Henry Berengar
Henry Berengar (born 1136 or 1137, died 1150) was the eldest son of King Conrad III of Germany and Gertrude of Sulzbach, groomed for the succession. Before leaving on the Second Crusade, Conrad had the princes elect the ten-year-old Henry co-king at Regensburg in March 1147, and he was crowned at Aachen.
He led the royal army to victory over Welf VI and Welf VII at the Battle of Flochberg in 1150. He died later that year and was buried at Lorch, predeceasing his father.
