How is this map different from a typical map of the united states?

i couldn't get the map to paste here but it is of the eastern united states with all the states names crossed out and irish names put in. circa 1900's

i think it was during the potato famine when irish immigrants were arriving in the united states in large numbers and people then thought the united states would be overrun by the irish and the names of everything would be changed to irish namnes.

The correct answer to this open question is the following.

The map is different from a typical map of the United States in that it is a cartoon, depicting the East Coast states of the country, but instead of having the correct US states names on it, it has the names of Irish provinces. Even the name of the Gulf of Mexico and the Atlantic Ocean have Irish names.

I have attached the image for better understanding.

Yes, the Irish Potatoe Famine was a reason for Irish people to emigrate to the United States and they were looking for jobs and better living conditions for their families. So American citizens saw this amount of Irish immigrants coming and feared that they would take many jobs that belonged to U.S. citizens.  

a social contract.

"a social contract is an agreement between citizens and their leader where the citizens give up certain freedoms in exchange for protection. the constitution of the united states is an example of a social contract."
