“And The World Rushed In,? the title of historian J.S. Holliday's wonderful book about California, aptly describes what happened after gold was discovered at Sutter's Mill in 1848. Virtually all the Argonauts came to California in quest of wealth. A few came to California for other reasons. David Colbraith Broderick was one. California's pastoral and idle nature under the Spanish/Mexican rule came to an abrupt end after Mexico ceded California to the U.S. pursuant to the Treaty of Guadalupe Hidalgo, the pact executed a few weeks before John Marshall fished out the first gold nuggets from the creek. If only Mexico had known. The transition from Mexican to American rule left a political and legal void in the territory until Californians adopted a state constitution. The political landscape was fertile and virtually unplowed, ripe for planting. Broderick arrived in January 1849, with the will, ambition and skill to sow the political seeds that would grow into one of California's most powerful forces prior to the Civil War.
