The us entered world war 1 on April 6, 1917
The answer is allowing privileges such as freedom of the press<span />
Well if we are talking about the United States than:
We have the Bill Of Rights
but before that we had the articles of confederation which was the original constitution of the US, ratified in 1781,Which we receive guiding principles from Britain. Articles of Confederation was replaced by the US Constitution in 1789.
Hope that helps!<span />
