Biography

Otto was the eldest son of Henry II, Duke of Brunswick-Grubenhagen (c. 1289 – 1351) and Jutta of Brandenburg.

In 1353, he married Violante of Vilaragut, a daughter of Berengar de Vilaragut and widow of James III of Majorca. There were no children from this marriage. By 1372, Otto was a widower. On 25 September 1376, Otto married his second wife, the three times widowed Queen Joanna I of Naples. The groom was fifty-six years old and the bride about forty-eight. The marriage was childless.

The so-called Western Schism started in 1378 with the election of two rival popes, Urban VI of Rome and Clement VII of Avignon. Joanna supported Clement VII and allied herself with his main supporter Charles V of France. With no hope of having further children of her own, Joanna chose to strengthen her alliance with France by adopting Louis of Anjou, younger brother of Charles V, as her heir.

Urban VI proclaimed Joanna deposed in 1381. He named her second cousin Charles of Durazzo as his candidate for the supposedly vacant throne. Charles spent the following months gathering his army within the Kingdom of Hungary and then marched against the Kingdom of Naples. Otto led the Neapolitan army in battle but was defeated. Otto was exiled from Naples by the new king and never returned. On the 27th of July, 1382 at age 56, Joanna was strangled in prison in the Castle of Muro Lucano held by Palamede Bozzuto.

Otto survived Joanna by at least sixteen years but never remarried. He died childless at Foggia and was succeeded by his first cousin, once removed Eric I, Duke of Brunswick-Grubenhagen, previously Duke of Einbeck.
