Which state was formed from land that was part of the Louisiana Purchase -- Missouri or Pennsylvania?

The state that was formed from land that was part of the Louisiana Purchase is Missouri. The Louisiana Purchase, which occurred in 1803, involved the acquisition of a vast territory from France, effectively doubling the size of the United States at that time. This territory encompassed a significant portion of land west of the Mississippi River, including what would later become several states.

Missouri was officially admitted to the Union in 1821 as part of this land. Its location directly along the western edge of the states that made up the original United States, and its boundary with the Mississippi River, positions it firmly within the area that was obtained through the Louisiana Purchase.

In contrast, Pennsylvania was one of the original thirteen colonies and was not part of the land acquired through the Louisiana Purchase. Other states like Arkansas and Kansas were indeed part of the Louisiana Purchase; however, the question specifically asked about the formation of the state, and Missouri is the state that fits this historical timeline of becoming a state from that acquired land. Thus, Missouri is the correct answer.
