What led to the fall of the ghanian empire?

The Ghana Empire crumbled from the 12th century CE following drought, civil wars, the opening up of trade routes elsewhere, and the rise of the Sosso Kingdom (c. 1180-1235 CE) and then the Mali Empire (1240-1645 CE).

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.
