Why did the sardinians participate in the crimean war? they wanted to assist their allies, the russians. they wanted to control the black sea. they wanted to win support from britain and france for a united italy. they wanted to protect christian interests in the ottoman empire.

The correct answer is:

They wanted to win support from Britain and France for a united Italy.

Sardinia provided help to the British and the French with an expeditionary brigade of 15,000 soldiers as a means to guarantee their cooperation in the unification of Italy.

The Italian troops in the Crimea War proved their power in the Battle of the Chernaya (16 August 1855) and in the siege of Sevastopol, allowing the Kingdom of Sardinia to be a part of the peace conference at the end of the war to discuss the issue of the Risorgimento with the European powers.
