Antonino Paternò Castello, Marchese di San Giuliano

In his younger years he studied economics and sociology, and published articles on agriculture, industry, population, labour legislation, and emigration in various journals.

[1] In 1882 he was elected to parliament and aligned himself with Sidney Sonnino, representing the conservatives who identified with the old Historical Right.

[1] He conducted a policy of friendship toward France, while remaining faithful to Italy's commitments to Austria-Hungary and the German Empire.

He resisted the expansion of Austria-Hungary in the Balkans, supported Italian economic penetration of Montenegro, and the independence of Albania.
