The declaration of independence stated that the united states was free from spain

The Declaration of Independence ratified on 4th July 1776, stated that the United States was free from its colonial masters, Great Britain, not Spain.

The declaration was written in the midst of the American Revolutionary War of 1775 to 1783 between these 13 colonies and Great Britain; the United States eventually won. To commemorate the importance of the declaration of independence, the United States celebrates their independence day every 4th of July.

the thirteen colonies are:

connecticut, delaware, georgia, maryland, massachusetts, new jersey, new york, new hampshire, north carolina, pennsylvania, rhode island, south carolina, virginia
