(CNN) Today marks the 60th anniversary of Rosa Parks taking a stand.

The 42-year-old seamstress and secretary of her local NAACP chapter defied Jim Crow laws that called for the separation of the races by refusing to move to the back of a bus to allow a white man to have her seat.

That defiant act in Montgomery, Alabama, in 1955 was a pivotal point in the civil rights movement and transformed Parks into a symbol of the struggle. Social media marked the day and remembered her, with some taking note of the current plight of African-Americans.

Parks died in 2005 at the age of 92. In a 1995 interview , she said she wasn't angry about being asked to leave her seat, just resolute.

"I don't remember feeling that anger, but I did feel determined to take this as an opportunity to let it be known that I did not want to be treated in that manner and that people have endured it far too long," she said.
