Question: What kind of pilgrims gathered at the protest against Saifuddin Kitchlew's arrest
Context: The Abortion Caravan was a feminist protest movement formed in Canada in 1970 by members of the Vancouver Women's Caucus.  It was created to oppose the 1969 amendments to the Criminal Code which restricted legal access to abortion.  Members formed a caravan, emulating previous peripatetic protest movements, traveled to Ottawa and gathered support along the way.  Hundred of women across Canada engaged in protests at the Prime Minister's official residence, burning effigies and leaving a black coffin at the front door.  These protests sparked wider debate and had an impact on abortion laws being struck down in 1988. The protest against conscription of yeshiva students was a mass rally held in Jerusalem on March 2, 2014.  Its organizers called for a "million-man protest" against a proposed law overturning the exemption from military service for Haredi talmudical students and criminalizing those who refused to enlist in the Israel Defense Forces.  From 300,000 to 600,000 people gathered in one of the largest protests in Israeli history. Women Strike for Peace (WSP, also known as Women for Peace) is a United States women's peace activist group.

It was the largest national women's peace protest of the 20th century.  About 1,500 women led by Dagmar Wilson gathered at the foot of the Washington Monument and President John F. Kennedy watched from a window at the White House.  The protest helped "push the United States and the Soviet Union into signing a nuclear test-ban treaty two years later". Saifuddin Kitchlew (15 January 1888 – 9 October 1963) was an Indian freedom fighter, barrister and an Indian Muslim nationalist leader.

He is most remembered for the protests in Punjab after the implementation of Rowlatt Act in March 1919, after which on 10 April, he and another leader Dr. Satya Pal, were secretly sent to Dharamsala.  A public protest rally against their arrest and that of Gandhi, on 13 April 1919 at Jallianwala Bagh, Amritsar, led to the infamous Jallianwala Bagh massacre. He was awarded the Stalin Peace Prize (now known as Lenin Peace Prize) in 1952.

The protest march was fueled by the indication of junta leader Captain Moussa Dadis Camara breaking his pledge to not run in the next presidential vote due in January 2010.
