Answer:
The Preamble to the United States Constitution is the introductory statement of the principles that are dealt with in the full text. Within the Preamble, there are many words such as Order, Union, Welfare, Liberty, Justice, etc. that would not be capitalized nowadays. However, the founding fathers decided to start these words with an upper case letter in an attempt to place even more value on the principles that are the cornerstone of the US Constitution.
