Curiosity got this cat. I knew a filibuster was was like a mercenary or someone engaging in unauthorized warfare against a foreign country. The military context of filibuster. So I was wondering how filibuster became associated with the U.S. Senate as a way to prolong debate, avoiding a vote on legislation. Here's what I found.
Using the filibuster to delay debate or block legislation has a long history. The term filibuster, from a Dutch word meaning "pirate," became popular in the United States during the 1850s when it was applied to efforts to hold the Senate floor in order to prevent action on a bill.https://www.senate.gov/reference/Index/Filibuster.htm
And here for JGW.https://www.senate.gov/about/powers-procedures/filibusters-cloture.htm
So it seems unlimited debate was allowed in the senate from 1789 until 1917 when the cloture rule was established as a means to end debate and move to a vote.Actually the filibuster is nothing more than a right for unlimited debate.
Interesting also in the United States House of Representatives, the filibuster (the right to unlimited debate) was used until 1842, when a permanent rule limiting the duration of debate was created.
I didn't know that.
