Explanation:

The Pike Expedition (1806-1817) was a military expedition sent by the United States government to explore the recently acquired territory of Louisiana.

In 1803, French emperor Napoleon Bonaparte sold the territory of Louisiana to the United States. This territory was largely unexplored and populated mostly by indigenous tribes. Then president Thomas Jefferson authorized an expedition in 1806 to explore the south and west of the territory, close to the northern border of what was then New Spain (later Mexico). Lt. Zebulon Pike departed with 70 other men on his way to explore the Great Plains and the Rocky Mountains. However, he drifted south, and ended in Spanish territory, where he was captured. He was released shortly after and returned to the United States.

In 1810, Pike wrote a book recounting from his memory his expeditionary exploits. The book was immensely popular - it was later translated into French, German and Dutch.
