Professor Custred takes us traveling in three historical borderland regions of what would become the state of California. The Spanish Empire in the New World reached as far north as Sonoma. The vast Russian Empire stretched southward to Ft. Ross. And in an arc to the north, the British Empire, acting through the Hudson Bay Company, sought to extend its influence south of the Columbia River. The rapidly expanding settlement frontier of the United States would, in time, sweep all this away, and California, in the wake of war with Mexico, became a state of the union without even passing through territorial status. But these old borderlands left their traces. Let OLLI and Professor Custred help you explore them.
