9. In 1392, a wild boar killed the widely-loathed Robert de Vere, Duke of Ireland
King Richard II’s favorite, Robert de Vere, backed the wrong horse. He loyally attempted (and failed) to defeat Richard’s enemies, a group of nobles who dominated the English government. In 1387, after defeat at Radcot Bridge, he fled to the continent, where a wild boar killed him near Louvain. This had dire consequences for Richard. Robert’s death left him completely at the mercy of the aptly-named Merciless Parliament. Parliament curtailed Richard’s power, and relentlessly bullied him. His reign never recovered. After being deposed as king by Henry Bolingbroke he starved to death while imprisoned at Pontefract Castle in 1400.
