No, Rosa Parks was not a part of the Selma March, also known as the Selma to Montgomery marches, which took place in March 1965.
While Rosa Parks is a pivotal figure in the Civil Rights Movement, most famously known for her act of defiance by refusing to give up her bus seat to a white passenger in Montgomery, Alabama, in 1955, her involvement in the movement took place before the Selma marches.
The Selma marches were organized to protest against systemic racial discrimination and to demand voting rights for African Americans, a cause Rosa Parks certainly supported. However, she was not physically present during the marches themselves, which were led by other civil rights leaders, including Martin Luther King Jr. and John Lewis.
Rosa Parks remained an influential figure and continued her activism after the events in Selma, but her role was more about inspiring and mobilizing others rather than participating in this particular march.
