Explanation:
WHO: The Oregon Trail was laid by fur traders and trappers from about 1811 to 1840, and was only passable on foot or by horseback. By 1836, when the first migrant wagon train was organized in Independence, Missouri, a wagon trail had been cleared to Fort Hall, Idaho.
What: The Oregon Trail was a 2,170-mile east-west, large-wheeled wagon route and emigrant trail in the United States that connected the Missouri River to valleys in Oregon. The eastern part of the Oregon Trail spanned part of what is now the state of Kansas and nearly all of what are now the states of Nebraska and Wyoming
WHY: Determined to spread Christianity to American Indians on the frontier, doctor and Protestant missionary Marcus Whitman set out on horseback from the Northeast in 1835 to prove that the westward trail to Oregon could be traversed safely and further than ever before.
HOW: Everything from California to Alaska and between the Rocky Mountains and the Pacific Ocean was a British-held territory called Oregon. The trail pointed the way for the United States to expand westward to achieve what politicians of the day called its “Manifest Destiny” to reach “from sea to shining sea.”
