Final answer:
The NAWSA was founded in 1890, with Carrie Chapman Catt and Anna Howard Shaw advocating for state suffrage reforms and partial support for a constitutional amendment. Alice Paul and Lucy Burns, seeking more immediate action, eventually formed the NWP to pursue a federal amendment through more direct advocacy.
Step-by-step explanation:
The National American Woman Suffrage Association (NAWSA) was founded in 1890 as a result of a merger between two groups led by Elizabeth Cady Stanton and Susan B. Anthony, and Lucy Stone, with differing views on achieving suffrage. Leaders like Carrie Chapman Catt and Anna Howard Shaw favored a more conservative approach and sought suffrage reforms on a state-by-state basis; while they also worked for a constitutional amendment, they largely maintained a moderate stance. On the other hand, radicals like Alice Paul and Lucy Burns lobbied for an immediate federal amendment, separating to form the National Woman's Party (NWP), which used more confrontational tactics such as picketing the White House and staging hunger strikes to draw attention to their cause.
