Answer:
Nationalism.
A feeling of nationalism developed in the United States after the War of 1812. 
The victories of the US forces in major battles of the 1812 War , particularly in New Orleans (fought after the signing of the peace treaty of Ghent), made Americans proud and joyful.  Peace was welcomed and Americans had a great feeling that they had resisted the power of the British Empire again. The 1812 War is called a "Second Independence War" by some. It fostered a firmer sense of national conciousness. The postwar period led to the Era of Good Feelings in American politics. By going to war over its rights, the nation made sure that it was going to receive proper treatment as an independent nation in the world.

For the benefit of their new settlement, the Mayflower Compact established laws for the settlers that would form a new community and come together to accomplish it. Knowing life without laws could prove disastrous, the Mayflower Compact was established by colonist leaders to ensure a working social system prevailed.
