20th Century
In October 1941, the mayor of Port Orford, Oregon, Gilbert Gable, announced that the Oregon counties of Curry, Josephine, Jackson, and Klamath should join with the California counties of Del Norte, Siskiyou, and Modoc to form a new state, later named Jefferson.
On November 27, 1941, a group of young men gained national media attention when, brandishing hunting rifles for dramatic effect, they stopped traffic on U.S. Route 99 south of Yreka, and handed out copies of a Proclamation of Independence, stating that the state of Jefferson was in "patriotic rebellion against the States of California and Oregon" and would continue to "secede every Thursday until further notice."
The secession movement came to an abrupt end, though not before John C. Childs of Yreka was inaugurated as the governor of the State of Jefferson. The first blow was the death of Mayor Gable on December 2, followed five days later by the attack on Pearl Harbor on December 7. Secessionists focused their efforts on the war effort, which crippled the movement. Coincidentally, the "state of Jefferson" was one of the few places in the continental USA to be the subject of an attack during World War II, when Japanese pilot Nobuo Fujita dropped bombs on the Oregon Coast near Brookings on September 9, 1942.
