It may be the highest court in the land, one that hugely influences the nation, but only the landmark abortion case, Roe vs. Wade, is known by a majority of Americans, according to a survey released by C-SPAN.

The poll found that of the most significant court decisions ever, 67 percent of 1,200 polled said they were familiar with Roe vs. Wade, which legalized abortion.

In no other case did a majority signal familiarity.

-- 46 percent are familiar with Brown vs. Board of Education, the 1954 decision that struck down the doctrine of "separate but equal."

-- 34 percent are familiar with "Bush vs. Gore," that set the stage for the Bush presidency in 2001.

-- 27 percent are familiar with the 1966 "Miranda vs. Arizona" case resulted in the "Miranda warning."

The poll helped to make the case for why people should tune into C-SPAN's new Landmark Cases series starting Monday that explores the issues, people and places involved in the most historically significant Supreme Court cases.

C-SPAN described their series this way:

Landmark Cases explores the human stories and constitutional dramas behind some of the most significant and frequently cited decisions in the Supreme Court's history. This 12-part series delves into cases that represent some of the tipping points in our nation's story and in our evolving understanding of rights in America.

Produced in cooperation with the National Constitution Center, each 90 minute program will air live on C-SPAN and C-SPAN3 on Monday nights at 9 p.m. ET, beginning October 5, 2015 and going through December 21, 2015.
