Giovan Giacomo Barbiano di Belgioioso

Giovan Giacomo Barbiano di Belgioioso or Belgiojoso (1565–1626) was an Italian commander in Habsburg service in the Low Countries and the Kingdom of Hungary.

In 1584 Belgioioso went to the Low Countries to join the Army of Flanders with the express purpose of fighting against the enemies of the Catholic Faith.

In 1598 he was appointed commissioner general of cavalry, and in 1601 he was named a councillor of war by Archduke Albert.

[1] In 1603 Rudolf II employed Belgioioso as captain general of imperial troops in Hungary.

He was so shaken by the death of his brother Francesco in 1605 (killed in a quarrel with another imperial commander, Hermann Christof von Russwurm) that he eventually resolved to retire from active service.
