El Dorado and Union County

The history of Union County is about the land and its people, from the first settlers to those who marched off to war. It is also about a seismic shift from a sleepy small town supported by farming and timber to a great boomtown with the striking of oil in 1921. Thousands of people poured in, and the area would never be the same again, with the impact spanning the next century. Even after the great heady days of the oil boom were in the past, Union County and El Dorado would diversify their industry for the future.
