• Friedrich Magnus II (1806–1857) • Friedrich Magnus III (1857–1883) • Friedrich Magnus IV (1883–1910) • Friedrich Magnus V (1910–1945), married
Princess Marie Antoinette of Schwarzburg, who presumably became the head of the
House of Schwarzburg in 1971. Following
her brother's death in 1971 in the House of Schwarzburg became extinct in the male line. However the Schwarzburg principalities operated under
Semi-Salic primogeniture which means that in the event of the extinction of all male dynasts, as happened with the death of Prince Friedrich Günther, females can inherit. • Friedrich Magnus VI (1945-) : upon
his mother's death in 1984, Friedrich Magnus VI inherited a claim to the headship of the
House of Schwarzburg under
semi-Salic law. == References ==
