Manifest Destiny

An Introduction

American FlagNo nation ever existed without some sense of national destiny or purpose.

Manifest Destiny – a phrase used by leaders and politicians in the 1840s to explain continental expansion by the United States – revitalized a sense of "mission" or national destiny for Americans.

The fledgling nation's first attempts at creating a new government included placing the country under the rule of an emperor. In 1824, the monarchy was overthrown and a constitutional republic was formed. But internal struggles between the various political factions, such as the Centralist, Federalist, Monarchist and Republican parties, drained even more of the country's energy and resources. These political factions were not united and new struggles broke out by the different sides as each tried to secure dominant rule.

Mexico won vast northern territories with its independence from Spain. These borderlands were underpopulated, so amid its internal political struggles and economic deficits, Mexico was also challenged to colonize these territories and guard its borders. Protecting and colonizing Mexico's northern territories proved to be nearly impossible for the staggering country:
