Samuel Wilbore was one of the founding settlers of Portsmouth in the Colony of Rhode Island and Providence Plantations. He emigrated from Essex, England to Boston with his wife and three sons in 1633. He and his wife both joined the Boston church, but a theological controversy began to cause dissension in the church and community in 1636, and Wilbore aligned himself with John Wheelwright and Anne Hutchinson, signing a petition in support of dissident minister Wheelwright. In so doing, he and many others were disarmed and dismissed from the Boston church. In March 1638, he was one of 23 individuals who signed a compact to establish a new government, and this group purchased Aquidneck Island, then known as "Rhode Island", from the Narragansett Indians at the urging of Roger Williams, establishing the settlement of Portsmouth.

Stephen Arnold Douglas was an American politician and lawyer from Illinois. A senator, he was one of two nominees of the badly split Democratic Party for president in the 1860 presidential election, which was won by Republican candidate Abraham Lincoln. Douglas had previously defeated Lincoln in the 1858 United States Senate election in Illinois, known for the pivotal Lincoln–Douglas debates. He was one of the brokers of the Compromise of 1850 which sought to avert a sectional crisis; to further deal with the volatile issue of extending slavery into the territories, Douglas became the foremost advocate of popular sovereignty, which held that each territory should be allowed to determine whether to permit slavery within its borders. This attempt to address the issue was rejected by both pro-slavery and anti-slavery advocates. Douglas was nicknamed the "Little Giant" because he was short in physical stature but a forceful and dominant figure in politics.
