In 1853, Isaac Cody sold his land in rural Scott County, Iowa, for $2000 (around $68,000 in today's money) and the family moved to Fort Leavenworth, Kansas Territory. In the years before the Civil War, Kansas was overtaken by political and physical conflict over the slavery question. Isaac Cody was against slavery. He was invited to speak at Rively's store, a local trading post where pro-slavery men often held meetings. His antislavery speech so angered the crowd that they threatened to kill him if he didn't step down. A man jumped up and stabbed him twice with a Bowie knife. Rively, the store's owner, rushed Cody to get treatment, but he never fully recovered from his injuries.
