Cloture--with a 2/3 majority Senate vote a filibuster can be ended.
A filibuster is a long speech meant to block the vote of a bill. Both sides of Congress are able to filibuster and was used regularly starting in the 1850s. However, as the House of Representatives grew, filibustering could prevent anything from getting accomplished in Congress. The Progressive Era set to reform many government procedures and the introduction of cloture by the Wilson administration created a way around a filibuster allowing for Congress to move forward with their business if 2/3 of the chamber voted to end the filibuster.
