Answer: Suffrage supporters had the greatest success in states that were in the western United States.
Step-by-step explanation: Wyoming. On December 10, 1869, Territorial Governor John Allen Campbell signed an act of the Wyoming Territorial Legislature granting white women the right to vote, the first U.S. state or territory to grant suffrage to women. Wyoming is in the western Texas. The woman's suffrage movement is important because it resulted in passage of the Nineteenth Amendment to the U.S. Constitution, which finally allowed women the right to vote. The woman suffrage movement has promoted human welfare in numerous ways.
