Colusi County existed as a legal entity for only a few years after its creation in 1850. It was named after two Mexican land grants; Coluses (1844) and Colus (1845). The name of the county in the original state legislative act was spelled Colusi, and often in newspapers was spelled Coluse. The word is derived from the name of an Indian tribe living on the west side of the Sacramento River. Its name soon changed. Colusi became Colusa on legal documents in 1854 when the county seat moved from Monroeville to Colusa. Two years later the upper third of its territory, along with land from Shasta County on the north, and Butte County on the east, became Tehama County. Red Bluff soon replaced Tehama as the county seat. In 1891, the northern half of Colusa County became Glenn County with Willows as its seat of county government.

The area that once was Colusi shares at least three common geographical features, all traversing the three counties in a north to south direction: the Coast Range Mountains on the west, flat plains in the middle and the Sacramento River on the east. During the past two to three thousand years, its waters has sustained the lives of those, both ancient and contemporary, living along its banks. The River gives humans water to drink and food to eat. It even allows them to swim or to boat upon its surface. For about fifty years, from 1850 to 1900, men, in their steamboats, used it as the major means of transportation.

The River has a Jekyll and Hyde life of its own. It changes with the seasons from a gentle life-sustaining friend of summer and fall to a life taking fiendish flood of winter and spring. Despite the expertise and technology of modernism, its sometimes-uncontrollable rampages still invoke fear and cause catastrophic losses.

American settlement in Colusi-land began very slowly in the 1840's under Mexican rule. The hordes attracted by the discovery of gold bypassed this area. As the work of mining gold increased, disgruntled miners sought other means of support. Some came to old Colusi and took up land along the River or in the foothills of the Coast Range Mountains. Small farms and ranches became common. Settlements became towns. The raising of cattle and sheep gave way to fields of barley and wheat. Steamboats on the Sacramento River brought cargo and passengers to Colusa. Oxen or mule drawn wagons carried supplies and food from there to the mines of Shasta and Trinity Counties.

In 1875, the railroad began its slow advance from Woodland up the treeless, grassy plains, about halfway between the foothills of the Coast Range Mountains and the Sacramento River. It took a half dozen years to reach Red Bluff. As it progressed, it started towns: Arbuckle, Williams, Maxwell, Willows and Orland.

The railroad brought people. Civil War veterans of both the Union and the Confederacy, immigrants from Europe and families from the Mid-west came and found a home in the land of Colusi. Often they purchased a small farm or orchard: almonds in Arbuckle, oranges in Orland, prunes in Colusa, or olives in Corning. Farming changed. Rice and tomatoes surpassed the production of cattle and wheat.

The rapid proliferation of autos that began early in the Twentieth Century made paved roads and highways a necessity. Eventually the building of Interstate 5 parallel to the railroad forged another bond between the counties of Colusa, Glenn and Tehama, the descendants of the original county of Colusi.
