<u><em>16th Amendment:</em></u>
The 16th Amendment to the United States Constitution establishes that Congress shall have power to collect taxes on income, without apportionment among the states and without regard to any census or enumeration.
Before the 16th amendment was passed, The United States had to rely on tariffs in order to raise revenue. This reliance would have made it impossible for the country to implement a free trade system. As it was ratified in February 3rd, 1913, it also made it much easier to fund WWI.
