Why did the british participate in the crimean war?

at first they did not want to allow russians to capture Constantinopol because it would strengthen Russia too much.

In Britain, the Crimean War is principally remembered for three reasons: the Charge of the Light Brigade, maladministration in the British army, and Florence Nightingale. However, this war, fought by an alliance of Britain, France, Turkey and Sardinia against Russia, is far more complex.

b. major john c. frémont led a rebellion called the bear flag revolt.

explanation:

during the bear flag revolt, from june to july 1846, a small group of american settlers in california rebelled against the mexican government and proclaimed california an independent republic. the republic was short-lived because soon after the bear flag was raised, the u.s. military began occupying california, which went on to join the union in 1850. the bear flag became the official state flag in 1911.
