In what year did Kentucky become the 15th state to join the union?
Explanation
Kentucky became the 15th state to join the Union in 1792. This significant year marks Kentucky's admission into the United States as a fully recognized and independent state. After being part of Virginia as a county, Kentucky's rapid growth, population, and desire for self-governance led to its separation and subsequent statehood. The state's fertile land, abundant natural resources, and strategic location played a crucial role in its early development and acceptance into the Union, solidifying Kentucky's place in American history.
