It draws readers into the argument and establishes that ideas apply to society.
It emphasizes that the principles involved are universal, not just American.
Explanation:
When the Declaration of Independence was to be written, one of the men involved was Thomas Jefferson who at that time was just a young lawyer. Finishing the draft in a few days, he mentions the prime issues of the country, highlighting the importance of a country to run by itself and not through any form of monarchy. After listing the importance of the various rights that a man needs, he mentions the American colonies towards the end of the declaration's introduction. This delay is probably more tactical than intentional, for it draws the readers into the argument and establishes that ideas apply to society. It also laid emphasis on the principles laid down in the declaration, stating that they are universal and not just an American related issue.
