Is the western frontier expansion the same thing as the westward expansion someone plz help

Westward expansion: the 19th-century movement of settlers into the American West, began with the Louisiana Purchase and was fueled by the Gold Rush, the Oregon Trail and a belief in "Manifest Destiny."

Western Frontier expansion: with European colonial settlements in the early 17th century and ended with the admission of the last few territories as states in 1912. This era of massive migration and settlement was particularly encouraged by President Thomas Jefferson following the Louisiana Purchase, giving rise to the expansionist attitude known as "Manifest Destiny"

So saying that I would guess that they are many names for the same thing. They also both refer to "Manifest Destiny".

for the united states of america, 1945 to 1964 was a time of high economic growth and general prosperity. it was also a time of confrontation as the capitalist united states and its allies politically opposed the soviet union and other communist countries; the cold war had begun.
