This article examines diplomatic relations between England and the Italian
duchy of Savoy during the 1620s through the Savoyard ambassador, Alessandro
Scaglia. Historians have generally viewed England's participation in the T
hirty Year's War from an essentially English viewpoint, underplaying as a r
esult the critical importance of the Anglo-French and Anglo-Spanish wars to
Savoy. The article argues that Scaglia drew upon dynastic affinities betwe
en the Stuart and Savoyard ruling families and on his own qualities to cult
ivate friends at the English court, principally the duke of Buckingham. The
se friends, in turn, increased Scaglia's influence which established him as
a leading mediator in England's wars. This was crucial in providing levera
ge against France and Spain in Savoy's sphere of territorial interest in no
rth Italy. The article shows how this strategy ultimately broke down with r
econfiguration in English foreign policy following Buckingham's death, and
the impact this had on the war for Mantua and Monferrat in north Italy.
