The French and Indian War, and The American Revolution                                      

Explanation:

The participation of France in the French and Indian War first drained the treasury and later the American Revolution.

France entered into financial crises during the reign of King Louis XV, who dispatched six regiments to New France in 1755 that led to the French and Indian War. France financial situation went further down when they took participation in the American Revolution of 1775. The country was in enormous debt, and it had to increase its taxes.  

in mcculloch v. maryland (1819) the supreme court ruled that congress had implied powers under the necessary and proper clause of article i, section 8 of the constitution to create the second bank of the united states and that the state of maryland lacked the power to tax the bank.

gibbons v. ogden, (1824), was a landmark decision in which the supreme court of the united states held that the power to regulate interstate commerce, granted to congress by the commerce clause of the united states constitution, encompassed the power to regulate navigation.
