As per the California Indian History, The tribes of Natives lived in California for an estimated to be more than 15,000 years. Various estimates of native population during pre-european times are range between 100,000 to 300000. The earliest Californians were believed to be Asians who moved across the Bering Straits to Alaska, which was thousands of years ago during the time of harsh climates through the land bridge made such travel easier which the route is is now vanished. California's which is vastly with mountain ranges and deserts, made difficult for indigenous groups to travel great distances and native people are isolated from region to region tending in large family groups unlike the tribes in the eastern United States. The mountain ranges of the pacific coast isolated these early settlers from the cultures that developed in neighboring Mexico and the western parts. California tribes used to be lived comparatively peaceful life, The early population of California of these plains and apparently shared no ties of language or culture with other nations. the original Californians were a diverse people, separated by language and culture and into as many as 135 distinct dialects. During pre-european times, "California" means the peninsula on the west coast of modern Mexico now known as Baja California, and the Spanish explorers believed that they had discovered an enormous island. First European explorer Juan Rodriguez Cabrillo from spain started discovering in 1542. The Spanish discovery of California area was one of the great expansions of Spain explorers over extended empire in North America, at this time California was the most densely populated in the United States before the arrival of europeans. From 1770 to 1798 Various Missions are established like Carmel misssion, San Gabriel mission, San Luis Obispo, San Fransisco, San Buenaventura, Santa Barbara, Santa Cruz, San Jose, San Juan Bautista, San Fernando, San Luis Rey missions. Massive Indian revolts among the Pueblo Indians in the late 17th century provided the Franciscan padres with an argument to establish missions relatively free from colonial settlers. These missions were authorized to convert the Indians in the specific period of time. Thereafter they were suppose to surrender their control over the missions livestock, fields, orchards and building to the Indians. But the padres never achieved this kind of goal and apparently the lands and wealth was stolen from the Indians. California and its Spanish Colonization are different from their earlier efforts to simultaneously introduce missionaries and colonists to conqest schemes. But before epidemic diseases proved to be the most crucial factor in Spanish efforts to overcome native resistance, diseases such as smallpox, diphtheria, syphilis and even chickenpox and measles of children ailments caused greater death among Native Indians, in 1806 Measles epidemic and in 1838 Northwest smallpox epidemic killed 3,000, in 1840 Smallpox epidemic in southern territory killed 2,400. A general population was decreased due to unhygenic conditions in the area of colonial centers. By 1806 these epidemics killed thousands of Indians including children. Tribes included the Karok, Maidu, Cahuilleno, Mojave, Yokuts, Pomo, Paiute, and Modoc. 1848 Gold was discovered, in 1849 Miners begin to encroach into Indian territories and in 1851 Mariposa Indian War, Huge numbers of Indians slaughtered in gold country and Karuk villages are burned by Whites in 1852. By 1924, Indian Citizenship Act was created and Indians given right to vote.
