The filibuster, which began in 1789, was the most important legal battle in American history.
It was a fight between two men who were both willing to use their influence over Congress to stop government from spending money on anything that was not the state’s prerogative.
The filibuster was a simple but powerful tactic that, through decades of abuse and overuse, led to the abolition of the US Senate.
The filibuster was an important political tool that could change the course of history.
But the filibuster has been in the news for many years.
We take a look back at some of the most significant filibusters of the 20th century, including the 1798 Senate vote to end slavery and the 1796 Senate vote that forced President Grover Cleveland to resign from office.
Next up, in the 19th century: the filibuster in the US military.
Next week, we look at the 1797 Supreme Court case that would lead to the first presidential filibuster.
And we look ahead to the 2020 elections.
