In addition to being a publisher of personal appeals, Wikipedia is also a vast repository of knowledge. Here’s a sampling:
The Egg War is the name given to an 1863 conflict between rival egging companies on the Farallon Islands, 25 miles off San Francisco. It was the culmination of several years of tension between the (Pacific) Egg Company, which claimed the right to collect the eggs on the islands, and several rival firms. The resulting violence claimed two lives, but left the Egg Company in sole control of the islands’ eggs. Its victory was short lived; the company sold the rights to use the islands in the late 1870s and the federal government removed all egging companies from the islands in 1881.
