Editing Charles Albert of Sardinia (section)

=== Beginning of crisis with Austria ===
In 1840 the [[Oriental Crisis of 1840|Oriental Crisis]], which placed Louis Philippe's France in conflict with the other European great powers, inspired Charles Albert to begin thinking about a program of territorial expansion in the Po valley.<ref name =Piccola-Treccani/> In the same year, a commercial crisis erupted between Turin and Vienna, regarding an old treaty in which the Kingdom of Sardinia undertook not to provide salt to Switzerland. Following the breach of this treaty, Austria increased the customs duty on Piedmontese wine entering Lombardy-Veneto by 100%. Charles Albert's response was to threaten to build a railroad from Genoa to [[Lake Maggiore]], in order to capture the German commerce which sustained the Austrian port of [[Trieste]] for the Ligurian ports.<ref>{{harvnb|Bertoldi|p=201}}</ref>

These were still only minor disputes and diplomatic relations between the two states continued to be generally good, culminating in the magnificent wedding of Charles Albert's eldest son, Victor Emmanuel and [[Adelaide of Austria]], daughter of [[Archduke Rainer Joseph of Austria|Ranier Joseph of Habsburg-Lorraine]], who was the Austrian Viceroy in Lombardy-Veneto and Charles Albert's brother-in-law, since he had married his sister [[Princess Elisabeth of Savoy|Elisabeth]] in 1820. Victor Emmanuel and Adelaide were thus first cousins.
