Final answer:
The Seneca Falls Convention had the historical effect of advancing the women's rights movement, leading to the eventual passage of the 19th Amendment, which provided women with the right to vote.
Step-by-step explanation:
One specific historical effect of the Seneca Falls Convention was the accelerated momentum of the women's rights movement, particularly in the fight for women's suffrage. The Declaration of Sentiments, drafted at the convention, paralleled the Declaration of Independence, asserting that "all men and women are created equal" and listed grievances that women suffered under the existing societal structures. This document and the discourse from the convention catalyzed action and advocacy that would eventually lead to the passage of the 19th Amendment to the U.S. Constitution in 1920, granting women the right to vote.
