Who were the missionaries that tried to convert the Cayuse to Christianity?

The missionaries who attempted to convert the Cayuse people to Christianity were primarily members of the Oregon Mission, notably Marcus and Narcissa Whitman. They arrived in the Oregon Territory in 1836 and established a mission near present-day Walla Walla, Washington. Their efforts faced significant challenges, including cultural differences and resistance from the Cayuse, which ultimately contributed to tensions that culminated in the Whitman Massacre in 1847.
