old following his father’s death, the longest verifiable reign of any monarch in recorded history. He spent the final decade of that reign converting a fledgling constitutional monarchy into what remains, to this day, one of the world’s last absolute monarchies.
