William Taylor (1821–1902) was an American Methodist missionary reverend, who in 1884 was elected by the Methodist General Conference as bishop over the Methodist missions in Africa for the Methodist Episcopal Church. Taylor spent most of his adult life performing missionary work around the world. He began his missionary service when he was assigned by the Conference to establish missions in California and provide services in San Francisco during the California gold rush of 1849. His other missionary work involved the establishment of self-supporting missions in various countries about the world, bringing him to England, Ireland, India, South America, Australia, New Zealand and Africa, all of which he wrote about in a number of publications. After many years serving as a Methodist missionary Taylor was elected Bishop of Africa. He has received acclaim and is noted for introducing Methodism through his missionary efforts to several countries around the world. Taylor is also credited for introducing the eucalyptus tree to California with seeds he gathered while serving as a missionary in Australia.

The California gold rush (1848–1855) was a gold rush that began on January 24, 1848, when gold was found by James W. Marshall at Sutter's Mill in Coloma, California. The news of gold brought approximately 300,000 people to California from the rest of the United States and abroad. The sudden influx of gold into the money supply reinvigorated the American economy; the sudden population increase allowed California to go rapidly to statehood in the Compromise of 1850. The Gold Rush had severe effects on Native Californians and accelerated the Native American population's decline from disease, starvation, and the California genocide.
