Best Answer: The 16th, 17th, 18th, and 19th amendments called the Progressive Amendments because they were ratified during the progressive era. National Supremacy means national law takes precedence over state law.In other words, all federal laws are superior to any conflicting state or local laws.he 16th established a national income tax, a progressive income tax. The 17th amendment made the people directly elect the Senators, which robbed the states of their power over the federal government.
The 19th Amendment to the U.S. Constitution was finally approved by the houses and ratified by the states on August 18, 1920. The fact that women in the United States were not allowed to vote or speak in the Congress until 1920 clearly answers the question as to why the 19th Amendment was important.he Nineteenth Amendment was a major landmark in the history of the US Constitution. Finally put into action in as many as 36 US states by August 16, 1920, the 19th Amendment changed the face of the electorate of the US forever.
