Which was the only state to decline the invitation to all thirteen states to meet in philadelphia to consider revising the articles of confederation?

Rhode Island is the only state which refused to send its delegation to constitutional convention held in Philadelphia in 1787 to consider revising articles of confederation. On condition adding a bill of rights, Rhode Island was the thirteenth state to sign and ratify the constitution on May 29, 1790

Rhode Island is America's littlest state, had big independence streak. They were afraid of a new law which was expected to be passed. According to them, it was limiting the power of the federal government instead it would give too much power to the national government.

yes i can of course like what is it gonna be about

since most of current immigration into the u.s., both legal and illegal, is coming from latin america. it would be very difficult to imagine or rationalize a country my fellow citizens are trying desperately to flee into, would pose a threat to my prosperity or freedom. since the u.s. has a long history of intervention, but no record of permanent occupation, i would not feel oppression is the main objective.  

the largest free trade nation, along with the largest gdp in the world wanting to expand it's economic policy on us, and including us, could only be positive. the u.s. government has no interest in, or way of simply forcing american culture on us. and has no track record of it. other nations that adopted american social culture, or "americanization" did so voluntarily, mainly through the choice of allowing american businesses and u.s. citizens to come into their nations, as free operatives.
